Understanding the Bony Labyrinth: Cochlea, Vestibule & Semicircular Canals

1. Cochlea: The cochlea is a spiral-shaped structure that houses the auditory receptors (hair cells) responsible for hearing.

2. Vestibule: The vestibule is located in the central part of the bony labyrinth and contains the saccule and utricle, which are responsible for our sense of balance (equilibrium).

3. Semicircular canals: There are three semicircular canals, oriented in different planes, that play a role in our sense of balance and spatial orientation by detecting angular acceleration.
