| resting | <botany> From Rest, Resting spore, a spore in certain orders of algae, which remains quiescent, retaining its vitality, for long periods of time. Source: Websters Dictionary (01 Mar 1998) |
| resting length | The length at rest from which a muscle develops maximum isometric tension. (05 Mar 2000) |
| resting phase | More appropriately called interphase. The interval in the cell cycle between two cell divisions when the individual chromosomes cannot be distinguished, interphase was once thought to be the resting phase but it is far from a time of rest for the cell. It is the time when DNA is replicated in the cell nucleus. (12 Dec 1998) |
| resting potential | <physiology> The electrical potential of the inside of a cell, relative to its surroundings. Almost all animal cells are negative inside, resting potentials are in the range 20 to 100mV, 70mV typical. Resting potentials reflect the action of the sodium pump only indirectly, they are mainly caused by the subsequent diffusion of potassium out of the cell through potassium leak channels. The resting potential is thus close to the Nernst potential for potassium. See: action potential. (10 Mar 1998) |
| resting saliva | The saliva found in the mouth in the intervals of food taking and mastication. (05 Mar 2000) |
| resting stage | The quiescent stage of a cell or its nucleus in which no karyokinetic changes are taking place. Synonym: vegetative stage. (05 Mar 2000) |
| resting tidal volume | The tidal volume under normal conditions, i.e., in the absence of exercise or other conditions that stimulate breathing. (05 Mar 2000) |
| resting tremor | A coarse, rhythmic tremor, 3-5 Hz frequency, usually confined to hands and forearms, that appears when the limbs are relaxed, and disappears with active limb movements; characteristic of Parkinson disease. Synonym: passive tremor. (05 Mar 2000) |
| phase, resting | More appropriately called interphase. The interval in the cell cycle between two cell divisions when the individual chromosomes cannot be distinguished, interphase was once thought to be the resting phase but it is far from a time of rest for the cell. It is the time when DNA is replicated in the cell nucleus. (12 Dec 1998) |
| T-cell-rich, B-cell lymphoma | <tumour> A B-cell lymphoma in which more than 90% of the cells are of T-cell origin, masking the large cells that form the neoplastic B-cell component. See: adult T-cell lymphoma. (05 Mar 2000) |
| absorption cell | A small glass chamber with parallel sides, in which absorption spectra of solutions can be obtained. (05 Mar 2000) |
| acid cell | One of the cell's of the gastric glands; it lies upon the basement membrane, covered by the chief cell's, and secretes hydrochloric acid that reaches the lumen of the gland through fine intracellular and intercellular canals (canaliculi). Synonym: acid cell, oxyntic cell. (05 Mar 2000) |
| acidophil cell | A cell whose cytoplasm or its granules stain with acid dyes. (05 Mar 2000) |
| acinar cell | Any secreting cell lining an acinus, especially applied to the cell's of the pancreas that furnish pancreatic juice and enzymes to distinguish them from the cell's of ducts and the islets of Langerhans. Synonym: acinous cell. (05 Mar 2000) |
