A&P Discussion

Parasympathetic and sympathetic activation are two competing effectors of the autonomic nervous system. Many organs have dual innervation, allowing changes in a split second through chemical messengers. Your task is to discuss how the autonomic nervous system responds to changes in homeostasis and provide a comparison between autonomic and somatic nerves.

You should spend approximately 4 hours on this assignment.


  1. You are making your way to your car when suddenly your overly friendly neighbor pops out from behind a bush and yells “Surprise!” Focusing on one organ with dual innervation, prepare a written post with at least 300 words answering the following bullet points:
    1. What physiological events are happening in your chosen organ as you are going about your normal morning routine?
    2. How does being frightened by your neighbor alter the biological processes in your chosen organ? Be sure to include chemical messengers involved in inducing this change in physiological state.
    3. How do the two branches of the autonomic nervous system maintain homeostasis in your chosen organ?
    4. Provide a brief comparison between autonomic and somatic peripheral nerve action.
  2. All references must be cited using APA Style format. Please refer to the CCCOnline APA Citation Toolkit.
