An ampulla is a part of the inner ear that surrounds sensory receptors that are responsible for movement related sensory experiences like spatial awareness and pressure change. Ampullae (the plural of ampulla) are located throughout the semicircular canals of the inner ear. An ampulla contains both the crista and the cupula. The cupula moves as the fluid in the semicircular canal moves which provides us with a sense of spatial awareness and orientation. The crista is responsible for the sensory experience of vibrations and pressure changes.
