GI Nervous Control


  • Nervous Control of GI System
    • Enteric nervous system coordinates 
      • Autonomic network of neurons around GI tract independent of (but in communication with) parasympathetic/sympathetic nervous system
      • Coordination of peristalsis (motility), segmentation (churning/mixing), and secretion (of enzymes and hormones) after eating
    • Stimulated by parasympathetic activity (rest and digest)
    • Inhibited by sympathetic activity (fight or flight)
