The bony labyrinth
What do hair cells located in each ampulla and otolith organ do?

Study Notes
- The vestibular system is located within the inner ear.
- Laterally, the vestibular system is bordered by the middle ear and medially, lies adjacent to the temporal bone.
- The vestibular system consists of three parts: peripheral apparatus, central processors, and motor output.
- The peripheral vestibular system helps to accomplish tasks by detecting motion and position of the head in space.
- The membranous labyrinth is suspended within the bony labyrinth by perilymphatic fluid and supportive connective tissue.
- Hair cells are located in each ampulla and otolith organ and are biological sensors that convert displacement due to head motion into neural firing.
