Question
Chapter 15.4, Problem 4QC
Summary Introduction
To review:
The layer of the eyeball that is composed of photoreceptors
Introduction:
The eyeball is like a hollow sphere, which occupies the one-third portion of the anterior orbit. Rest of the portion is filled with the adipose tissue that provides a cushioning effect to the eyeball and holds it in position. The eyeball is consist of three tissue layers: fibrous, vascular, and neural layers.
