壶腹, 内耳半规管内的膨胀区域
the expanded region within the semicircular canals of the inner ear
The ampulla is a specialized structure located within the semicircular canals of the inner ear. It contains the crista ampullaris, which is a sensory organ responsible for detecting rotational movements of the head. The hair cells within the ampulla sense the movement of the fluid within the canals and send signals to the brain, contributing to our sense of balance and equilibrium.
