| ringed hair | A rare condition in which the hair shows alternate pigmented and bright segments, the latter due to air cavities within the cortex. Synonym: leukotrichia annularis, pili annulati, thrix annulata, trichonosus versicolor. (05 Mar 2000) |
| root hair cell | <botany> Root epidermal cell, part of which projects from the root surface as a thin tube, thus increasing the root surface area and promoting absorption of water and ions. (18 Nov 1997) |
| club hair | A hair in resting state, prior to shedding, in which the bulb has become a club-shaped mass. (05 Mar 2000) |
| cochlear hair cell | <anatomy> The sound sensing cell of the inner ear. The cells have modified ciliary structures (hairs), that enable them to produce an electrical (neural) response to mechanical motion caused by the effect of sound waves on the cochlea. Frequency is detected by the position of the cell in the cochlea and amplitude by the magnitude of the disturbance. (18 Nov 1997) |
| cochlear hair cells | Sensory cell's in the organ of Corti in synaptic contact with sensory as well as efferent fibres of the cochlear (auditory) nerve; from the apical end of each cell about 100 stereocilia extend from the surface and make contact with the tectorial membrane. Synonym: Corti's cells. (05 Mar 2000) |

Such hairs are totally unlike those of vertebrates in structure, composition, and mode of growth. 5. An outgrowth of the epidermis, consisting of one or of several cells, whether pointed, hooked, knobbed, or stellated. Internal hairs occur in the flower stalk of the yellow frog lily (Nuphar). 6.
