CNS Full Form

Central Nervous System

Human bodies can’t function without the nervous system. Nervous system is known to be the complex network that tends to coordinate our actions, sensations along with reflexes. The nervous system is categorized into two categories namely, central nervous system (CNS) and peripheral nervous system (PNS).

The central nervous system is known to be the processing center of the body. The central nervous system consists of the brain as well as spinal cord. Both the brain and spinal cord are protected with the help of three layered membranes called meninges.

Grey and White matter

In the aspect of tissue, the central nervous system is categorized into two categories namely, grey matter as well as white matter. Grey matter is known to comprise neuron cell bodies along with their dendrites, glial cells as well as capillaries. Grey tissue receives an abundant supply of blood. This is the major reason behind the pink color of this tissue. Grey matter is found in the outer layers in the brain. On the other hand, grey matter forms a butterfly shape in the spinal cord. 

White matter is defined as the regions of the central nervous system which tend to host the majority of axons. Axons are known as long cords that extend from neurons. Most of the axons have a coating of myelin. Myelin is a white as well as fatty insulating cover that supports the nerve signals in traveling at a faster pace. White matter is known to be buried under the grey surface. On the other hand, white matter is known to be the external layer that surrounds the grey core in the spinal cord. 

The brain

If the central nervous system is known to be the processing center of the human body, then the brain is known to be its headquarters. The brain is categorized into three categories namely, the forebrain, the midbrain as well as the hindbrain. Forebrain is known to be the largest among them. Forebrain consists of the large outermost layer, cerebral cortex as well as small structures towards the center like thalamus, pineal gland and hypothalamus. 

The midbrain acts as a significant connection point between the forebrain as well as the hindbrain. The midbrain is known to be the top part of the brainstem. Brainstem tends to connect the brain to the spinal cord. 

The hindbrain is known to be the lowest back portion of the brain.

Parts of the brain

The cerebral cortex of the brain is known to be the outermost layer of the brain. It gives a wrinkly look to the brain. The cerebral cortex is categorized into two cerebral hemispheres. Each of the hemisphere is divided into four lobes namely frontal, parietal, temporal as well as occipital.
