What is the Nervous System? its function and Parts of the Human Nervous System


What is the nervous system?

The nervous system is made up of a complex network of specialized neurons that transmit information. When we progress up the food chain, the nervous system becomes more complex. The nervous system is a part of the body that transmits information across the body. It enables animals to adjust to their environment. The central nervous system is made up of the cortex, spinal cord, and nerves. It can be found in almost any animal or plant. Its aim is to coordinate movement and process information from the senses.

For example, synergists such as jellyfish have relatively simple neural nets throughout the body. Crabs have a more complex nervous system in the form of 2 nerve centers.


The nervous system in the human body directs stimulus-based organ movements that identify and transfer neurons. They send signals in the form of electrical impulses that are received by the senses. The senses, muscles, spinal cord, and brain all play a role in neural coordination.


The human nervous system, one of the most complex organs ever developed, has two parts:


Nervous System 



  • Central nervous system (contains the brain and spinal cord)
  • Peripheral nervous system (includes all veins in the body)

Central nervous system

The central nervous system (CNS) is often referred to as the body’s central processing unit. It contains the brain and spinal cord.

 

The brain

The brain is one of the most important, large, and central organs in the human nervous system. It is the control unit of the nervous system, which helps to discover, remember, understand and make new things. It wraps around the inside of the skull and provides anterior, lateral, and dorsal protection.
