What are the two systems 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.

What are the 2 peripheral nervous system?

The peripheral nervous system is divided into two main parts: 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 are the 2 types nervous system?

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 systems are in the PNS?

Parts of the PNS. The PNS can be divided into two components: the somatic nervous system and the autonomic nervous system. The somatic nervous system (SNS) and the autonomic nervous system (ANS) are both part of the peripheral nervous system. The SNS controls voluntary actions such as walking.

What is peripheral nervous system function?

The PNS has three basic functions: (1) conveying motor commands to all voluntary striated muscles in the body; (2) carrying sensory information about the external world and the body to the brain and spinal cord (except visual information: the optic nerves, which convey information from the retina to the brain, are in …

What are the 3 nervous systems?

It has three parts: The sympathetic nervous system. The parasympathetic nervous system. The enteric nervous system.

What is central nervous system and peripheral nervous system?

The central nervous system includes the brain and 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 are the 2 parts of the autonomic nervous system and what are their functions?

The two divisions of the autonomic nervous system are the sympathetic division and the parasympathetic division. The sympathetic system is associated with the fight-or-flight response, and parasympathetic activity is referred to by the epithet of rest and digest. Homeostasis is the balance between the two systems.

What are the two function of dendrites?

The functions of dendrites are to receive signals from other neurons, to process these signals, and to transfer the information to the soma of the neuron.

Is the enteric nervous system part of the central nervous system?

The enteric nervous system (ENS) is a large division of the peripheral nervous system (PNS) that can control gastrointestinal behaviour independently of central nervous system (CNS) input. Mammalian neurons are located in either the CNS (brain and spinal cord) or PNS (cells with soma outside the brain and spinal cord).

What are the four functions of the peripheral nervous system?

The 4 main functions of the nervous system are: Reception of general sensory information (touch, pressure, temperature, pain, vibration) Receiving and perceiving special sensations (taste, smell, vision, sounds) Integration of sensory information from different parts of the body and processing them.

What are the four main divisions of the peripheral nervous system?

The peripheral nervous system is subdivided into nerves, the autonomic system, and the somatic system. The autonomic nervous system is further subdivided into the parasympathetic and sympathetic nervous systems. The enteric nervous system is an independent subsystem of the peripheral nervous system.
