assess the similarities and differences between the somatic nervous system and the autonomic nervous system
Effectus [21]

Similarities and differences are explained below

Explanation:

Differences:

somatic nervous system:

  • It is part of the peripheral nervous system associated with the voluntary control of body movements through the skeletal muscles and mediation of involuntary reflex arcs.
  • It has sensory and motor pathways.
  • It controls muscles and movement.
  • System responses are based on skeletal muscle contraction.

Autonomic nervous system:

  • The autonomic nervous system is subdivided into the sympathetic nervous system and  parasympathetic nervous system
  • It possesses only motor pathways.
  • It controls glands and internal organs.
  • This system works automatically, without a person's conscious effort.

Similarities between  the somatic nervous system and the autonomic nervous system:

Both have  motor pathways

Both the system use nerve impulse

Both the system Weaken Myocytes

Both the system use glucose as an energy source for the muscles that they control

Both the system are controlled by the CNS

Both possess neurons
