crista ampullaris









































the crista ampullaris is the sensory organ of rotation. they are found in the ampullae of each of the semicircular canals of the inner ear, meaning that there are 3 pairs in total. the function of the crista ampullaris is to sense angular acceleration and deceleration.

the inner ear comprises three specialized regions of the membranous labyrinth: the vestibular sacs – the utricle and saccule, and the semicircular canals, which are the vestibular organs, as well as the cochlear duct, which is involved in the special sense of hearing.

the vestibular system, which is responsible for the sense of balance in humans, consists of the otolith organs and the semicircular canals. illusions in aviation are caused when the brain cannot reconcile inputs from the vestibular system and visual system. the three semicircular canals, which recognize accelerations in pitch, yaw, and roll, are stimulated by angular accelerations; while the otolith organs, the saccule and utricle, are stimulated by linear accelerations. stimulation of the semicircular canals occurs when movement of the endolymph inside the canals causes movement of the crista ampullaris and the hair cells within them. stimulation of the otolith organs occurs when gravitational forces or linear accelerations cause movement of the otolith membrane, the otoliths, or the hair cells of the macula.
