What is the difference between sensory and motor divisions?
The afferent or sensory division transmits impulses from peripheral organs to the CNS. The efferent or motor division transmits impulses from the CNS out to the peripheral organs to cause an effect or action.
What is the difference between the two divisions of the motor nerves in the peripheral nervous system?
Subdivisions of the peripheral nervous system
The visceral sensory division carries signals mainly from the viscera of the thoracic and abdominal cavities. The motor (efferent) division carries motor signals by way of efferent nerve fibers from the CNS to effectors (mainly glands and muscles).
What are the two main divisions of the nervous system called?
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 are the two main divisions of the peripheral nervous system what are their functions?
Like the nervous system as a whole, the peripheral nervous system also has two divisions: the sensory division and the motor division. The sensory division of the PNS carries sensory information from the body to the central nervous system.
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.
What is the main function of the peripheral nervous system?
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 is an example of the peripheral nervous system?
The peripheral nervous system includes the cranial nerves, the spinal nerves, the sympathetic nervous system, and the parasympathetic nervous system.
