Enteric nervous system connectivity secretory cells chemo rc mechano rc osmo rc. Secretions: salivary glands, stomach, pancreas, liver, small intestine, salivary glands - parotid, submandibular (submaxillary) and sublingual secrete, saliva, serous cells (parotid) - (cid:68)-amylase. Lipase: mucous cells (submaxillary and sublingual) - mucin. 6: gastric secretions (stomach, columnar epithelial cells and mucous cells. Intrinsic factor: cheif cells - pepsinogen, g cells - gastrin, d cells - somatostatin, enterochromaffin-like cells - histamine, gastrointestinal tract. 3na+ somatostatin rc prostaglandin rc histamine rc gastrin/cckb rc muscarinic cholinergic rc lumen.
