The palpebral part of the muscle is thin & pale; it arises from the bifurcation of the medial palpebral ligament, forms a series of concentric curves, & is attached to the lateral palpebral raphe at the outer side of the eye. The orbicularis oculi is a muscle that surrounds the eye in the orbit (eye socket). The orbicularis oculi is a flat muscle that it is one of three muscles in the circumorbital and palpebral muscle group, which are muscles that surround the eyes. To unlock this lesson you must be a Study.com Member. The orbicularis oculi is a periorbital muscle which means it surrounds each eye socket. The orbicularis oculi muscle receives its blood from the branches of the facial artery and superficial temporal artery (which are branches of the external carotid artery), as well as the ophthalmic artery (which is a branch of the internal carotid artery). Learn about its anatomy and function at Kenhub! The preseptal section is involved in both the voluntary forced closure as well as the involuntary blink closure of the eye and keeping the eyelids closed during sleep. The function of the orbicularis oculi depends on which part of the muscle contracts. The orbicularis oculi muscle is not only responsible for actively closing the eyes, but also for much of the facial expression made around the eyes. The orbicularis oculi muscle serves as the main protractor of the eyelid, and is divided into orbital (helps in voluntary forced lid closure) and palpebral component (helps in involuntary closure). Anatomically, the lower eyelid can be divided into the anterior (skin and orbicularis oculi muscle), middle (orbital septum and orbital fat), and posterior lamellae (tarsus and conjunctiva) sections (See Figure 2). The orbicularis oculi muscle is a muscle surrounding each of the eyes and lies directly underneath the skin. Enrolling in a course lets you earn progress by passing quizzes and exams. The orbicularis oculi originates from multiple locations, which include: The orbicularis oculi inserts onto multiple locations, which include: There are three parts to the orbicularis oculi, which include: Muscle action is very similar to muscle function. These sections have a complex arrangement of attachments to the surrounding structures. The orbicularis oculi is a muscle that surrounds the eye in the orbit or eye socket, and it plays an important role in closing the eyes and producing tears. The main source for overuse of this muscle is poor eyesight without the actual corrective lenses. That helps support ScienceABC with some money to maintain the site. Intracranially, the seventh cranial nerve arises in the pons of the brainstem. The other two muscles of this group are corrugator supercilia and levator palpebrae superioris. It passes through the internal acoustic meatus & then the facial canal of the temporal bone. When the entire orbicularis oculi muscle is brought into action, the skin of the forehead, temple, and cheek is drawn toward the medial angle of the orbit, and the eyelids are firmly closed, as occurs in photophobia. Thus, damage to the nerve can produce a varied set of symptoms, depending on the site of the lesion. It travels through the cavernous sinus and then splits off a major branch call the ophthalmic artery. From the orbital margin, the muscle extends inward and inserts on the lateral palpebral raphe, which is a ligament that is located on the outer part of the eye socket. Tensor Tympani Muscle: Why Does Closing The Eyes Tightly Produce A Rumbling Sound In The Ears? The nerves that innervate the orbicularis oculi include temporal and zygomatic branches of facial nerve, which is the seventh cranial nerve (CN VII). A number of auxiliary muscles help in cooperating with the eyelid muscles. There are at least 3 clearly defined sections of the orbicularis muscle. It arises from the nasal part of the frontal bone, from the frontal process of the maxilla in front of the lacrimal groove, and from the anterior surface and borders of a short fibrous band, the medial palpebral ligament . Buccal - Innervates the orbicularis oris, buccinator and zygomaticus. Orbicularis oculi are situated superficial to the palpebral branches of the infraorbital nerve, which also perforated the muscle. Hold this position for 5 seconds & repeat while looking first to the left, then to the right. in Dietetics & Nutrition from Florida International University. #fca_qc_quiz_63410.fca_qc_quiz a:not( .fca_qc_share_link ), The first extracranial branch to arise isthe posterior auricular nerve. This exercise is done by partially winking one eye at a time & holding the position for a couple of seconds. This article incorporates text in the public domain from page 380 ofthe 20th edition of Gray's Anatomy (1918). The skin thus drawn upon is thrown into folds, especially radiating from the lateral angle of the eyelids; these folds become permanent in senescence, and form the so-called "crow's feet". Nasal portion of frontal bone: The frontal bone is the. 192 lessons. Superficial fibers radiate through the eyelid and orbicularis oculi to finally attach to the skin of the superior eyelid . The orbicularis oculi muscle is responsible for eyelid closure. The lacrimal part