Regulation of Gut Function and Motility Flashcards
Where do the sympathetic preganglionic neurons arise from
Where do the postganglionic neurons arise from
Where does the parasympathetic nervous system arise from
What is the enteric nervous system
Intrinsic
Autnomous
Also interact with sympathetic and parasympathetic
Where are the meissner and auerbach plexus located
What does the myentric plexus do
What does the submucosal plexus do
What is the local reflex of the enteric nervous system
What does the extrinsic nervous system do on intrisic
What is hirschsprung disease
Common cause of neonatal bowel obstruction
Tonal contraction without relaxation
Intestinal distension proximal to rectum
Most require surgery
Congenital absence of ganglion of myenteric and submucosal
What are examples of endocrine gut hormones
What are examples of paracrine gut hormones
What are example of neurocrine cells
What are enteroendocrine cells
Possess hormone containg granules concetrated at basolateral membrane
Secretion in response to stimuli: small peptides, amino acids, fatty aicds, oral glucose, distension of an organ and vagal stimulation
