What is the difference between cns and pns

It is responsible for several functions of the body, which include walking, standing, running, etc. PNS, or Peripheral Nervous System, is the system that plays an important role in conveying messages and information to the central nervous system. Therefore it is important for carrying out involuntary functions and activities in the body. The involuntary function includes that body performs without intentions, such as breathing, sensing, hurting, etc.

It consists of the brain billion nerve cells and the spinal cord. Cells are protected by meninges and the skull. It can be divided into four lobes: parietal responsible for sensory information , temporal memory and learning purposes , occipital receives visuals , and frontal responsible for voluntary movements.

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.

Each part of the system plays a vital role in how information is communicated throughout the body. The peripheral nervous system PNS is the division of the nervous system containing all the nerves that lie outside of the central nervous system CNS. CNS is the Central Nervous System that functions in order to coordinate each and every activity taking place in all the parts of the body of every bilaterian organism animals evolved to a better organic stage than sponges and jellyfish.

The central nervous system, in vertebrates is placed inside the meninges and consists of the brain and the spinal cord. On the other hand the main function of the Peripheral Nervous System is to connect the Central Nervous System with the various organs in the body and the limbs.

The Central Nervous System is placed safely within the dorsal cavity, the brain placed inside the cranial cavity and the spinal cord in the spinal cavity.

The skull protects the brain and the vertebra protects the entire spinal cord. It remains open to all sorts of mechanical injuries and toxins as well. It consists of the autonomic nervous system and the somatic nervous system. The function of the Peripheral Nervous System is to integrate important information and details that are gathered from the external environment.
