THE SUPRACHIASMATIC NUCLEI AND THE PINEAL GLAND. Most human bodily functions and behaviours are not âsteady-stateâ. Instead, they fluctuate in 24-hour cycles, such as the sleeping and waking cycle and the cycles for body temperature, hunger, and the secretion of various hormones.
The pineal gland secretes the hormone melatonin which controls the body's biological clock. It is a small gland situated deep within the brain, just below the back of the corpus callosum. Credit: PASIEKA/Science Photo Library/Getty Images.
