Orbicularis oculi

The orbicularis oculi is the ring of muscle around the eye, set around the upper and lower eyelids. Its main work is closing the lids, and it also helps tears drain. (StatPearls, Orbicularis Oculi Muscle; OpenStax A&P 2e, 11.3)

Where is the orbicularis oculi?

It lies just beneath the skin of the eyelids and stretches from the inner corner of the eye to the outer corner. (StatPearls, Orbicularis Oculi Muscle)

Almost no fat separates it from the skin. Its lower part contributes to the top of the cheek. (StatPearls, Facial Muscles and Cheeks)

What are the parts of the orbicularis oculi?

It has an orbital part and a palpebral part, each subdivided by function. (StatPearls, Orbicularis Oculi Muscle)

The orbital part attaches at the inner corner to the medial canthal tendon and the periosteum around it, and at the outer corner to the lateral palpebral raphe. At its edge it interweaves with neighboring muscles, among them the frontalis. (StatPearls, Orbicularis Oculi Muscle)

The palpebral part has preseptal, pretarsal and ciliary sections. The ciliary section, along the lid margin, shows as a colored line called the gray line. (StatPearls, Orbicularis Oculi Muscle)

About 88% of its fibers are fast-twitch, type II fibers. StatPearls names it and the zygomaticus major as the fastest-moving muscles in the body. (StatPearls, Orbicularis Oculi Muscle and Facial Muscles)

What does the orbicularis oculi do?

The orbital part closes the lids tight on purpose. The palpebral part does the blinking, both voluntary and involuntary. (StatPearls, Orbicularis Oculi Muscle)

Each blink squeezes the canaliculi, the small channels that carry tears to the lacrimal sac, and pulls the sac outward and forward. The negative pressure this creates draws tears into the sac and on down the nasolacrimal duct. (StatPearls, Orbicularis Oculi Muscle)

It also lowers the brows and makes the crow’s feet wrinkles at the outer corners of the eyes. (StatPearls, Facial Muscles)

Which nerve supplies the orbicularis oculi, and how does it form?

The facial nerve (cranial nerve VII) supplies it. Its temporal branch reaches the upper half, along with the frontalis and corrugator supercilii, and its zygomatic branch reaches the lower half. (StatPearls, Orbicularis Oculi Muscle and Facial Muscles)

When the muscle fails, as in Bell palsy, the eyelids no longer close as they should. (StatPearls, Orbicularis Oculi Muscle)

It develops from the mesenchyme of the second pharyngeal arch, the same arch as the orbicularis oris. (StatPearls, Orbicularis Oculi Muscle and Orbicularis Oris Muscle)
