mesentery
Serosa - 10SubmucosaConnt. + BV
Submucosa gland (e.g. Brunner's) - 11Muscularis externaIn+out circ/long. layers of muscularis externa
peristalsis + segmentation - 12MucosaMuscularis mucosa
Lamina propria
mucosal gland
epithelium - 13What controls muscularis mucosa?Meissner's complex
- 14What controls muscularis externa?Myentric plexus
- 15OesophagusVariable muscle types in M.externa
SSNon-KE
Mucosal+submucosal folds. - 16Function of epitheliaProtection, poor absorption
- 17Variable muscle type meansSome voluntary, some involuntary
- 18Stomach muscle layersLong+circ. as well as an additional oblique layer.
- 19Stomach epithelia functionHostile enviro.
Can't use multilayer ep. tho because absorption takes place here
Forms a secretory sheet - 20Secretory Sheetevery cell secretes mucus
