What is CNS and PNS?
Our nervous system is divided in two components: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which encompasses nerves outside the brain and spinal cord.
What is the CNS an example of?
Central Nervous System (CNS) Definition
The central nervous system consists of the brain and spinal cord. The brain plays a central role in the control of most bodily functions, including awareness, movements, sensations, thoughts, speech, and memory.
How does the CNS work?
The brain and spinal cord (the CNS) function as the control center. They receive data and feedback from the sensory organs and from nerves throughout the body, process the information, and send commands back out. Nerve pathways of the PNS carry the incoming and outgoing signals.
What are CNS symptoms?

What is the main function of CNS?
The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.
What is difference between CNS and PNS?
The central nervous system or the CNS contains the brain and the spinal cord. All together, the brain and the spinal cord serve the nervous system’s command station. The peripheral nervous system or PNS contains the nerves, which leave the brain and the spinal cord and travel to certain areas of the body.
What are CNS disorders?
Specialty. Psychiatry, Neurology, Neurosurgery. Central nervous system diseases, also known as central nervous system disorders, are a group of neurological disorders that affect the structure or function of the brain or spinal cord, which collectively form the central nervous system (CNS).
What are the major parts of CNS?
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 are the top 3 common nervous system disorders?

What are the 5 main parts of the nervous system?
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
What are the 4 main functions of the nervous system?
The four main functions of the nervous system are:
- Control of body’s internal environment to maintain ‘homeostasis’ An example of this is the regulation of body temperature.
- Programming of spinal cord reflexes. An example of this is the stretch reflex.
- Memory and learning.
- Voluntary control of movement.
Is depression a CNS disorder?
Central nervous system — or CNS — depression happens when the body’s normal neurological functions slow down. It can result from substance overdoses, poisoning, or other medical conditions. Depression of the central nervous system or CNS often occurs when a person misuses a substance that slows brain activity.
