conjunctiva 

A thin transparent mucous membrane lining the posterior surface of the eyelids from the eyelid margin and reflected forward onto the anterior part of the eyeball where it merges with the corneal epithelium at the limbus. It thus forms a sac, the conjunctival sac, which is open at the palpebral fissure and closed when the eyes are shut. The depths of the unextended sac are 14-16 mm superiorly and 9-11 mm inferiorly. The conjunctiva is divided into three portions: (1) The portion that lines the posterior surface of the eyelids is called the palpebral conjunctiva. It is itself composed of the marginal conjunctiva, which extends from the eyelid margin to the tarsal conjunctiva; the tarsal conjunctiva, which extends from the marginal conjunctiva to the orbital conjunctiva; and the orbital conjunctiva, which extends from the tarsal conjunctiva to the fornix. (2) That lining the eyeball is the bulbar conjunctiva. It is itself composed of the limbal conjunctiva, which is fused with the episclera at the limbus and the scleral conjunctiva, which extends from the limbal conjunctiva to the fornix. (3) The intermediate part forming the bottom of the conjunctival sac, unattached to the eyelids or the eyeball and joining the bulbar and the palpebral portion is called the fornix (conjunctival fold, cul-de-sac). See dyskeratosis; lid eversion; conjunctival gland; Krause's end bulbs; subtarsal sulcus.
