Difference between central nervous system and peripheral nervous system 0
Answers
1. NERVOUS SYSTEM 2. PERIPHERAL NERVOUS SYSTEM.
1.Central nervous system (CNS) consists of brain and spinal cord of the body.2. Peripheral nervous system (PNS) consists of dorsal and ventral root nerve cell heads, spinal and cranial nerves.
FUNCTION
1.Central nervous system (CNS) Controls all the voluntary functions of the body. 2.Peripheral nervous system (PNS) Controls and influences all the involuntary functions of the body.
NATURE
1.Central nervous system (CNS) is a system of sensory nerves and motor nerves linked with brain and spinal cord in a to and fro manner respectively. 2.Peripheral nervous system (PNS) is a vast system of dorsal and ventral root nerve cell heads and the network of spinal and cranial nerves that are linked to the brain and the spinal cord on one end and muscles on the other.
CONTROL
1.The main functions of the body are controlled by brain. 2.The PNS involuntarily control several functions of reasons like internal organs, blood vessels, smooth and cardiac muscles.
ROLE
1.The CNS Is connected to sensory receptors, muscles and glands in Peripheral parts of the body by the Peripheral nervous system.2. The sensory neurons contract nerve impulses from sensory receptors in various parts of the body to the central nervous system.
CONCLUSION
1.From the above discussion it is clear that the central nervous system (CNS) Controls the voluntary functions like walking, laughing, reading, etc. 2.Peripheral nervous system (PNS) is responsible for the involuntary actions like blinking of eye, heartbeat, digestion of food, etc.
