Chapter 35, Problem 1PL

The cornea and the sclera compose the ______ layer

a. outer

b. middle

c. inner

d. gel

Expert Solution & Answer

Summary Introduction

Introduction :

The cornea is a transparent structure of the eyes that covers the pupil, iris, and anterior chamber of the eyes. It refracts light with the anterior chamber and the lens. While Sclera (white part of the eye) is the fibrous, opaque, and protective layer of the eye that mainly contains collagen and some elastic fiber

Answer to Problem 1PL

Correct answer :

The correct answer is option (a) outer.

Explanation of Solution

Explanation/justification for the correct answer :

Option (a) outer. The cornea and the sclera compose the outer layer (fibrous tunic) of the eyes. Both are the connective tissues that contain collagen fibrils embedded in the proteoglycan rich extrafibrillar matrix. This dense connective tissue layer of cornea and sclera protects the eyeball and maintains its shape. So, the correct answer is option (a).

Explanation for incorrect answer :

Option (b) middle. The middle layer (vascular tunic) of the eyes is composed of the iris, choroid, and the ciliary body, which is responsible for the nourishment. So, this is an incorrect option.

Option (c) inner. The inner layer (nervous tunic) of the eyes is the layer of photoreceptors and the neurons. It is consists of the retina. So, this is an incorrect option.

Option (d) gel. Gel (vitreous) is found filled in the interior of the eyes that help the eyes to maintain a particular round shape. So, this is also an incorrect option.
