ampulla
ampulla
1. An enlargement at one end of each of the semicircular canals of the inner ear. Each ampulla contains a group of receptors – sensory hair cells – embedded in a gelatinous cap (cupula), which detects movement in one particular dimension, corresponding to the plane of the canal. Movement of the head causes the cupula (and the hairs within it) to bend in a direction opposite to that of the head movement (see illustration); this stimulates nerve impulses in the receptors, which are interpreted by the brain as movement in a particular dimension. 2. Any small vesicle or saclike process. 3. ampulla of Lorenzini See electroreceptor. |

ampulla
ampulla. A globular vessel for holding liquid. The term is used of:(1) bottle-shaped vessels, usually of glass, found at tombs in the catacombs, and previously thought to contain the blood of martyrs; (2) vessels of baked clay used to preserve oil from lights burnt in martyria; (3) vessels used for the sacramental oils. The most famous is that supposed to have been brought by a dove at the prayers of St Remigius for the Baptism of Clovis. The ‘Sainte Ampoule’ preserved at Reims is known to have been used for the coronation of French kings from 1131 to the Revolution.
