Every murderer knows they face life behind bars if they are caught and convicted. But only in a few rare cases does that really mean they will never taste freedom again â there are fewer than 50 people who have been told they will die in jail.
The human body is made up of trillions of cells. Cells of the nervous system, called nerve cells or neurons, are specialized to carry messages through an electrochemical process. The human brain has approximately 100 billion neurons.
The Nervous System. The human nervous system is broadly divided in to two sections, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is made up of the brain and the spinal cord. The PNS is made up of the nerves which radiate out from the spinal cord to the rest of the body.he Hindbrain. The hindbrain is thought to be the oldest part of the nervous system structure, and is made up of the cerebellum, the pons, and the medulla oblongata. The cerebellum is located underneath the cerebrum, and is primarily a center of movement control, regulation and coordination, and balance and posture.