of the orbicularis oculi draws the eyelids and the ends of the lacrimal canals medialward and compresses them against the surface of the globe of the eye, thus placing them in the most favorable situation for receiving the tears; it also compresses the lacrimal sac. Branches of the facial artery and superficial temporal artery supply the orbicularis oculi muscle. This information is intended for medical education, and does not create any doctor-patient relationship, and should not be used as a substitute for professional diagnosis and treatment. Blood supply of a muscle refers to what arteries bring blood to the muscle. These muscles have two origins, one on the sternum and the other on the clavicle. The orbital portion arises from the medial canthal tendon and laterally inserts into the zygoma. Raise your eyebrows & eyelids as far as you can as if you were trying to touch the top of your head with your eyelids & eyebrows. All these muscles are derivatives of the second pharyngeal arch. Whenever the orbicularis oculi muscle contracts, the tears are drawn from the tear film via the lacrimal pump system.[1][2][3]. These points of origin include the nasal portion of the frontal bone, frontal process of the maxilla, medial palpebral ligament, and lacrimal bone. The muscle helps the eye toclose or blink. I, personally, have always associated the idea of resting with certain relevant muscles/muscle groupsbecoming relaxed, which ultimately leads to the relaxation of the concerned body part. Within the facial canal, three important events occur: The facial nerve then exits the facial canal (and the cranium) via the stylomastoid foramen. Additionally, the muscle action of the orbicularis includes compressing or squeezing the lacrimal sac. The orbicularis oculi is a muscle in the face that closes the eyelids. When a muscle is innervated, it receives electrical signals from the brain through a network of nerves. Br J Anaesth 2000; 85:856. The frontalis muscle has no bony attachments. It is derived from the mesenchyme of the second pharyngeal arch. There are several arteries that supply blood to the orbicularis oculi, including the superficial temporal, maxillary, and facial arteries.

Orbicularis oculi Location The facial muscle is located in the orbit of each eye. The levator palpebrae superioris lifts the upper eyelid and exposes the front of the bulb of the eye. So, the first thing I did after getting my first pair of spectacles was to try and figure out ways to get my vision back to normal, i.e., 20/20. Facial plastic surgery : FPS. Muscles of the Body for Health Professionals, Corrugator Supercilii Muscle: Definition & Innervation, Psychological Research & Experimental Design, All Teacher Certification Test Prep Courses, Occipitalis Muscle: Definition, Function & Action, What is the Frontalis Muscle? The orbicularis oculi muscle has three distinct parts - palpebral, lacrimal and orbital. Orbital part tightly closes the eyelids. [7][8], Choi Y,Kang HG,Nam YS,Kang JG,Kim IB, Facial Nerve Supply to the Orbicularis Oculi around the Lower Eyelid: Anatomy and Its Clinical Implications. The main trunk of the nerve, now termed the motor root of the facial nerve, continues anteriorly and inferiorly into theparotid gland(note the facial nerve does not contribute towards the innervation of the parotid gland, which is innervated by the glossopharyngeal nerve). The arteries that supply blood to the orbicularis oculi include the maxillary, superficial temporal, facial and ophthalmic arteries. All other trademarks and copyrights are the property of their respective owners. [insert object name]) in real life to get things done. It is used in looking up, and increasing vision if there is insufficient light or when objects are far away.[3]. In addition, the orbital & palpebral portions can act independently of each other, as in the furrowing of the brows by contraction of the orbital to decrease glare while maintaining the eyes open by virtue of the relaxation of the palpebral. It then passes through the parotid gland where it splits into five branches, which innervate the muscles of facial expression. The muscles of facial expression will be paralysed or severely weakened. It provides motor innervation to the some of the muscles around the ear.

In the superior border of the thyroid cartilage in the neck, each common carotid artery split into the internal & external carotid arteries. #fca_qc_quiz_63410.fca_qc_quiz button.fca_qc_next_question { background-color: #dbdbdb; Is Mathematics An Invention Or A Discovery? The ophthalmic artery enters the orbit through the optic canal. When the orbicularis oculi contracts, it squeezes these lacrimal sacs which causes the tears flow to the nasolacrimal duct and then drain into the nose where they are reabsorbed. The lacrimal orbicularis ease the tear pump into the lacrimal sac. In contrast, the lower half of the muscle nerve supply is a zygomatic branch of the seventh cranial nerve (facial nerve). The antagonist muscles to the frontalis muscle are the orbicularis oculi, corrugated, and procerus muscles. The orbicularis oculi muscle is divided into three main parts: To unlock this lesson you must be a Study.com Member.

