Name: auditory receptor cell
Synonyms: auditory hair cell, auditory receptor cells
Definition: A mechanoreceptor cell located in the inner ear that is sensitive to auditory stimuli. The accessory sensory structures are arranged so that appropriate stimuli cause movement of the hair-like projections (stereocilia and kinocilia) which relay the information centrally in the nervous system.
Ontology: Anatomy Ontology [ZFA:0009121]
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.
