Circadian Rhythm

Circadian Rhythm is the regular recurrence, in cycles of about 24 hours, of biological processes or activities, such as sensitivity to drugs and stimuli, hormone secretion, sleeping, feeding, etc. This rhythm seems to be set by a 'biological clock' which seems to be set by recurring daylight and darkness.
How Does the Suprachiasmatic Nucleus (SCN) Control Circadian Rhythm?

Circadian rhythms are biological cycles within organisms that allow them to adjust their physiology and behavior to anticipate and adapt to changes in the outside environment. Circadian rhythms are maintained with the help of circadian clocks, the main circadian clock in mammals is the suprachiasmatic nucleus (SCN).
