Central Nervous System
The central nervous system (CNS) consists of the brain in the skull and the spinal cord, which threads through holes down the middle of the vertebrae. The Central Nervous System has hundred billions of neurons which work by tolerating, engendering and transmitting electrochemical driving forces. The central nervous system has been thoroughly studied by anatomists and physiologists, but it still holds many secrets; it controls our thoughts, movements, emotions, and desires. It also controls our breathing, heart rate, the release of some hormones, body temperature, and much more.
