What are the components of central nervous system?
The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
How are the components of central nervous system protected class 10?
First, the entire CNS is enclosed in bone. The brain is protected by the skull, while the spinal cord is protected by the vertebra of the spinal column. The brain and spinal cord are both covered with a protective tissue known as meninges.
What are the 3 components of the nervous system?
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
What are the components of CNS and PNS?
The central nervous system includes the brain and spinal cord, while the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs.
What are the top 3 common nervous system disorders?
Brain and nervous system problems are common. These neurological disorders include multiple sclerosis, Alzheimer’s disease, Parkinson’s disease, epilepsy, and stroke, and can affect memory and ability to perform daily activities.
What are the 3 functions of the central nervous system?
The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions: sensory input, information processing, and motor output.
What happens if the central nervous system is damaged?

What is CNS mean?

What is the main function of nervous system?
The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.
What is the purpose structure and function of the central nervous system?
The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.
What organs are in nervous system?
The anatomy of the nervous system in humans consists of the brain and spinal cord, along with the primary sense organs and all the nerves associated with these organs. The brain and the spinal cord form the central nervous system (CNS).
What is the relationship between CNS and PNS?
If the central nervous system is the command centre of the body, the peripheral nervous system (PNS) represents the front line. The PNS links the CNS to the body’s sense receptors, muscles, and glands.
How do CNS and PNS work together?
The PNS and CNS work together to send information between the brain and the rest of the body. Nerves emerge from the CNS through the skull and vertebral column, using the PNS to carry information to the rest of the body. The PNS is made up of two divisions – sensory and motor.
What are the four major components of the central nervous system?
Central Nervous System (CNS) Definition
