What is "ampulla"?
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.
Examples
1. This ampulla contained a viscous fluid.
2. Each individual ampulla is connected to a tube foot.
3. Together, the foot and ampulla look kind of like an eyedropper.
4. Fertilization by a spermatozoon, when it occurs, usually takes place in the ampulla - the widest section of the fallopian tube.
