| 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 cell | A quiescent cell; one not undergoing mitosis. (05 Mar 2000) |
| 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) |
| resting wandering cell | A relatively immotile macrophage found in connective tissue, lymph nodes, spleen, and bone marrow. Synonym: resting wandering cell. (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) |
| maximal expiratory flow rate | <chest medicine, physiology> Measurement of rate of airflow during the first liter expired after the first 200 ml have been exhausted during a forced vital capacity determination. Common abbreviations are MEFR, FEF 202-1200, and fef 0.2-1.2. Acronym: MEFR (21 Jun 2000) |
| maximal expiratory flow-volume curve | <chest medicine> Curves depicting maximal expiratory flow in liters/second at each point of lung inflation (expressed in liters or percentage of forced vital capacity) during a forced vital capacity determination. Common abbreviation is mefv. (12 Dec 1998) |
| peak expiratory flow | The maximum flow at the outset of forced expiration, which is reduced in proportion to the severity of airway obstruction, as in asthma. (05 Mar 2000) |
| peak expiratory flow rate | Measurement of the maximum rate of airflow attained during a forced vital capacity determination. Common abbreviations are pefr and pfr. (12 Dec 1998) |
