Answer 1

vascular layer

Step-by-step explanation:

The wall of the eyeball is made up of three layers which are a fibrous tunic, vascular tunic, and retina, also known as an inner tunic. The middle layer of the eyeball is the vascular tunic or uvea which in turn is composed of three parts: choroid, ciliary body, and iris.

Choroid becomes the ciliary body in the anterior portion of the vascular tunic. The ciliary body is a dark brown structure and contains melanin-producing melanocytes. Other structural components of the ciliary body are ciliary processes and ciliary muscle. The ciliary processes arise as protrusions or folds on the internal surface of the ciliary body.
