Introduction: The ANS is the part of the nervous system

Introduction: The ANS is the part of the nervous system that  supplies the internal organs and structures, including the blood  vessels, stomach, intestine, liver, kidneys, bladder, genitals, lungs,  pupils, heart, and sweat, salivary, and digestive glands. Two divisions  of ANS (the sympathetic and parasympathetic) have opposite functions. As  we learned, the sympathetic nervous system prepares the body for  intense physical activity and is often referred to as the  fight-or-flight response. The parasympathetic nervous system has almost  the exact opposite effect, relaxes the body, and is often referred to as  the rest-and-digest response.

For this post, you have to write at least 400 words addressing the  following 5 points. Please identify each point in your answer.

  1. Choose an organ in the body that has autonomic innervation. (LUNGS)
  2. Next, describe how the organ you have chosen is affected by one of  the two divisions of the ANS. Is it stimulated? Inhibited? Which part of  the organ is affected? Do not do both divisions of the ANS.
  3. Identify the location and neurotransmitters of the preganglionic and  postganglionic neurons that innervate the organ you chose from the  division (sympathetic or parasympathetic) you chose.
  4. Would your organ be controlled through a gray ramus communicans, splanchnic nerve, cranial nerve, or sacral spinal nerve?
  5. Describe a situation, like a car crash, that increases or decreases  the activity of your organ, and explain the effect that situation would  have on your organ. Compare that effect to normal basal levels of your  organ’s activity. Explain how the change(s) in the activity of the organ  of your choice might be perceived, if at all. Other situations could  include a job interview, relaxing on a beach, encountering a growling  dog while walking outside, jumping out of the way of an oncoming  vehicle, getting a massage, feeling unsafe while walking down a dark  street at night.

This is a first come first serve choice, so please review the  previous postings to choose your organ. If one student chooses an organ  like the eye, then only the regulation by either the sympathetic or  parasympathetic nervous system should be discussed. One organ per  student. Duplications are not allowed, and such postings will be deleted  by the instructor. If you cite a specific source, please include the  reference (APA format).
