How will you differentiate the CNS and the PNS in terms of their functions?

The human body is the most complicated thing that has to be understood to know how and when a reaction in the body takes place. The nervous system is an important part of the body as it is responsible for its normal working. Show

There are several types of the nervous system in the body, and collectively they perform some functions such as, the nervous system sends messages to the body to control the internal bodily environment, it is responsible for reflexing of spinal cords, they also perform roles in memorizing and learning things, they are responsible for all of the voluntary movements, etc. The two main nervous systems are CNS and PNS that carry out most of the body functions. CNS vs PNSThe main difference between CNS and PNS is that both of them are responsible for different bodily functions. CNS majorly is responsible for organizing and analyzing messages or information received from different sensory organs and all of the voluntary functions, whereas PNS majorly is responsible for carrying out information to the CNS and conveying motor impulses to different organs. Damage to any nerve of the CNS will cause a major and global effect on the body while it will cause local effects on the body. Another main difference between both nervous systems is the regeneration process of nerves, which is not possible in CNS (in most cases) while it is possible in PNS (most of the nerves). Except these, they also differ in terms of components, nerve axons, etc. CNS or Central Nervous System is the system that has two components or is consists of the brain and spinal cord. It is said to be central due to its function of combining and receiving sensory information from the entire body. It is responsible for several functions of the body, which include walking, standing, running, etc. many nerves in this are incapable of regeneration. 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. Comparison Table Between CNS and PNSParameters of ComparisonCNSPNSFunctionControl voluntary functionsControl involuntary functionsComponentsBrain and spinal cordSensory receptors, sensory neurons, and motor neurons.Nerve AxonsSlender projectionsLong nerve fibersDamageCause global effectCause local effectRegeneration of Nerves Most are incapable of regeneration.Most are capable of regenerating.What is CNS?It consists of the brain (100 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 spinal Cord starts on the base and is protected by the vertebral column. It performs the functions that include PNS. It is composed of several components, they are:
It is divided into white (inner area of cortex) and gray matter (outer cortex). The following are also part of it:
Following are some of the diseases that can affect the Central Nervous System of an individual:
What is PNS?It is responsible for communication between CNS and organs by sending a sensory signal to the brain and provides a response to the body. It is composed of ganglia (neurons and neurons clusters). It can be divided into the following:
Following are some facts of PNS:
It is related to CNS also; therefore, if this nervous system is damaged due to any reason, it will affect CNS and body. Main Differences Between CNS and PNS
ConclusionTherefore, there should not be any difficulty in understanding the role and functions of the body. They can be misunderstood due to their similarities, such as both of them are part of the nervous system of vertebrates, they are responsible for giving response to the environmental stimuli, they comprise of neurons with same physiology. Any damage to them will affect the whole body, and it will be difficult for a person to perform simple things. The main difference between the central nervous system and peripheral nervous system is in their role and functions in the body. There are other nervous systems as well; they are Somatic Nervous System, Autonomic Nervous System, etc. they all are connected to CNS and PNS directly or indirectly. References

How will you differentiate the central nervous system and the peripheral in terms of their function?The central nervous system (CNS) 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 the difference between central nervous system and PNS?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 main function of CNS and PNS?Definition, Parts and Function
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.
