The peripheral nervous system is itself classified into two systems: the somatic nervous system and the autonomic nervous system. Each system contains afferent and efferent components. The afferent arm consists of sensory (or afferent) neurons running from receptors for stimuli to the CNS.
The peripheral nervous system carries messages to and from the central nervous system. It sends information to the brain and carries out orders from the brain. Messages travel through the cranial nerves, those which branch out from the brain and go to many places in the head such as the ears, eyes and face.
Subsequently, What is the peripheral nervous system simple definition?
The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.
Also, What is a peripheral part of the body?
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.
How many peripheral nervous systems are there?
The peripheral nervous system itself is divided into two parts: the somatic nervous system and the autonomic nervous system. Each of these components plays a critical role in how the peripheral nervous system operates.

What is peripheral nervous system and its function?
The peripheral nervous system (PNS) is the division of the nervous system containing all the nerves that lie outside of the central nervous system (CNS). The primary role of the PNS is to connect the CNS to the organs, limbs, and skin.
What are the two types of peripheral nervous system?
– Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands.
– Somatic nervous system (SNS): Controls muscle movement and relays information from ears, eyes and skin to the central nervous system.
What body parts are in the peripheral nervous system?
The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.
What are the 2 functions of the peripheral nervous system?
The PNS consists of the nerves and ganglia outside the brain and spinal cord. The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body.
What is the peripheral nervous system and its functions?
The peripheral nervous system (PNS) is the division of the nervous system containing all the nerves that lie outside of the central nervous system (CNS). The primary role of the PNS is to connect the CNS to the organs, limbs, and skin.
How many types of peripheral nervous system are there?
Three types of peripheral nerves can be found within the two main areas of the peripheral nervous system: Sensory: Connects the brain and spinal cord to your skin and allow you to feel pain and other sensations. Autonomic: Controls involuntary function (e.g., blood pressure, digestion, heart rate).
What is Peripheral Nervous System Class 10?
The nervous system is the controlling system of the body and is composed of nerve cells and organs. The central nervous system comprises the brain and the spinal cord. … The peripheral nervous system comprises the network of nerves connected to the brain and the spinal cord.
What are the two functions of the peripheral nervous system?
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 are the main parts of the peripheral nervous system and their function?
Components Functions
—————————————————————————————————————————— ————————————————————————————————————————
*All the nerves in the body outside of the spinal cord and brain *Includes sensory cells, motor nerve cells, and somatic cells *Connects the central nervous system to the parts of the body *Relays information and responses *Controls body functions
What is the structure and function of the peripheral nervous system?
The peripheral nervous system consists of the nerves that branch out from the brain and spinal cord. These nerves form the communication network between the CNS and the body parts. The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system.
How do you explain the nervous system to a child?
The nervous system is the highway along which your brain sends and receives information about what is happening in the body and around it. This highway is made up of billions of nerve cells, or neurons (say new-rons) which join together to make nerves. A nerve is a fibre that sends impulses through the body.
What are the four parts of the peripheral nervous system?
The PNS is divided into the somatic and autonomic nervous systems. The somatic system controls voluntary activities, whereas the autonomic system controls involuntary activities. The autonomic nervous system is further divided into sympathetic, parasympathetic, and enteric divisions.
What is the function of the peripheral nerves?
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.
What is the main function of the peripheral nervous system quizlet?
The peripheral nervous system, or PNS, consists of the nerves and ganglia outside of the brain and the spinal cord. The main function of the PNS is to connect the central nervous system (CNS) to the limbs and organs. You just studied 2 terms!
What is the structure of the peripheral nervous system?
The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.
