| alabama period | <geology> A period in the American eocene, the lowest in the tertiary age except the lignitic. Source: Websters Dictionary (01 Mar 1998) |
| anaesthesia recovery period | The period of emergence from general anaesthesia, where different elements of consciousness return at different rates. (12 Dec 1998) |
| Gap1 period | The period of the cell cycle after cell division when there is synthesis of RNA and protein; it may last for a few hours in rapidly growing tissue or a lifetime in non-renewing cells such as nerve cells. Synonym: Gap1 phase, postmitotic phase. (05 Mar 2000) |
| Gap2 period | The period in the cell cycle when synthesis of DNA is completed but before mitosis begins. Synonym: Gap2 phase, premitotic phase. (05 Mar 2000) |
| masticatory silent period | A pause in electromyographic patterns associated with tooth contacts during chewing and biting; a part of the complex feedback mechanism of mandibular control involving receptors in the periodontal ligament and muscles. (05 Mar 2000) |
| vulnerable period | Vulnerable period of heart, a brief time during the cardiac cycle when stimuli are particularly likely to induce repetitive activity like tachycardia, flutter, or fibrillation which persists after the stimulus has ceased; for the ventricle, it occurs during the latter part of systole, during the relative refractory period coincident with the inscription of the latter half of the T wave of the electrocardiogram. (05 Mar 2000) |
| menstrual period | <medicine> The catamenial or menstrual discharge, a periodic flow of blood or bloody fluid from the uterus or female generative organs. Origin: L. Mensis month, pl. Menses months, and the monthly courses of women. Cf. Month. Source: Websters Dictionary (01 Mar 1998) |

| Wenckebach period | A sequence of cardiac cycles in the electrocardiogram ending in a dropped beat due to A-V block, the preceding cycles showing progressively lengthening P-R intervals; the P-R interval following the dropped beat is again shortened. (05 Mar 2000) |
| crisis period | A situation in which most of the secondary cells in a culture die off, even though conditions exist which should normally be favorable for their growth. (09 Oct 1997) |
