Definitions:

Inner Ear

A complex structure in the ear responsible for hearing and balance, comprising the cochlea, vestibule, and semicircular canals.

Depolarization

Decrease in electrical charge across a membrane, usually due to the inward flow of sodium ions.

Hyperpolarization

Increase in electrical charge across a membrane, usually due to the inward flow of chloride or sodium ions or the outward flow of potassium ions.

Calcium Channels

Calcium channels are protein-based channels present in the cell membrane that facilitate the entry of calcium ions into cells, playing crucial roles in various physiological processes.
