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 two major divisions of the peripheral nervous system?

The peripheral nervous system is further subdivided into an afferent (sensory) division and an efferent (motor) division. The afferent or sensory division transmits impulses from peripheral organs to the CNS.

What are the two main divisions of the peripheral nervous system how do these systems relate to the three types of muscle?

The two main divisions are the Somatic Nervous System and Autonomic Nervous System. The Somatic Nervous System controls the skeletal muscle system as well as the external sensory. The autonomic nervous system controls involuntary muscle systems such as smooth muscle and cardiac muscle.

What is the function of the peripheral nervous system quizlet?

What are the functions of the nervous system’s main divisions quizlet?

The two main PNS divisions are the somatic nervous system (which enables voluntary control of the skeletal muscles) and the autonomic nervous system (which controls involuntary muscles and glands by means of its sympathetic and parasympathetic divisions). Neurons cluster into working networks.

What is the sympathetic division of the autonomic nervous system?

The sympathetic division of the autonomic nervous system regulates the flight-or-fight responses. This division also performs such tasks as relaxing the bladder, speeding up heart rate, and dilating eye pupils.
