Melatonin is a molecule that is produced in the pineal gland and secreted into the blood. Melatonin then travels to different parts of the brain. It causes drowsiness and decreases body temperature to assist in the regulation of the sleep/wake cycle. What kind of control is used to regulate this molecule?

A.
endocrine control, because melatonin is secreted into the blood and regulates body processes
B.
cardiovascular control, because melatonin flows through the blood to deliver the message
C.
muscular control, because the muscles can be used to control the release of melatonin
D.
neural control, because the brain sends the signal to release melatonin through nerve cells

The correct answer is A. Endocrine control, because melatonin is secreted into the blood and regulates body processes. Melatonin is produced in the pineal gland and is released into the bloodstream, where it travels to various parts of the brain to regulate the sleep/wake cycle. As a hormone, melatonin is part of the endocrine system and is regulated by feedback mechanisms that maintain its levels within a certain range.
