Answer:
The correct answer is Suprachiasmatic nucleus
Explanation:
Melatonin is a hormone secreted by the pineal gland which plays a major role in sleep regulation in humans. This hormone is majorly secreted at the night time when the light entry reduces in eyes.
The Suprachiasmatic nucleus of the anterior hypothalamus regulates the release of melatonin by the pineal gland in the night by getting the low light signal from the optic nerves. By controlling the secretion of melatonin Suprachiasmatic nucleus controls the sleep-wake cycle in humans. So the correct answer is the Suprachiasmatic nucleus.
Question:
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. neural control, because the brain sends the signal to release melatonin through nerve cells
B. muscular control, because the muscles can be used to control the release of melatonin
C. endocrine control, because melatonin is secreted into the blood and regulates body processes
D. cardiovascular control, because melatonin flows through the blood to deliver the message
Answer:
C. endocrine control, because melatonin is secreted into the blood and regulates body processes
