Melatonin is a hormone made by the pineal gland, a small gland in the brain. Melatonin helps control your sleep and wake cycles. Evaluate each statement below and select the statement that best describes the pathway. Select one: a. Light on the retina stimulates the hypothalamus to send a signal to the pineal gland to stop producing melatonin, signalling the body to go to sleep. b. Light on the retina stimulates the hypothalamus to send a signal to the pineal gland to increase the production of melatonin, signalling the body to go to sleep. c. Light on the retina stimulates the hypothalamus to send a signal to the pineal gland to stop producing melatonin, signalling the body to wake up. d. Light on the retina stimulates the hypothalamus to send a signal to the pineal gland to increase the production of melatonin, signalling the body to wake up
