Definition
A clear mucous membrane that lines the inner surface of the eyelid and the exposed surface of the eyeball or sclera.
Etymology
From 1540s late Middle English, borrowing from Medieval Latin conjūnctīva (“serving to connect, connective”, feminine), ellipsis of membrāna conjūnctīva (“conjunctive membrane”).
Example Sentences
- "There is a third inner eyelid, highly developed and of beautiful mechanism: this is the nictitating membrane, or "winker" (nictito, I wink), a delicate, elastic, translucent, pearly-white fold of the conjunctiva. While the other lids move vertically and have a horizontal commissure, the winker sweeps horizontally or obliquely across the ball, from the side next the beak to the opposite."
