| RVF | renal vascular failure; Rift Valley fever; right ventricular failure; right visual field |
|---|---|
| RVS | rectovaginal space; relative value scale/study; reported visual sensation; retrovaginal space |
| STVS | short-term visual storage |
| VAcc | visual acuity with correction |
| VALE | visual acuity, left eye |
| amniogenic cells | Cell's from which the amnion develops. (05 Mar 2000) |
|---|---|
| anabiotic cells | Cell's that are capable of resuscitation after apparent death; the existence of anabiotic tumour cell's is postulated to explain the recurrence of a cancer after a very long symptomless period following operation. (05 Mar 2000) |
| angioblastic cells | Those cell's in the early embryo from which primitive blood cell's and endothelium develop. (05 Mar 2000) |
| anterior cells | The anterior group of air cells of the ethmoidal sinus's; each sinus communicates with the middle meatus of the nasal cavity. Synonym: sinus ethmoidales anteriores, anterior cells, anterior sinuses, cellulae anteriores. (05 Mar 2000) |
| anterior ethmoidal air cells | The anterior group of air cells of the ethmoidal sinus's; each sinus communicates with the middle meatus of the nasal cavity. Synonym: sinus ethmoidales anteriores, anterior cells, anterior sinuses, cellulae anteriores. (05 Mar 2000) |
| anterior horn cells | Motor neurons in the anterior (ventral) horn of the spinal cord which project to skeletal muscles. (12 Dec 1998) |
| antibody-producing cells | Cells of the lymphoid series that can react with antigen to produce specific cell products called antibodies. Various cell subpopulations, often B-lymphocytes, can be defined, based on the different classes of immunoglobulins that they synthesise. (12 Dec 1998) |
| antigen-presenting cells | Immunocompetent cells, usually ia positive, that mediate the cellular immune response by processing and presenting antigens or mitogens which stimulate T-cell activation. (12 Dec 1998) |
| apud cells | Cells derived from primitive cell types in the neural crest. During ontogeny they migrate to the foregut and specific locations of the neuroendocrine system. Properly located these cells form part of the normal hormone producing tissues of the neuroendocrine system. If misdirected these cells may become hyperplastic, adenomatous, or malignant (cf. Apudoma). (12 Dec 1998) |
| argentaffin cells | Cell's that contain granules which precipitate silver from an ammoniacal silver nitrate solution. See: enteroendocrine cells. (05 Mar 2000) |
| basal cells | Small, round cells found in the lower part, or base, of the epidermis, the outer layer of the skin. (12 Dec 1998) |
| B-cells | A type of white blood cell. Many B-cells mature into plasma cells, which can produce antibody proteins necessary to fight off infections, such as viruses. (12 Dec 1998) |
| Berger 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) |
| Betz cells | Large pyramidal cell's in the motor area of the precentral gyrus of the cerebral cortex. Synonym: Bevan-Lewis cells. (05 Mar 2000) |
| Bevan-Lewis cells | Large pyramidal cell's in the motor area of the precentral gyrus of the cerebral cortex. Synonym: Bevan-Lewis cells. (05 Mar 2000) |
