Introduction To What Peripheral Nervous System
Peripheral Nervous System – Location:
The peripheral nervous system (PNS) is a part of the nervous system that consists of the nerves and ganglia outside of the brain and spinal cord. The PNS is divided into the autonomic nervous system (ANS) and the somatic nervous system. The autonomic nervous system is responsible for controlling the body’s involuntary functions, such as heart rate, digestion, and sweating. The somatic nervous system is responsible for controlling the body’s voluntary functions, such as movement and sensation.
Peripheral Nervous System Location
The peripheral nervous system is located outside of the central nervous system. It includes the autonomic nervous system and the somatic nervous system. The autonomic nervous system controls the organs and muscles in the body that work automatically, such as the heart and digestive system. The somatic nervous system controls the muscles in the body that we can consciously move, such as the muscles in our arms and legs.
Peripheral Nervous System Function
- The peripheral nervous system is responsible for relaying messages between the central nervous system and the rest of the body. It consists of the autonomic nervous system and the somatic nervous system.
- The autonomic nervous system controls the body’s involuntary functions, such as heart rate, digestion, and respiration. The somatic nervous system controls the body’s voluntary functions, such as movement and sensation.
Classification of Peripheral Nervous System
- The peripheral nervous system is responsible for transmitting information from the central nervous system to the rest of the body. It is divided into two parts: the autonomic nervous system and the somatic nervous system.
- The autonomic nervous system controls the involuntary activities of the body, such as heart rate, digestion, and respiration. The somatic nervous system controls the voluntary activities of the body, such as movement and sensation.
Role of the Peripheral Nervous System
The peripheral nervous system is responsible for relaying information between the central nervous system and the rest of the body. It consists of the spinal cord and a vast network of nerves that extend throughout the body. These nerves relay information about the environment, movement, and sensations such as pain, touch, and temperature. The peripheral nervous system also controls the muscles and organs in the body.
Disorder of the Peripheral Nervous System
- The peripheral nervous system (PNS) is the part of the nervous system that is outside of the brain and spinal cord. The PNS includes the nerves that run down the spinal cord to the rest of the body, and the nerves that run from the brain to the rest of the body.
- The PNS controls the muscles and glands in the rest of the body. It also collects information from the rest of the body and sends it to the brain. The PNS can be divided into the somatic nervous system and the autonomic nervous system.
- The somatic nervous system controls the voluntary muscles. The autonomic nervous system controls the involuntary muscles. The autonomic nervous system can be divided into the sympathetic nervous system and the parasympathetic nervous system.
- The sympathetic nervous system is the “fight or flight” system. It prepares the body for emergencies by increasing heart rate, breathing rate, and blood pressure. The parasympathetic nervous system is the “rest and digest” system. It slows down the heart rate, breathing rate, and blood pressure.
Treating Damage of Nerves
- Damage to the peripheral nerves can be caused by physical trauma, diseases, or exposure to toxins. When the nerve is damaged, the fibers that make up the nerve may be injured, severed, or crushed. This can disrupt the communication between the brain and the rest of the body, leading to problems with movement, sensation, or organ function.
- Nerve damage is often treated with surgery, physical therapy, and/or medication. Surgery may be necessary to repair the damaged nerve. Physical therapy may be recommended to help the patient regain movement and function. Medication may be prescribed to help reduce pain and improve nerve function.
FAQ’s on Peripheral Nervous System
What are the 3 parts of the peripheral nervous system?
The three parts of the peripheral nervous system (PNS) are sensory nerves, motor nerves, and the autonomic nervous system (ANS).
What is the peripheral nervous system and its functions?
The peripheral nervous system (PNS) connects the central nervous system (CNS) to the rest of the body. It controls communication between the CNS and body parts, allowing you to sense and move, among other functions.
What is the difference between CNS and PNS?
The central nervous system (CNS) includes the brain and spinal cord, controlling complex processes. The peripheral nervous system (PNS) extends throughout the body, managing communication between the CNS and other body parts.
What is the main function of CNS?
The central nervous system (CNS) processes and controls most body activities, including thinking, memory, and decision-making. It's like the command center of the body.
Which is more important CNS or PNS?
Both the central nervous system (CNS) and peripheral nervous system (PNS) are important. The CNS handles complex functions like thinking, while the PNS connects the body to the CNS, allowing it to sense and respond to the world. They work together.
