What is parasympathetic nervous system?
The parasympathetic nervous system predominates in quiet “rest and digest” conditions while the sympathetic nervous system drives the “fight or flight” response in stressful situations. The main purpose of the PNS is to conserve energy to be used later and to regulate bodily functions like digestion and urination.[1]
What are the two parts of peripheral nervous system?
The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system.
What is the function of PNS?
Peripheral nerves reside outside your brain and spinal cord. They relay information between your brain and the rest of your body. The peripheral nervous system is divided into two main parts: Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands.
How does the PNS work?
The peripheral system allows the brain and spinal cord to receive and send information to other areas of the body, which allows us to react to stimuli in our environment. The nerves that make up the peripheral nervous system are actually the axons or bundles of axons from nerve cells or neurons.
What does peripheral mean in anatomy?
away from the center
Peripheral means “away from the center.” It refers to areas away from the center of the body or a body part. For example, the hands are peripheral to the shoulder. The toes are peripheral to the knees.
What are the functions of the peripheral nervous system?
The main function of the peripheral nervous system (PNS) is to connect the central nervous system (CNS) to the rest of the body, such as the organs, muscles and limbs. The PNS is made up of nerves and neurons that connect the nervous system to the various parts of the body, which allows the brain to communicate with all areas of the body.
What is the difference between the central nervous system and the peripheral?
The key difference between central and peripheral nervous system is that the central nervous system includes the brain and the 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 peripheral nervous system made up of?
The peripheral nervous system is made up of the nerve fibers that branch off from the spinal cord and extend to all parts of the body, including the neck and arms, torso, legs, skeletal muscles and internal organs.
What is an example of a peripheral nervous system?
For example, motor neurons (efferent neurons) contact the skeletal muscles to execute the voluntary movement of raising your arm and wiggling your hand about. Peripheral nervous system nerves often extend a great length from the central nervous system to reach the periphery of the body.
