Theincludes the brain and spinal cord. it includes inputs, outputs and interneurons. it also includes non-neuronal cells like glia and blood vessels.

Central Nervous System

Explanation:

The Central Nervous System (CNS) comprises of the Brain and the Spinal cord. IT involves in assembling information from all over the body and harmonizes various roles and activity. The Brain plays a major central and integral role in the coordination of most bodily functions such as  locomotion, speech, thoughts, memory etc.

Inputs of information as stimuli or signals are processed to the brain through the afferent neurons, the pathway these signals follows is the interneurons and the feedback response is relayed to the targeted areas via the efferent neurons.

The Central nervous system also consist of Non-neuronal cells such as they glia cells whose main function  is to provide homeostatsis(maintaining the internal environment), formation of the myelin( lipid fats that surronds the axon of the nerve cells) and to provide support, protect and proffers firmness to the neurons in the Central Nervous System.
