Autonomic Innervation: Summary

00:01 So that is the autonomic nerves of the abdominal pelvic region.

00:05 Let's just summarize by having a look at the various different effects the sympathetic and parasympathetic will have.

00:12 So the sympathetic nervous system will inhibit peristalsis constrict blood vessels within the abdomen and contract internal anal sphincter for example.

00:22 The parasympathetic is going to stimulate peristalsis.

00:25 It will promote the secretion of digestive juices and help to relax internal anal sphincter, for example.

00:33 If we were to have a look at the liver and the gallbladder, the sympathetic effect will be to stimulate the breakdown of glycogen to glucose.

00:40 Whereas, parasympathetics will stimulate the conversion of glucose to glycogen increases secretion of bile.

00:48 If we were to look at the impact on the pancreas, it would inhibit insulin secretion with sympathetic in control.

00:55 Whereas, parasympathetic will stimulate insulin secretion.

00:59 And if we look at the suprarenal glands, the sympathetic effect will be to promote the sympathetic release of adrenaline.

01:07 If we look at the kidneys as part of the urinary system, sympathetic is going to slow you in production by vasoconstriction.

01:14 And it will contract the internal urethral sphincter.

01:17 Parasympathetic is going to contract the detrusor muscle of the bladder and inhibit contraction of the internal urethral sphincter allowing you into pass out of the bladder.

01:27 For the genital system, the sympathetic is going to induce ejaculation and remission of engagement due to vasoconstriction.

01:34 And that is where the parasympathetic is going to produce engorgement of that erectile tissue.

01:41 So there's a lot to do with the autonomic nervous system, and the various complexity that we have within the abdomen and the pelvic region.

01:49 The final aspect we're going to talk about is referred pain.
