Central Nervous System(CNS ), Peripheral Nervous System

Central nervous system

The central nervous system, also called CNS in short form, comprises the brain and spinal cord that complete it. The central nervous system is the other half. Another part is called the peripheral nervous system. It consists of nerves that help to connect the brain and spinal cord to the other parts of the body. The central nervous system can be called the 'body's processing center.'

The three main components that are in the central nervous system are: 

  1. The brain
  2. The spinal cord
  3. The neurons 

The brain is what controls all the functions of the body, including the way we act. The spinal cord contains threadlike nerves that branch out to every organ and body part to create a connection. The network of nerves passes all the messages and electric impulses back and forth from the brain to all the body's different organs.

Some of the nervous system diseases are:

  • Alzheimer's disease.
  • Bell's palsy.
  • Cerebral palsy.
  • Epilepsy. 
  • Motor neuron disease.
  • Multiple sclerosis.
  • Neurofibromatosis.
  • Parkinson's disease.

These diseases cause many problems in remembering, studying, or recalling. Most old people get these diseases as the nerves of their brains to get weaker.

The simple steps to keep our central nervous system healthy are:

Steps to keep your central nervous system healthy

  1. Properly exercise daily to stay fit and healthy. 
  2. Sleep for at least 7 hours to keep your brain calm. 
  3. Try to expose your body to sunlight to prevent multiple diseases.
  4. Meditate regularly to keep your mind calm.
  5. Try to walk barefoot on a clean floor. 
  6. Drink green tea every day that boosts your mind.
  7. Eat food that is healthy for your body and provides nutrients.

The central nervous system is the body's processing center, where the brain processes and controls our entire body. 

The brain controls most of the body's functions, such as awareness, movement of organs, how we think, and what we say.

The five senses our brain control are seeing, hearing, feeling, tasting, and smelling. 

Peripheral nervous system

Your peripheral nervous system is another part of the brain. It is a different part of our nervous system. It lies outside our brain and the spinal cord. It plays a great role in passing information from different areas of our body back to our brains.

The signs that the nerve has been damaged are

  1. Numbness or tingling in the hands and feet of a person.
  2. Feeling like you're wearing a tight glove or sock on your feet.

The four types of nerves are:

  1. Motor Nerves.
  2. Sensory Nerves.
  3. Autonomic Nerves. 
  4. Cranial Nerves.
