- 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.
What is the functional system of the nervous system?
Functionally, the nervous system has two main subdivisions: the somatic, or voluntary, component;
and the autonomic, or involuntary, component

Which of the following are the functional parts 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 is nervous system with diagram?
The Central Nervous System is the integration and command center of the body. It consists of the brain, spinal cord and the retinas of the eyes. The Peripheral Nervous System consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect the central nervous system to arms, hands, legs and feet.
What is nervous system and its types?
The nervous system has two main parts: 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.
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 is a common disease of the nervous system?
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 is the most important part of the nervous system?
The brain and the spinal cord
make up the central nervous system. The nervous system is the most complex and highly organized body system. It receives information from the sensory organs via nerves, transmits the information through the spinal cord, and processes it in the brain.
What is nervous system and how it works?
What does the nervous system do? Your nervous system uses specialized cells called
neurons to send signals, or messages, all over your body
. These electrical signals travel between your brain, skin, organs, glands and muscles. The messages help you move your limbs and feel sensations, such as pain.
Which organ is part of our nervous system?
The brain and the spinal cord
are the central nervous system. The nerves that go through the whole body make up the peripheral nervous system.
