What does eyelid mean eyelid

The eyelid means the soft skin musculature in front of the eyeball, with eyelashes growing on the edges, which protects the eyeball.

The pronunciation of the eyelid is yǎn jiǎn. The main structure of the eyelid is divided into upper eyelid, lower eyelid, medial canthus, lateral canthus, upper lacrimal point, lower lacrimal point, eyelid margin and palpebral fissure, etc. The eyelids are made up of **, connective tissue, muscles, glands, and conjunctiva.

When the upper and lower eyelids of normal people are closed, the upper and lower eyelid lines are tightly connected; When the eyes are opened, the upper eyelid is lifted upwards and the lower eyelid is slightly drooping; When the eyes are naturally opened and the eyes are horizontally forward, the upper eyelid covers the corneal line about 2 mm, and the entire pupil area is completely exposed, allowing light to pass through unobstructed, ensuring normal visual function.

The eyelashes at the eyelid margin are neatly arranged and protruding forward and outward, without contact with the cornea, which can prevent dust and sweat from invading the eye and play a role in protecting the eyeball. Any lesion that may cause eyelid tissue defects, abnormal position, and dysfunction of eyelid opening and closing can affect the normal physiological function of the eyelids, resulting in the loss of eye protection and the safety of the eyeball. Blepharopathy includes abnormal position of the eyelids, inflammation, tumors, etc.

Normally, the eyelids open and close every 2 8 seconds, which is called blinking. By opening and closing the eyelids, the eyeball can be moistened and the cornea shiny, and the conjunctival sac dust and bacteria can be removed. If there is no lid covering, the eyeball will be exposed, and the eyeball will be dry and uncomfortable if it is attacked by a foreign body.

The eyelid acts like a loyal guard, guarding the eyeball. When a foreign body strikes, the eyelid closes under the command of the central nervous system to prevent damage to the eyeball by the foreign body. In addition, when there is strong light hitting the eye, the eyelid also closes to prevent damage to the optic nerve in the fundus by bright light.

It means eyelids.

Pronunciation: yǎn jiǎn

Analysis: The eyelid is located in front of the eyeball, divided into upper and lower eyelids, and the cracks between the eyelids are called palpebral fissures. The eyelid is made up of **, connective tissue, muscles, glands, and conjunctiva, which are important structures to protect the eyeball.

Example: Researchers refer to the initiating part of this blinking system as the "eyelid suspension," which is a piece of muscle or structure that supports the eyelid.
