? | | Jejunum paneth cells are bright red in crypts mucosa and submucosa sept by muscularis mucosae lamina propria full of lymphocytes |
? | | neutrophils are infiltrating the mucosa and submucosa of gallbladder acute cholecystitis w/right upper quad abdominal pain & tenderness on palpation. |
? | | Duodenum - can tell because of brunners glands |
? | | transition between duodenum and pyloris pits turn into villi mucus glands(stomach) into submucosal glands |
? | | Esophageal stomach junction stomach simp columnar esophagus - non-keratinized stratified squamous lymphoctes in lamina propria |
? | | Esophagus - distinct layers epithielium - non kerat startified squamous lamina propria - less lymphocyte muscarlis mucosa thicker |
? | | |
? | | |
? | | |
? | | Esophagus with submucosal gland |
? | | Barretts columnar epithelium on left and squamous epithelium on right. intestinal metaplasia (note the goblet cells in the columnar mucosa). |
? | | Esophagus - note the lymph node and the lymphocytes migrating |
? | | Esophagus - note the connective tissue papillae |
? | | Esophagus with transition between skeletal and smooth Smooth - many nuclei Skeletal - Nuclei out to periphery |
? | | Esophagus - muscularis externa |
? | | parasympathetic ganglion on tongue |
? | | |
? | | |
? | | Tongue - keratinized tips form when cells accumulate keratinohyalin and it hardens into keratin |
? | | Tongue - papillie with taste buds |
? | | Tongue with taste buds outlined in white |
? | | |
? | | Small intestine with dividing cells in the crypt |
? | | Transition from stomach to small intestine - note how the mucusal glands in stomach give way to the submucosal glands in the intestines |
? | | Colon - mucosa of the colon is distinct because you have straight crypts with no villi |
? | | |
? | | Colon - crypts with no villi, mucus in goblet cells is stained red |
? | | |
? | | Colon - the cut gives a flower patch appearance |
? | | Appendix - crypts with no villi have a lot of lymph tissue and some well organized lymph nodes |
? | | Colon - white arrows point to absorptive cells in the crypts which outnumber goblet cells |
? | | Appendix - notice the lymph nodes |
? | | Intestine muscularis externa |
? | | Jejunum - crypts outlined in green you have paneth cells (excrete lysozymes) goblet cells - mucus |
What portion? | | Small Intestine - duodenum because you have submucosal glands serosa covered with mesothelium |
? | | Intestine - notice Auerbachs plexus |
? | | |
? | | Small Intestine - note that the epithelial cells are continuous with the crypts |
? | | |
? | | Stomach a - chief cells b - parietal cells c - gastric pits surface mucus cells |
? | | Stomach with gastric glands |
? | | stomach with gastric glands |
? | | |
?? | | |
? | | |
? | | Gastric pits with closely packed tubular glands |
? | | Gastric mucosa surface mucous cells |
? | | Gastric mucosa chief cells and parietal cells |
? | | |
? | | gastric mucosa surface mucus cells |
? | | |
? | | Ileum - look at the lymph nodes that protrude out into the lumen and extend into the submucosa |
