| effective refractory period | The period during which impulses may appear but are too weak to be conducted; the longest interval between adequate stimuli, falling just short of the time necessary to allow a propagated response to be evoked in a tissue by the second stimulus; it differs from the functional refractory period in that it is a measure of stimulus interval rather than response interval of time.

| ejection period | The period in the cardiac cycle when the semilunar valves are open and blood is being ejected from the ventricles into the arterial system. Synonym: ejection period. (05 Mar 2000) |
| total refractory period | The absolute refractory period plus the relative refractory period. (05 Mar 2000) |
| trenton period | <geology> A subdivision in the lower Silurian system of America; so named from Trenton Falls, in new York. The rocks are mostly limestones, and the period is divided into the Trenton, Utica, and Cincinnati epochs. Source: Websters Dictionary (01 Mar 1998) |
| extrinsic incubation period | Time required for the development of a disease agent in a vector, from the time of uptake of the agent to the time when the vector is infective. (05 Mar 2000) |
| fertile period | The period in a regularly menstruating woman's cycle, during which conception is most likely. (05 Mar 2000) |
| latent period | A seemingly inactive period, as that between exposure of tissue to an injurious agent and the manifestation of response or that between the instant of stimulation and the beginning of response. (18 Nov 1997) |
| functional refractory period | The minimum interval possible between successive responses to stimulation of a tissue. (05 Mar 2000) |
