The Endocrine System
Melanogenisis is the activity that controls melanocytes. Melanocytes are the cells in the human body that produce melanin, the pigmentation found in eyes and skin.
The activity of all human body systems is coordinated by the nervous system. It regulates and controls various bodily functions through the transmission of electrochemical signals between the brain, spinal cord, and peripheral nerves. This allows for communication and coordination between different parts of the body to maintain homeostasis.

When the human body temperature is not regulated, metabolic reactions can become impaired. Elevated temperatures can lead to increased enzyme activity initially, but if temperatures rise too high, it can denature enzymes and disrupt metabolic processes. Conversely, low temperatures can slow down enzymatic activity, resulting in decreased metabolic rates. Both extremes can negatively affect overall physiological functions and homeostasis.

The 'nucleus' is what controls the cell in a human or animal system of body.

The Central Nervous System is the master system of the body and practically controls all other systems.
