hair cell

n.
A cell with hairlike processes, especially one of the sensory epithelial cells present in the organ of Corti.

hair cell

(hār sel)
Sensory epithelial cells present in the spiral organ (organ of Corti), in the maculae and cristae of the membranous labyrinth of the ear, and in taste buds; they are characterized by having long stereocilia or kinocilia (or both) that, seen with the light microscope, appear as fine hairs.

hair cell

An epithelial cell possessing stereocilia in the maculae, cristae ampullaris, and the organ of Corti. These cells are receptors for the senses of position and hearing.

hair cell

a sensory epithelial cell of vertebrates that acts as a mechanoreceptor, possessing either one nonmotile cilium (kinocilium) or many nonmotile cilium-like projections of the surface (stereocilia). Such cells are found in the LATERAL-LINE SYSTEM and the ear.
