Central Nervous System

The central nervous system (CNS) comprises the brain and spinal cord that complete it. The central nervous system is one half of the nervous system. The other part is called the peripheral nervous system, which consists of nerves that help to connect the brain and spinal cord to other parts of the body.

The central nervous system can be called the body's processing center.

Main Components of the Central Nervous System

• The brain

• The spinal cord

• The neurons

The brain 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.

Nervous System Diseases

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 problems in remembering, studying, or recalling. Most older people get these diseases as the nerves in their brains become weaker.

Steps to Keep Your Central Nervous System Healthy

• Exercise daily to stay fit and healthy

• Sleep for at least 7 hours to keep your brain calm

• Expose your body to sunlight to prevent multiple diseases

• Meditate regularly to keep your mind calm

• Walk barefoot on a clean floor

• Drink green tea every day to boost your mind

• Eat healthy, nutrient-rich food

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, thinking, and speech.

The five senses our brain controls are:

• Seeing

• Hearing

• Feeling

• Tasting

• Smelling

Peripheral Nervous System

The peripheral nervous system (PNS) is another part of the nervous system. It lies outside the brain and the spinal cord.

It plays a major role in passing information from different areas of the body back to the brain.

Signs of Nerve Damage

• Numbness or tingling in the hands and feet

• Feeling like you're wearing a tight glove or sock on your feet

Types of Nerves

• Motor Nerves

• Sensory Nerves

• Autonomic Nerves

• Cranial Nerves
