Question

Quizplus · Accepted Answer

There are more than 100 different bodily processes that systematically vary over the course of each day, including blood pressure, the secretion of hormones, and pain sensitivity. This is due to circadian rhythms, which are regulated by the suprachiasmatic nucleus in the brain, not neurotransmitters like melatonin, serotonin, or dopamine. Sleep-wake schedules can affect circadian rhythms, causing disruptions such as jet lag.
