Question

Quizplus · Accepted Answer

Melatonin is primarily involved in the regulation of circadian rhythms, acting as a signal to set the body's internal clock. It is secreted by the pineal gland in response to darkness and helps to regulate sleep-wake cycles.

Answer: B
 Melatonin may have a permissive action with glucorticoids, which means that it may enhance the effects of glucocorticoids in the body. This interaction may play a role in the regulation of immune function, inflammation, and stress response.

Answer: None
 Melatonin is not involved in the induction of calcium reabsorption or the stimulation of melanin pigment production. These actions are typically carried out by other hormones and signaling molecules in the body, such as parathyroid hormone and melanocyte-stimulating hormone, respectively.
