Enteric Nervous System Flashcards
enteric nervous system characteristics
network of neurons buried in the lining of the gastrointestinal tract that controls the function of the digestive system
enteric nervous system operates
independently of the brain and spinal cord and communicates with the CNS through the parasympathetic and sympathetic nervous systems
enteric nervous system divided into
submucosal and myenteric plexuses
submucosal plexus charicteristics
embedded in connective tissue of the submucosa
submucosal plexus function
regulates local secretions, absorption, contraction of submucosal muscle and blood flow
myenteric plexus charecteristic
located between circular and longitudinal layers of the muscular externa
myenteric plexus function
*exerts control over motility of the GI tract
*increases the tone, as well as, intensity, and velocity of contractions
proteins in GI tract function
*fight infections
*make healthy cells
carbohydrates in GI tract function
provide source of energy
minerals in GI tract function
*keep bones strong
* helps transport oxygen in our blood
Ghrelin function
induces hunger
leptin function
causes sensation of satiety
arteries of transverse colon
medial colic and inferior mesenteric arteries
