What does the central nervous system contains?
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 central nervous system in psychology?
The central nervous system (CNS) is comprised of the brain and spinal cord. The CNS receives sensory information from the nervous system and controls the body’s responses.
What does the central and peripheral nervous system do?
These nerves extend from the central nervous system to the outermost areas of the body. The peripheral system allows the brain and spinal cord to receive and send information to other areas of the body, which allows us to react to stimuli in our environment.
What is difference between PNS and CNS?
The CNS includes the brain and spinal cord. The brain is the body’s “control center.” The CNS has various centers located within it that carry out the sensory, motor and integration of data. The PNS is a vast network of spinal and cranial nerves that are linked to the brain and the spinal cord.
What are the major components of the central nervous system?
Structure of the Central Nervous System. The CNS is comprised of the brain, brain stem, and spinal cord. The central nervous system: The three major components of the central nervous system: 1) the brain, 2) brain stem, and 3) spinal cord.
What are two main divisions of the central nervous system?
The nervous system of vertebrates has two main divisions: the central nervous system, consisting of the brain and spinal cord, and the peripheral nervous system, which in humans includes 12 pairs of cranial nerves, 31 pairs of spinal nerves, and the autonomic, or involuntary, nervous system.
What happens if the central nervous system is damaged?
When an injury to the central nervous system occurs, the soft tissue of the brain and spinal cord swells, causing pressure because of the confined space. The swelling makes the injury worse unless it is rapidly relieved. Fractured bones can lead to further damage and the possibility of infection.
What do narcotics do to the central nervous system?
Narcotic drugs work as central nervous system (CNS) depressants by slowing down neural activity in both the brain and the body. The brain and spinal cord make up the two main organs in the CNS.
