Solution
The functions of the sclera are:
-
Protects internal structures: The sclera is a tough, fibrous tissue that covers most of the eye. It serves as a protective layer for the delicate internal structures of the eye, including the retina, the choroid, and the optic nerve.
-
Provides a point of attachment for the extrinsic eye muscles: The extrinsic eye muscles, which control the movement of the eye, are attached to the sclera. This allows the eye to move in various directions.
-
Maintains the shape of the eye: The sclera helps to maintain the shape of the eye. It provides the eye with its characteristic round shape.
The sclera does not convert light into action potentials, this is the function of the retina. Also, it does not provide nutrients to the cornea, this is primarily the function of the tears and the aqueous humor.
