What is the peripheral nervous system?
Q: What is the peripheral nervous system?
A: The peripheral nervous system, or PNS, consists of the nerves and ganglia which are outside the central nervous system (the brain and spinal cord).
Q: What is the main function of the PNS?
A: The main function of the PNS is to connect the central nervous system (CNS) to the limbs and organs.
Q: How is the PNS different from the CNS?
A: The PNS is not protected by bone like the central nervous system, and it is exposed to toxins and mechanical injuries.
Q: How is the PNS divided?
A: The peripheral nervous system is divided into the somatic nervous system (SNS) and the autonomic nervous system (ANS).
Q: Is the enteric nervous system (ENS) part of the autonomic nervous system?
A: No, the enteric nervous system (ENS) can be seen as a third branch of its own and not as part of the autonomic nervous system.
Q: What is the somatic nervous system responsible for?
A: The somatic nervous system (SNS) is responsible for voluntary movements and sensory information.
Q: What is the autonomic nervous system responsible for?
A: The autonomic nervous system (ANS) is responsible for regulating involuntary body functions, such as heart rate and digestion.
