Ampullary cupula - Wikipedia
The ampullary cupula, or cupula, is a structure in the vestibular system, providing the sense of spatial orientation. The cupula is located within the ampullae of each of the three semicircular canals.
Cupula - (Anatomy and Physiology I) - Fiveable
The cupula is a gelatinous, dome-shaped structure located in the ampulla of the semicircular canals within the inner ear, playing a crucial role in detecting rotational movements of the head.

2021年4月15日 · Introduction. The semicircular canals (SCCs) in the vestibular system detect the angular motion of the head 1. Three SCCs are approximately mutually orthogonal, each of which terminal dilated cavity contains a gelatinous structure called cupula (see Fig. 1).
The Semicircular Canals - Neuroscience - NCBI Bookshelf
When the head turns in the plane of one of the semicircular canals, the inertia of the endolymph produces a force across the cupula, distending it away from the direction of head movement and causing a displacement of the hair bundles within the crista (Figure 14.8A,B).
Ampullary cupula - e-Anatomy - IMAIOS
The ampullary cupula is a gelatinous body overhanging the hair cells of the ampullary crests of the semicircular ducts; sensory hair cells are immersed in it and movement of endolymphatic fluid causes the cupula to move across the hair cells of the ampullary crest.

2014年11月4日 · Three of them function as membranes (cupulae) in a liquid-filled cavity (Fig. 1A). The sensors are located in a widened part (ampulla) of a fluid filled ring system, the semicircular canals. The cupulae are fixed at the roof of the ampulla and ride on a barrel-like structure, the crista ampullaris.
