    Transcript
    In this lecture I am going to talk about the autonomic nerves of the abdominopelvic organs. Now this area of anatomy, the autonomic nervous system, and specifically the autonomic nervous supply to the gastrointestinal organs. can be a little bit complicated. And many students that I teach often struggle with understanding this. So we are going to have a look at some important definitions first. Have a look at the overview of the autonomic nerves of the abdominopelvic organs; because that's really important to understand the basic principles before we go onto supply the specific nerves of the stomach, small intestine, large intestine the rectum, anal canal and the reproductive organs. Towards the end we will then indicate why good understanding of the autonomic nervous system is important for the function of the body, maintaining the internal environment and also for a phenomena called referred pain. And we mentioned that at the very beginning when we talked about to with regard to appendicitis and we will come back to it. And hopefully this time we will make more sense now we've understood the nerve supply, both somatic and autonomic. So the autonomic nervous system controls the activity of the internal viscera. So we are not able to alter this in any way We can't stand or sit and actively increase the rate of peristalsis. We can actively move our body, we can make biceps contract, we can stand up, we can walk. But we can't alter the amount of pancreatic juice that the pancreas releases. The amount of bile that liver produces. This is all done via our autonomic nervous system and its done without our conscious; without unconsciously being aware. So generally with regard to the abdominopelvic organs the sympathetic division of the autonomic nervous system decreases its general...

    Great lecture!
    By Hugo M. on 14. February 2017 for Autonomic nerves of the abdominopelvic organs

    I have been struggling to understand how the ANS works in the abdomen and pelvis but after this lecture things are starting to make a lot more sense. Thank you so much! Great job!
