Question

Quizplus · Accepted Answer

The suprachiasmatic nucleus plays a critical role in regulating circadian rhythms, which are biological processes that follow a daily cycle. The visual input to this nucleus, which comes from the retina, helps to synchronize the body's internal clock with external cues such as the level of light in the environment. Therefore, choice A is the best answer. Choices B, C, and D are all functions of other parts of the brain and are not directly related to the suprachiasmatic nucleus.
