CENTRAL NERVOUS SYSTEM
Spinal cord and Brain are the integrating centers of the Nervous system. The central nervous system is divided into spinal cord and brain.
It is the part of central nervous system which is enclosed within the skull. The brain is divided into three parts FORE BRAIN, MID BRAIN and CEREBRAL BRAIN.
-It consist of the Cerebrum which is concerned with personality, ability to plan and organize, motor function, including vocalization of speech (Frontal Lobe); sensation of touch (Parietal lobe); memory, fear, comprehension of speech (Temporal lobe) and vision (Occipital lobe).
-It forms a large part of reticular activating system which filters the sensory inputs and acts as a selective relay allowing only selected sensory information to reach the fore brain. Something to know about this mid brain is that it is very small.
-It consists of the medulla and the cerebellum. The medulla controls things such as breathing whereas the Cerebellum coordinates muscular activities such as doing some movements and balance.
THE SPINAL CORD
It is the part of central nervous system which extends from the base of the brain to the hips. Its cells are found in the center and bundles of axons surround the cell bodies around the outside. The spinal cord is protected by the vertebral of the spine.
The cell bodies of the spinal cord includes motor neuron and neuron cells. The material which is used to communicate with the brain it are known as Axons.
