What are 2 functions of the nervous system?
First, the basic functions of the nervous system are sensation, integration, and response . Secondly, control of the body can be somatic or autonomic—divisions that are largely defined by the structures that are involved in the response.
What are the 3 functions of the central nervous system?
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 the main 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.
What is the main organ of the 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.
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 an example of the central nervous system?
The central nervous system (CNS) includes the nerves in the brain and spinal cord . ... It can also send signals in the other direction – from the body to the brain – providing your brain with information about how full your bladder is or how quickly your heart is beating, for example.
What organs are in nervous system?
The brain and spinal cord are the organs of the central nervous system.

The brain is in the cranial vault, and the spinal cord is in the vertebral canal of the vertebral column.
What is nervous system and its types?
The nervous system includes both the Central nervous system and Peripheral nervous system . The central nervous system is made up of the brain and spinal cord, and the peripheral nervous system is made up of the Somatic and the Autonomic nervous systems.
How many nervous system do we have in our body?
As with other higher vertebrates, the human nervous system has two main parts : the central nervous system (the brain and spinal cord) and the peripheral nervous system (the nerves that carry impulses to and from the central nervous system).
