The multi-polar neurones are neither sensory nor motor but make connections to other neurons inside the central nervous system (3). The Central Nervous System (CNS) is composed of the brain and spinal cord. It acts as the coordinator of the nervous system. It comprises a long, approximately cylindrical structure - the spinal cord - and its anterior expansion - the brain (1).

The nerve cells connect to the brain through the...
