| G0 | quiescent phase of cells leaving the mitotic cycle |
| 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) |
| cytomegalic cells | Cell's containing large intranuclear and intracytoplasmic cytomegalic inclusion bodies caused by cytomegalovirus; a member of the family Herpesviridae. (05 Mar 2000) |
| cytotrophoblastic cells | Stem cell's that fuse to form the overlying syncytiotrophoblast of placental villi. Synonym: Langhans' cells. (05 Mar 2000) |
| heart failure cells | Macrophages in the lung during left heart failure that often carry large amounts of haemosiderin. See: siderophore. (05 Mar 2000) |
| prokaryotic cells | Cells, such as those of bacteria and the blue green algae, which lack a nuclear membrane so that the nuclear material is either scattered in the cytoplasm or collected in a nucleoid region. (12 Dec 1998) |
| HEMPAS cells | The abnormal erythrocytes of type II congenital dyserythropoietic anaemia. See: HEMPAS. (05 Mar 2000) |
| satellite cells | Neuroglial cell's surrounding the cell body of a ganglion cell in the spinal, cranial, and autonomic ganglia. (05 Mar 2000) |
| Schultze's cells | Very slender nerve cell's, with large nuclei and surmounted by six to eight long, sensitive cilia in the olfactory epithelium at the roof of the nose; they are the receptors for smell. Synonym: olfactory cells, Schultze's cells. (05 Mar 2000) |
| schwann cells | Neuroglial cells of the peripheral nervous system which form the insulating myelin sheaths of peripheral axons. (12 Dec 1998) |
| hilus cells | Cell's in the hilus of the ovary that produce androgens; they are thought to be the ovarian counterpart of the interstitial cell's of the testis. Synonym: Berger cells. (05 Mar 2000) |
| hobnail cells | Cell's characteristic of a mesonephroma; a round expansion of clear cytoplasm projects into the lumen of neoplastic tubules, but the basal part of the cell containing the nucleus is narrow. (05 Mar 2000) |
