Question

Quizplus · Accepted Answer

The pineal gland is responsible for the secretion of melatonin, which is involved in regulating sleep-wake cycles and circadian rhythms.

Answer: B
 The suprachiasmatic nucleus is a region in the hypothalamus that regulates the body's internal clock and helps to maintain wakefulness and alertness during the day.

Answer: D
 The reticular formation is a network of nerve cells in the brainstem that is responsible for regulating sleep and arousal, among other functions. It does not sense light directly, but it receives input from the eyes and other sensory organs to help modulate wakefulness and attention.

C) is incorrect because retinal ganglion cells are specialized neurons in the retina that transmit visual information to the brain, and are not involved in regulating the pineal gland.
