GI INNERVATION Learning Exercise

In class I briefly told you that the parasympathetic nervous system increases GI activity, and the sympathetic nervous system decreases it. Now I want YOU to take this information further and figure out for yourself the following: How SPECIFICALLY will the parasympathetic and sympathetic divisions affect the following functions?

 

GI Action Parasympathetic division will: Sympathetic division will:
Salivary glands (will secretion be increased or decreased?)    
Peristalsis (increased or decreased?)    
Gastric Glands (increase or decrease secretions?)    
Bile Production (increased or decreased?)    
Pancreatic juice secretion (increased or decreased?)    
Sphincters (will it open or close the GI sphincters?)    
Overall blood flow to GI tract (which ANS division will send MORE blood to the GI tract? which will send less or inhibit excess blood flow to GI tract?)
