| Synonyms: | lateral crista ampullaris, lateral cristae, lateral semicircular canal sensory patch, lateral semicircular canal sensory patches, lc, medial crista |
| Definition: | Patch of thickened, pseudostratified epithelium that is associated with the lateral semicircular canal. It consists of regular arrays of sensory hair cells interspersed with supporting cells. The lateral crista has its own characteristic shape and polarity pattern.

| Name: | stereocilium |
|---|---|
| Synonyms: | |
| Definition: | An actin-based protrusion from the apical surface of auditory and vestibular hair cells and of neuromast cells. These protrusions are supported by a bundle of cross-linked actin filaments (an actin cable), oriented such that the plus (barbed) ends are at the tip of the protrusion, capped by a tip complex which bridges to the plasma. Bundles of stereocilia act as mechanosensory organelles. |
