Thereof, what is the fibrous tunic of the eye?

Fibrous tunic of eyeball. Horizontal section of the eyeball. (Cornea labeled at top, sclera labeled at center right.) The sclera and cornea form the fibrous tunic of the bulb of the eye; the sclera is opaque, and constitutes the posterior five-sixths of the tunic; the cornea is transparent, and forms the anterior sixth

Subsequently, question is, what are the three tunics of the eye and their functions? The structure of the mammalian eye has a laminar organization that can be divided into three main layers or tunics whose names reflect their basic functions: the fibrous tunic, the vascular tunic, and the nervous tunic.

Additionally, what is the function of the vascular tunic?

Vascular tunic: The vascular tunic, as the name implies, is a network of blood vessels that supply oxygen and nutrients to the tissues of the eye.

What are the 3 layers of the eyes?

The eye is made up of three layers: the outer layer called the fibrous tunic, which consists of the sclera and the cornea; the middle layer responsible for nourishment, called the vascular tunic, which consists of the iris, the choroid, and the ciliary body; and the inner layer of photoreceptors and neurons called the