Attachments - Originates from the medial orbital margin, the medial palpebral ligament, and the lacrimal bone. eye socket) and it. Create your account. When this muscle receives this impulse, it will contract and close the eyelids and/or squeeze the lacrimal sac. The orbicularis functions to voluntarily and involuntarily close the eye lids. 2019 Feb; [PubMed PMID: 30308706], Mustak H,Rafaelof M,Goldberg RA,Rootman D, Use of Botulinum Toxin for the Correction of Mild Ptosis. Where is the orbicularis oculi located? Dan has taught college Nutrition, Anatomy, and Medical Terminology courses. The pretarsal portion of the muscle is anterior to the lower and upper tarsal plates. border: #151515 2px solid; They insert on the mastoid process of . Within the orbit, it split into various branches, including the lacrimal artery, supraorbital artery, ethmoidal arteries, supratrochlear artery, central retinal artery, ciliary arteries, & muscular branches. Hemmerling TM, Schmidt J, Hanusa C, et al. This occurs when the muscle contracts. The muscle action of the orbicularis oculi is to pull the eyelids over the eyes. box-shadow: 0 2px 0 0 #3c7d73; Like most facial muscles, the orbicularis oculi muscle too has a complex anatomy. The facial artery then courses from the mandibular area, up the side of the nose and to the medial canthus of the eye, where it is called the angular artery. Subsequent lack of irrigation increases the risk of corneal inflammation & ulcers. The clinical presentation of BEB consists of bilateral involuntary spasms of one or more of the eyelid protractor muscles including the orbicularis oculi, procerus and corrugator muscles, with symptoms ranging from mildly increased blink rate to forceful eyelid closure that can result in functional blindness. The nerve that attaches to and innervates the orbicularis oculi muscle is the seventh cranial nerve (CN VII), which is commonly known as the facial nerve. border: #dbdbdb 0px solid; However, it is not clear whether the lacrimal section is a separate section, or whether it is just an extension of the preseptal and pretarsal sections.[1][2]. - Definition, Scale & Tests, Extramedullary, Trilineage & Fetal Hematopoiesis, What is Carpal Tunnel Syndrome? The palpebral part of the muscle aids in an involuntary closure of the eyelids, typically during sleep, unlike the orbital fiber. Attachments - Originates from the medial orbital margin, the medial palpebral ligament, and the lacrimal bone. Palpebral part: The palpebral part is the portion of the orbicularis oculi that form the eyelids, and it controls the involuntary, gentle closure of the eyelids. The orbicularis oculi is not only responsible for actively closing the eyes, but also for much of the facial expression made around the eyes. Laterally, the preseptal orbicularis oculi muscle attaches to Whitnalls lateral orbital tubercle, which is deep to the lateral palpebral raphe. This means that whenever you This muscle inserts onto the lateral palpebral raphe & superior and inferior tarsal plates, which are also known as the eyelids. While in action, the skin undergoes folding and radiates from the lateral angle of the eyelids. The deep or posterior head of the pretarsal orbicularis oculi muscle is also known as Horners muscle. The orbital section of the orbicularis oculi is more involved in the voluntary closure of the eyelid, such as with winking and forced squeezing. The palpebral portion of the muscle is thin and pale; it arises from the bifurcation of the medial palpebral ligament, forms a series of concentric curves, and is inserted into the lateral palpebral raphe at the outer canthus (corner) of the eye. For example, the biceps brachii is the muscle at the front of the upper arm, and when this muscle contracts, it pulls the forearm upwards to bend the elbow (also known as elbow flexion). Understand its functions and discover its location, along with the orbicularis oculis origin and insertion. Take your own here and learn something new and perhaps surprising. Hes a Harry Potter fan and tries, in vain, to use spells and charms (Accio! For example, when a person cries, tears will flow to the surface of the eyes, and some of these tears will drain into tiny openings known as puncta on the inner corers of the two eyelids. This muscle is located in each orbit (i.e. Horizontal resection of a strip of the hypertrophic muscle is carried out, which allows the flattening of the muscular bulge in an anteroposterior site. } This muscle has three main functions: To unlock this lesson you must be a Study.com Member. Necessary cookies are absolutely essential for the website to function properly. If not treated adequately, the poor closure of the eyelids can result in significant pain, corneal scarring, corneal ulcer, and ultimately corneal perforation with a possibleloss of the eye. From this origin, the fibers are directed laterally, forming a broad and thin layer, which occupies the eyelids or palpebr, surrounds the circumference of the orbit, and spreads over the temple, and downward on the cheek. Loss of function for any reason results in an inability to close the eye, necessitating eye drops at the minimum to surgical closure of the eye in extreme cases. Hold this position for five seconds & release the contraction. The orbicularis oculi originates from the frontal bone, maxilla, medial palpebral ligament, and lacrimal bone, and it inserts onto the lateral palpebral raphe and the upper and lower tarsal plates (eyelids). He has a B.S. These cookies do not store any personal information.

