the ______ is the snail-shaped structure of the inner ear.

cochlea
incus
tarsus
stapes

Explanation:

Analyze the first question on eye anatomy

Using the Ophthalmic Terminology knowledge point

The question asks for the structure that maintains the shape of the eye and protects its delicate inner layers.

• The sclera is the tough, fibrous white outer coat of the eye that maintains its shape and protects the inner structures.
• The choroid is the vascular middle layer.
• The conjunctiva is a thin mucous membrane covering the front of the eye and lining the eyelids.
• The cornea is the transparent front part of the eye that covers the iris and pupil.

Therefore, the correct option is sclera.

Analyze the second question on ear anatomy

Using the Otologic Terminology knowledge point

The question asks for the snail-shaped structure of the inner ear.

• The cochlea is the spiral, snail-shell-shaped cavity of the inner ear containing the organ of Corti, which produces nerve impulses in response to sound vibrations.
• The incus and stapes are middle ear ossicles (bones).
• The tarsus refers to a plate of connective tissue in the eyelid or the ankle bones.

Therefore, the correct option is cochlea.
