What is the clear mucous membrane that covers the white part of the eye called?

The clear mucous membrane that covers the white part of the eye is known as the conjunctiva. This membrane serves important functions, including protection and lubrication of the eye. It plays a critical role in maintaining eye health by producing mucus and tears, which help keep the surface of the eye moist. Additionally, the conjunctiva is crucial in serving as a barrier against potential pathogens that could cause infections.

The cornea, while also a significant part of the eye, is the transparent front layer that covers the iris and pupil and is primarily responsible for focusing light. The sclera is the tough, white outer layer of the eyeball, providing structure and protection, but it does not have the mucous quality of the conjunctiva. The retina, on the other hand, is the innermost layer at the back of the eye that detects light and sends visual signals to the brain, but it does not cover the white part of the eye. Hence, understanding the specific roles of these different structures highlights why the conjunctiva is the correct answer in this context.
