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 brain is composed of many types of cells, but the functional unit is called the Neurons. All sensations, movements, thoughts, memories, and feelings are the result of signals that pass through neurons. The other cells in the brain are the glial cells, which have important roles in the functioning of the neuron.he brain is composed of many types of cells, but the functional unit is called the Neurons.
