Dilated end of each of the semicircular canals; contains ampullary crest - see below.
the swelling at the base of each semicircular canal; it contains sensory cells which detect movement of the fluid within the canals.
Sensory cell containing area at the base of the semicircular canals. (See Semicircular Canals).
the dilated portion of a canal or duct especially of the semicircular canals of the ear
A widening of the tube e.g. the end of the vas deferens in which some sperm is stored. Also the ovarian end of the fallopian tube where fertilisation takes place.

the widest part of the fallopian tube where fertilization of the egg occurs.
The enlargement at the base of each semicircular canal...contains sensory cells which detect movement of the fluid in the semicircular canals.
A localized dilation in the lumen of a canal or passageway.
The dilated or expanded end of each of the three membranous semicircular ducts of the inner ear.
