Circadian rhythm: cyclical changes that occur on a roughly 24-hour basis in many biological processes including hormone release, brain waves, body temperature, and drowsiness. Biological clock: term for the superchiasmatic nucleus (scn) in the hypothalamus that"s responsible for controlling our levels of alertness (feeling drowsy and want to take a nap) The urge to sleep is due to the levels of the hormone melatonin, which triggers feelings of sleepiness and increases after dark.
