Question

practice it snail - shaped organ in the inner ear that contains sensory receptors for hearing cochlea lobule ganglia ganglion fovea

Explanation:

The cochlea is a snail - shaped structure in the inner ear. It contains hair cells which are the sensory receptors for hearing. When sound waves cause vibrations in the cochlea, these hair cells convert the mechanical energy into electrical signals that are sent to the brain.
A lobule is a small lobe, often referring to a part of an organ like the earlobe (lobule of the auricle), but it has no role in hearing sensory reception.
Ganglia (plural of ganglion) are clusters of nerve cell bodies. They are not the snail - shaped hearing sensory receptor - containing structure in the inner ear.
The fovea is a part of the eye (in the retina) responsible for sharp central vision, not related to the ear or hearing.

cochlea
