Provide awareness of spatial position and self-motion
Where is the peripheral vestibular system located?
Within the inner ear
What are the components of the bony labyrinth?
Three semicircular canals, cochlea, and vestibule
What do hair cells in the vestibular system do?
Convert displacement due to head motion into neural firing

Motion and position of the head in space by detecting angular and linear acceleration.
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.
Test your knowledge of the anatomy, physiology, and motor control of the vestibular system located within the inner ear. Learn about its components including the peripheral apparatus, central processors, and motor output.