Do you like to sleep? Submandibular and sublingual salivary glands. This muscle is positioned directly under the skin, and it is located between three bones of the face that include the frontal bone, maxilla, and lacrimal bone. As mentioned earlier, the orbicularis oculi muscle helps to close your eyelid, while the levator palpebrae superioris muscle assists in opening it. The parasympathetic fibres of the facial nerve are carried by the greater petrosal and chorda tympani branches. The orbicularis oculi muscle is divided into2 sections, the orbital & palpebral sections. Associated pathology, similar to a lesion of the facial nerve seen in Bells palsy results in the inability to blink or close the ipsilateral eyelid. Fig 5 Right sided weakness of the muscles of facial expression, due to facial nerve paralysis. This muscle nerve supply is from the seventh cranial nerve . The medial fibers project the puncta lacrimale into the Lacus lacrimale to drain the tears from the eyes surface and move them through the lacrimal sac and duct. It is a circular band of muscle that surrounds the eye. } This part is responsible for the voluntary closure of the eyes and allows a person to close their eyes firmly. #fca_qc_quiz_63410.fca_qc_quiz div.fca_qc_question_response_item.correct-answer { Abstract Objective: To study the anatomical location of retro-orbicularis oculi fat (ROOF) in the upper eyelid and to investigate how ROOF affects the appearance of the upper eyelid. It originates from the nasal part of the frontal bone, from the frontal process of the maxilla in front of the lacrimal groove,-& from the anterior surface and borders of a short fibrous band, and the medial palpebral ligament. By visiting this site you agree to the foregoing terms and conditions. He is a Registered Dietitian (RD) and a Certified Exercise Physiologist (EP-C). The orbicularis oculi muscle lies directly underneath the surface the skin, around the eyes. It arises from the posterior crest and adjacent part of the orbital surface of the lacrimal bone, and passing behind the lacrimal sac, divides into two slips, upper and lower, which are inserted into the superior and inferior tarsi medial to the puncta lacrimalia; occasionally it is very indistinct. } Picture 2 Orbicularis oculi Picture 3 Orbicularis oculi, http://en.wikipedia.org/wiki/Orbicularis_oculi_muscle, http://www.lumen.luc.edu/lumen/meded/grossanatomy/dissector/mml/ooc.htm, http://www.innerbody.com/image_musfov/musc39-new.html, http://www.gpnotebook.co.uk/simplepage.cfm?ID=-1328545712, Last updated on March 21st, 2018 at 12:15 pm. The palpebral section is further subdivided into the preseptal and pretarsal sections. The orbicularis oculi originates (begins) from the front surface of the orbital margin, which is the rim of the eye socket. The orbicularis oculi is a muscle that surrounds each eye. It is a sphincter muscle arranged in concentric bands around the upper and lower eyelids. Levator palpebrae superioris: A small, thin muscle located in each orbit above each eye that elevates and retracts each eyelid. The preseptal portion is thin and pale, and is formed by two half-ellipses of muscle fibers bifurcated by the medial and lateral canthal tendons. Learn about the eyes orbicularis oculi muscle. It is generallya sphincter muscle that lies in the tissue of the eyelid and performs a host of ocular functions. Medial palpebral ligament: The medial palpebral ligament is a short ligament that connects the inner part of the eyelid to the medial/inner part of the orbit. These cookies do not store any personal information. The orbicularis oculi muscles are exceptionally close to the skin surface, with essentially no subcutaneous fat between its fibers and the dermis. The zygomatic branch courses medially & innervates the lower half of the orbicularis oculi muscle. You cannot control this muscle actively; it fires all on its own. The nerve passes through thepyramidal eminence to supply the stapedius muscle in the middle ear. Why Are There 24 Hours In A Day And 60 Minutes In An Hour? 5,000? Tensor Tympani Muscle: Why Do You Hear A Rumbling Sound When You Close Your Eyes Too Hard? It plays a key role in closing the eyelids and thus protecting the cornea from damage. Hypertrophy of the orbicularis oculi may produce bags under the lower eyelids known as festoons, although this is not the