Etymology: Gk, phasis
1 pertaining to a process proceeding in stages or phases.
2 pertaining to a type of afferent or sensory nerve receptor of the proprioceptive system that responds to rate versus length changes in a muscle spindle. It is triggered by such stimuli as quick stretching, vibrations, and tapping.

phasic

The rapid contractions of the phasic portion permit it to generate more power than can be achieved by the slow contractions of the tonic muscle.

exotica occurs also in the rapidly adapting abdominal stretch receptors of crayfish (Nakajima and Onodera, 1969), which showed a phasic response with any intensity of applied electrical current.
In four studies, a mean over all recorded data spots of the phasic component of skin resistance or conductance is calculated; in one the mean over the tonic component.
Markers were used to determine specific phasic responses to the visual stimuli when viewing each food.
The tonic and phasic chin EMG activity was quantified manually in each patient.
1) of the phasic adductor muscle in a plane perpendicular to the hinge is greater in swimming monomyarians, presumably to increase the angular velocity of valve closure (Thayer 1972) and generate more powerful water jets (Yonge 1936, Thayer 1972, Soemodihardjo 1974).

Hence, may strongly be comparable to the Campnosperma-Cyrtostachys-Zalacca sub-association characteristic of transitional mangrove to shallow peats occurring before the vegetational succession of Phasic Community I (Anderson and Muller, 1975).
In a study conducted by Kawanaka et al6 about 103 consecutive patients were selected and hepatic venous waveforms were classified into four groups : type I, triphasic waveform; type II, biphasic waveform; type III, biphasic waveform with reduced phasic oscillations; and type IV, a flat waveform.
