What parts of the ear anatomy belong to inner ear?

Parts of the Ear Anatomy that belong to the Inner Ear:

1. Cochlea: A spiral-shaped, bony structure in the inner ear that contains the sensory cells responsible for hearing.

2. Vestibular System: A part of the inner ear responsible for balance and spatial orientation. It consists of three semicircular canals and two otolith organs (the utricle and saccule).

3. Semicircular Canals: Three fluid-filled canals in the inner ear that detect angular acceleration (rotation) of the head.

4. Otolith Organs (Utricle and Saccule): Two sac-like structures in the inner ear that contain sensory cells that detect linear acceleration (movement in a straight line) and gravity.

5. Cochlear Nerve: A bundle of nerve fibers that carries auditory information from the inner ear to the brain.

6. Vestibular Nerve: A bundle of nerve fibers that carries balance and spatial orientation information from the inner ear to the brain.
