Conjunctiva

Conjunctiva, the mucous membrane of the eye and eyelids. It is described as being made up of three parts, named palpebral, scleral, and corneal. The palpebral conjunctiva lines the inner surface of the eyelids. The scleral conjunctiva is the portion which covers the sclerotic, the resistant supporting tissue of the eyeball, or "white of the eye" as it is termed. The corneal conjunctiva covers the anterior surface of the cornea, the transparent portion of the outer coat of the eyeball. These three portions are directly continuous with one another.
