Ectropion is defined as the outward turning of which structure?

Explanation:
Ectropion refers to the outward turning of the eyelid margin, typically the lower lid, away from the eyeball. This position exposes the inner conjunctival surface and can lead to tearing, irritation, and exposure-related ocular surface problems. It’s distinct from entropion, which is the inward turning of the eyelid. The other options—wrist, knee, and eye—do not describe lid malposition; ectropion specifically involves the eyelid turning outward.
