Central Nervous System and Peripheral Nervous System

Hello sir I want to know about Central Nervous System and Peripheral Nervous System so here can you please give me its details ?

[Kiran Chandar]

Hey as The central nervous system (CNS) is the part of the nervous system consisting of the brain and spinal cord. While The peripheral nervous system (PNS) is the part of the nervous system that consists of the nerves and ganglia on the outside of the brain and spinal cord.

Central Nervous System

The CNS is contained within the dorsal body cavity, with the brain housed in the cranial cavity and the spinal cord in the spinal canal.

In vertebrates, the brain is protected by the skull, while the spinal cord is protected by the vertebrae, both enclosed in the meanings

Peripheral Nervous System

The main function of the PNS is to connect the central nervous system (CNS) to the limbs and organs, essentially serving as a communication relay going back and forth between the brain and the extremities

Unlike the CNS, the PNS is not protected by the bone of spine and skull, or by the blood–brain barrier, which leaves it exposed to toxins and mechanical injuries.

The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system;

Parts

The Peripheral Nervous System (PNS):

Sensory receptors

Motor effectors.

The Central Nervous System (CNS):
