Hair Cells in the Crista Ampullaris are _ _

Question

Hair cells in the crista ampullaris are _ _.
A) embedded in the otolithic membrane
B) responsive to gravitational pull
C) topped with "heavy" crystals called otoliths
D) embedded in a gelatinous cap

Accepted Answer

Hair cells in the crista ampullaris are embedded in a gelatinous structure called the cupula, not the otolithic membrane, and they respond to changes in rotational acceleration rather than gravitational pull. Otoliths are associated with the utricle and saccule, not the crista ampullaris.