most common cause of baggy eyelids. The facial nerve is associated with the derivatives of the second pharyngeal arch: Fig 1 Overview of the anatomical course of the facial nerve. The nerve that is attached to a muscle is classified as that muscle's innervating nerve. Dan has taught college Nutrition, Anatomy, and Medical Terminology courses. . In the field of anatomy, the term oculi refers to eye. This muscle functions to close the eyes (both voluntarily and involuntarily), and it also functions to direct tears out of the eyes. These branches are the temporal branch, and zygomatic branch, and buccal branch, marginal mandibular branch, & cervical branch. do this exercise daily. The orbicularis oculi muscle is divided into three parts, with each part having slightly different functions. Since it pulls the eyebrows upward, it is the antagonist of the orbicularis oculi. This causes inefficient lubrication & a condition known as dry eye syndrome (keratoconjunctivitis sicca), which manifests with redness, inflammation, irritation, discharge, & fatigue of the eyes. - Types, Symptoms & Treatment, Sepsis Infection: Definition, Symptoms & Criteria, Working Scholars Bringing Tuition-Free College to the Community. This muscle also functions to direct tears out of the eyes. Innervation of a muscle refers to the nerve that delivers an electrical impulse from the brain to the muscle, and when the muscle receives this electrical impulse, it will contract. From here, its travelsacross (but not through) the foramen lacerum, combining with the deep petrosal nerve to form the nerve of the pterygoid canal. } This particular condition becomes permanent when an individual grows older, resulting in the formation of wrinkles. The orbicularis oculi is secured to the medial and lateral palpebral ligament forming a ring in the eyelid tissue centered about the anterior eye. The procerus (pyramidal) muscles, in the bridge of the nose, originate from the lower nasal bone to the lower forehead, on each side of the midline. [3] The palpebral portion contains the preseptal and pretarsal muscles. The point of insertion is also the part of the body that is moved by the muscle. The muscle can be divided into three types: orbital, preseptal and pretarsal (Source). It also assists in the drainage of tears from the eyes. Orbicularis oris is a circular muscle of the facial expression that controls the movements of the lips. In 28 hemifaces, the eyelids were dissected from the superficial to deep layers, and the appearance, location . This occurs when the muscle contracts. Tears can help remove foreign objects from the eyes and help keep the eyes properly moistened. The brain will send an electrical impulse through the facial nerve, and this impulse will then travel through the temporal and zygomatic branches until it reaches the orbicularis oculi. It forms connections between the superficial muscular aponeurotic system (SMAS) of the face and frontalis muscle, the temple and the cheek. The two roots travel through the internal acoustic meatus, a 1cm long opening in the petrous part of thetemporal bone. The orbicularis oculi is an orbital muscle of facial expression. The skin thus drawn upon is pitched into folds, especially radiating from the lateral angle of the eyelids; these folds become permanent in senescence, & form the so-known as crows feet. The orbital section of the orbicularis oculi muscle attaches medially to the anterior limb of the medial canthal tendon and the surrounding periosteum. Later it drags the eyebrows upward, it is the antagonist of the orbicularis oculi muscle. The orbicularis oculi muscle surrounds the eye socket and extends into the eyelid. The following sections describe where the orbicularis oculi originates and inserts. From this origin, the fibers are direct laterally, forming a broad & thin layer, which occupies the eyelids or palpebrae, surrounds the circumference of the orbit, & spreads over the temple,& downward on the cheek. [citation needed], A number of auxiliary muscles assist in cooperating with the eyelid muscles. Revisions: 6. Still within the temporal bone, the roots leave the internal acoustic meatus, and enter into the facial canal. 2019 Jan; [PubMed PMID: 30444788], Ferrazzano G,Conte A,Gigante A,Defazio G,Berardelli A,Fabbrini G, Disease progression in blepharospasm: a 5-year longitudinal study.
