The crista ampullaris
is the sensory organ of balance located in the semicircular canal
of the inner ear
. The function of the crista ampullaris is to sense angular acceleration and deceleration.
The inner ear is comprised of 2 specialized regions of the membranous labyrinth
: the saccule
and the utricle
The receptor cells located in the semicircular canal are innervated by the eighth cranial nerve, aka vestibulocochlear nerve (more specifically the vestibular portion).
