Orbicularis oculi muscle

The orbicularis oculi muscle (Latin for " eye ring muscle ") is an eye ring encompassing skeletal muscle, which is the conclusion of the palpebral fissure, and thus also the blink reflex.

It rises on the nose-side part of the frontal bone and maxilla, and the nose-lateral canthal tendon, surrounds the eye and the eyelids and is applied to the palpebral raphe lateralis.

The muscle is innervated by the facial nerve ( VII cranial nerve), which sends over the parotid plexus nerve fibers of this muscle. The blood supply is via the superficial temporal artery Ramus zygomaticoorbitalis.
