Detailed explanation-1: -The eye itself can be divided into 3 concentric tunics plus the internal components. The three tunics from the outside surface of the eye inward are, (1) the fibrous tunic (cornea and sclera), (2) the vascular tunic (iris, ciliary body, and choroid) and (3) the neuroectodermal (nervous) tunic (retina).
Detailed explanation-2: -The outer layer or tunic (sclera, or white, and cornea) is fibrous and protective. The middle layer (choroid, ciliary body and the iris) is vascular.
Detailed explanation-3: -outer layer – made up of the sclera and cornea (called the fibrous tunic) middle layer – made up of the uvea (called the vascular tunic) inner layer – made up of the retina (called the neural tunic)
