What is internal clock in human body?

In vertebrate animals, including humans, the master clock is a group of about 20,000 nerve cells (neurons) that form a structure called the suprachiasmatic nucleus, or SCN. The SCN is in a part of the brain called the hypothalamus and receives direct input from the eyes. Circadian rhythm cycle of a typical teenager.

Does the human body have a clock?

The Biological Clock
Every cell in our bodies has its very own clock. Unlike the clocks we are used to, the clocks in our cells have no cogs or gears: they are biological. Our biological clocks keep near perfect time with the 24-h cycle of light and dark on Earth. We call this regular daily cycle the circadian rhythm.

What hormone controls the body clock?

Melatonin
Melatonin is an important hormone in circadian synchronization. This hormone is involved in many biological and physiological regulations in the body. It is an effective hormone for human biorhythm (circadian rhythm). The main role of this hormone is to maintain the biological clock and to adjust the body rhythm [25].
