Circadian Rhythm
Cycles of metabolic
activity
and
behavior
that occur within a 24 h pattern. This daily rhythmicity includes hunger, wakefulness, and sleeping. Some
circadian rhythms
are influenced by the
cycle
of light and darkness throughout the year; however, when
humans
or
animals
are isolated from the outside
environment
circadian rhythms
remain fairly intact. The
mechanism
that
controls
circadian rhythm
is the
endogenous
biological clock
.
Cf.
infradian rhythm
,
ultradian rhythm
.
