What is the central and peripheral nervous system?

What is the difference between central nervous system and peripheral nervous system?

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 is part of the peripheral nervous system?

The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.

What is the central nervous system?

Broadly speaking, the nervous system is organised into two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is the processing centre of the body and consists of the brain and the spinal cord. Both of these are protected by three layers of membranes known as meninges.

The PNS connects the CNS to the rest of the body. The primary function of the peripheral nervous system is to connect the brain and spinal cord to the rest of the body and the external environment. The peripheral nervous system transmits information to and from the CNS.

What is the main function of PNS?

The PNS has three basic functions: (1) conveying motor commands to all voluntary striated muscles in the body; (2) carrying sensory information about the external world and the body to the brain and spinal cord (except visual information: the optic nerves, which convey information from the retina to the brain, are in …

What is the central nervous system made up of?

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 are the two main parts of the central nervous system?

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 is the center of your brain called?

The brainstem (middle of brain) connects the cerebrum with the spinal cord. The brainstem includes the midbrain, the pons and the medulla.

What is an example of the peripheral nervous system?

When a bright light is suddenly turned on, sensory receptors in the eye communicate this to the CNS. The PNS mediates the response to this stimulus. The pupils contract and the external eye muscles squint.
