Study Notes

Vestibular System Function

The vestibular system is responsible for maintaining balance, posture, and spatial orientation.

Peripheral Vestibular System Location

The peripheral vestibular system is located in the inner ear, within the temporal bone.

Bony Labyrinth Components

The bony labyrinth consists of three semicircular canals and the otolith organs (utricle and saccule).

Hair Cell Function

Hair cells in the vestibular system convert mechanical energy from movements into electrical signals that are transmitted to the brain.

Vestibular System Monitoring

The vestibular system monitors the position and movement of the head, detecting changes in linear acceleration, angular velocity, and rotational movements.
