| connective tissue cells | The cellular elements of the fibrous and nonfibrous components of the various forms of connective tissue. (12 Dec 1998) |
|---|---|
| pluripotent cells | Primordial cell's that may still differentiate into various specialised types of tissue elements; e.g., mesenchymal cell's. (05 Mar 2000) |
| contrasuppressor cells | A subpopulation of T-cells, distinct from T helper cells, which inhibit T suppressor cell function. (05 Mar 2000) |
| Corti's 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) |
| myoid cells | Flattened smooth muscle-like cell's of mesodermal origin that lie just outside the basal lamina of the seminiferous tubule. Synonym: peritubular contractile cells. (05 Mar 2000) |
| posterior cells | The posterior group of air cells of the ethmoidal sinus's; each sinus communicates with the superior meatus of the nasal cavity. Synonym: sinus ethmoidales posteriores, cellulae posteriores, posterior cells. (05 Mar 2000) |
| posterior ethmoidal air cells | The posterior group of air cells of the ethmoidal sinus's; each sinus communicates with the superior meatus of the nasal cavity. Synonym: sinus ethmoidales posteriores, cellulae posteriores, posterior cells. (05 Mar 2000) |
| haematopoietic stem cells | Progenitor cells from which all blood cells derive. (12 Dec 1998) |
| hair cells | Mechanoreceptors located in the organ of corti that are sensitive to auditory stimuli and in the vestibular apparatus that are sensitive to movement of the head. In each case 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. (12 Dec 1998) |
| hair cells, inner | Bulbous cells that are medially placed in one row in the organ of corti. In contrast to the outer hair cells, the inner hair cells are fewer in number, have fewer sensory hairs, and are less differentiated. (12 Dec 1998) |
| hair cells, outer | Mechanoreceptors in the organ of corti. In mammals the outer hair cells are arranged in three rows which are further from the modiolus than the single row of inner hair cells. The motile properties of the outer hair cells may contribute actively to tuning the sensitivity and frequency selectivity of the cochlea. (12 Dec 1998) |
| hair cells, vestibular | Mechanoreceptors located in the acoustic maculae and the saemicircular canals that mediate the sense of balance, movement, and head position. The vestibular hair cells are connected to accessory structures in such a way that movements of the head displace their stereocilia. This influences the membrane potential of the cells which relay information about movements via the vestibular part of the acoustic nerve to the brainstem. (12 Dec 1998) |
| hairy cells | Medium sized leukocytes that have features of reticuloendothelial cell's and multiple cytoplasmic projections (hairs) on the cell surface, but which may be a variety of B lymphocyte; they are found in hairy cell leukaemia. (05 Mar 2000) |
| pregnancy cells | Hypophysial chromophobe cell's that increase in number and accumulate eosinophil granules during pregnancy. (05 Mar 2000) |
| pregranulosa cells | Capsular cell's surrounding the primordial ova in the embryonic ovary; they are derived from celomic epithelium. (05 Mar 2000) |
