Which structure provides stiffness and shape to the eyelid as its framework?

• A. Tarsus
• B. Orbit
• C. Conjunctiva
• D. Oculus

Answer: (A)

The eyelid’s stiffness and shape come from the tarsal plates, the dense connective tissue that form the eyelid’s framework. These tarsus plates create a rigid base for the lid margin, support the lashes, and serve as attachment points for the muscles that move the eyelid, helping it hold its contour. The orbit is the bony eye socket, not the eyelid’s framework; the conjunctiva is the mucous membrane lining the lid’s interior, and the oculus refers to the eyeball itself.
