The orbicularis oculi muscle ( Latin for "eye ring muscle") is a skeletal muscle that encircles the eye in a ring shape and serves to close the eyelid gap and thus also the eyelid closure reflex . It belongs to the facial muscles .
The muscle is innervated by the facial nerve (VII. Cranial nerve ) , which sends nerve fibers to this muscle via the parotid plexus . The blood supply takes place via the ramus zygomaticoorbitalis of the arteria temporalis superficialis .
The pars lacrimalis of the orbicularis oculi muscle is called the Horner muscle , was first described in 1745 by Joseph-Guichard Du Verney and named after the anatomist William Edmonds Horner (1793-1853).
