Question

What are the two functions of the sclera of the eye?

It focuses the light on the retina.
It protects the eye.
It serves as an attachment for the extrinsic muscles.
It supplies the eye with oxygen (it contains most of the eye's blood vessels)

Answer 1

The sclera of the eye has two functions: protecting the eye and serving as an attachment for the extrinsic muscles.

Step-by-step explanation:

The sclera is the tough, white outer layer of the eye. It has two main functions:

1. Protecting the Eye: The sclera provides structural support and helps to safeguard the delicate inner structures of the eye from injury.
2. Serving as an Attachment for Muscles: The extrinsic eye muscles, which are responsible for eye movement, are attached to the sclera. These muscles allow the eye to move in different directions.

Although the sclera contains blood vessels, its main role is not to supply the eye with oxygen. The cornea, the transparent front part of the eye, is responsible for oxygen absorption.
