Question

Quizplus · Accepted Answer

The suprachiasmatic nucleus is a small structure in the hypothalamus of the brain that is responsible for regulating the body's circadian rhythm, or biological clock. It receives information about light levels from the eyes and uses that information to synchronize various physiological processes with external environmental cues. The other structures listed, such as the hippocampus, amygdala, and cerebellum, are not directly involved in regulating the biological clock.
