What is orbicularis oculi?

Oculi orbicularis muscles surround the eyes just below the skin of the upper and lower eyelids. These muscles that work as sphincters work to close the lids. Based on the effect zone, the orbicularis oculi muscles consist of the palpebral part, which is located in the lid itself, the orbital part that stretches from the upper eye fold to the forehead and the tear part that occupies the inner corner of the eye near the collection collection. The palpebral part of the muscle mediates the involuntary closure of the eyes such as flicker, while the orbital part of the orbicular vinegar provides voluntary eye closure, such as reaction to bright light. Because the orbicularis oculi is the only muscle capable of closing the lid, the impairment of this muscle causes the exposure to the eyeball, requiring lubricants and possibly surgery.

When the lids are closed, the tear part of the orbicularis oculi pulls the inner corners lid towards the nose and slightly turns them in. This action places small holes called Puncta, in the best position for collectingtears. The muscle also compresses the hell of the hell located near the nose. When the eye opens, the tears are expanding due to a vacuum created by compression and attracting tears from eye to bag. In this way orbicularis Oculi muscles act as part of a tear or tear pump.

is deep to orbicularis oculi, levator palpebrae superioris connects to the cartilage plate of the upper eyelid, lifts the lid and opens the eye. Its effect directly against the effect of orbicularis muscle. When levator muscle is active, lid lifting, orbital part of orbicularis can still download, grind the eyebrows, while the palpebral part of the muscle relaxes. The side zone of the orbicularis of the taddy face and the temple towards the eye, leading to the formation of the crows over time.

Oculi orbicularis muscle obtains its nerve supply from the nerve of the face on each side. Blefarospasm is a condition in which the eyelids are involuntarily twitching or flashing. In the case of BlefaRospasmus with orbicularis oculi muscles excessively download. In such cases, ophthalmologists are looking for sources of irritation on the eye surface such as dryness that can be managed by artificial tears. Alternatively, doctors treat benign basic bleparospasm due to the abnormal function of basal ganglia located in the brain stem with botulinum toxin injections.

Damage to the nerve of the face or temporary nerve dysfunction, called Bell's Palsy, leads to the inability to close the eye. Bell's palsy occurs in about two of each 10,000 people. Inflammation in the peripheral nerve of the face was associated with herpes, diabetes, sarcoidosis and Lyme disease. About 70 percent of Bell's Palsy cases is dealt with within a few weeks to months.
