1) one of the areas of specialized sensory epithelium in the ampullae of the semicircular canals of the ear serving as end organs for the labyrinthine sense called also crista ampullaris2) a membranous spiral fold running the length of the body of certain spirochetes3) an elevation of the surface of a bone for the attachment of a muscle or tendon4) any of the inwardly projecting folds of the inner membrane of a mitochondrion* * *
n. (pl. cristae)1. the sensory structure within the ampulla of a semicircular canals within the inner ear. The cristae respond to changes in the rate of movement of the head, being activated by pressure from the fluid in the semicircular canals.2. one of the infoldings of the inner membrane of a mitochondrion.3. any anatomical structure resembling a crest.* * *
