During the day,superchiasmatic nuclei help to raise the body's temperature and increase alertness by reducing the pineal gland's secretion of ______.

Question

Quizplus · Accepted Answer

The production of melatonin by the pineal gland is inhibited by the superchiasmatic nuclei during the day. Melatonin secretion is associated with sleepiness and a lower body temperature, so reducing its secretion helps to raise the body's temperature and increase alertness. Endorphins and neurotransmitter molecules are not directly related to the regulation of circadian rhythms, and "antagonistic molecules" is not a specific term in this context.
