ANAT 3601 Lecture Notes - Lecture 2: Stratified Squamous Epithelium, Colic Flexures, Taenia Coli
● Mucus glands in the submucosa
○ Esophagus and duodenum
● Goblet cells in small and large intestine only! Not in stomach
● Greek translations
○ Instestine- enteron
○ Tongue- lingua
○ Liver- hepatos
○ Stomach- gaster
○ Kidney- nephros (renos)
○ Gall bladder- cystis
○ Omentum- apron
● Simple columnar epithelium lines the lumen of the stomach
● Simple cuboidal is located in the kidney, PCT and DCT and the thyroid follicles!!!!
● Simple squamous- good for exchanging gases so lines capillaries and blood vessels, respiratory membrane
between type I alveolar cell and capillary
● Stratified squamous- esophagus and anus
● Transitional epithelium- entire urinary system
● Match with characteristic:
○ Duodenum (first part of small intestine, has submucosal mucous): Brunner’s glands
○ jejunum/ileum- Peyer’s patches/ plicae circulares
○ Colon- teniae coli (means ribbons of colon)
○ Esophagus- stratified squamous epithelium
○ Stomach- rugae (folds) also present in bladder
● Match the cell type with its product
○ Gastric parietal cell- HCl
○ Paneth cell- lysozyme (gets rid of bacteria) also made in oral cavity
○ Enteroendocrine cell (found in stomach and small intestine)- gastrin (stomach), secretin to secrete
bicarboante and CCK (duodenum)
○ Neck cell in gastric pit- mucus in stomach
○ Chief cell- pepsinogen
● True regarding a lacteal
○ Named because early anatomists saw them filled with a “milky fluid”
○ Is part of the lymphatic system
○ Carries absorbed fats away from absorptive cells of small intestine
○ Found within the core of each villus
● Organ with the substance it produces
○ Small intestine: cholecystokinin, lysozyme, secretin
○ Stomach: HCl, pepsin, intrinsic factor, gastrin
○ Liver: bile
○ Pancreas: bicarbonate, lipases, proteases (makes bicarbonate to release to duodenum because
chyme has a pH of 2, need to neutralize) these are all exocrine
● Match organ with its mucus producing cells
○ Esophagus: submucosal glands
○ Stomach: mucous neck cells and mucus-secreting cells
○ Duodenum: Brunner’s glands (also submucosal)
○ Small intestine: goblet cells
● Associated with the large intestine:
○ Taenia coli
○ Splenic flexure

Document Summary
Goblet cells in small and large intestine only! Simple columnar epithelium lines the lumen of the stomach. Simple cuboidal is located in the kidney, pct and dct and the thyroid follicles!!! Simple squamous- good for exchanging gases so lines capillaries and blood vessels, respiratory membrane between type i alveolar cell and capillary. Match with characteristic: jejunum/ileum- peyer"s patches/ plicae circulares. Duodenum (first part of small intestine, has submucosal mucous): brunner"s glands. Colon- teniae coli (means ribbons of colon) Stomach- rugae (folds) also present in bladder. Match the cell type with its product. Paneth cell- lysozyme (gets rid of bacteria) also made in oral cavity. Enteroendocrine cell (found in stomach and small intestine)- gastrin (stomach), secretin to secrete bicarboante and cck (duodenum) Neck cell in gastric pit- mucus in stomach. Named because early anatomists saw them filled with a milky fluid . Carries absorbed fats away from absorptive cells of small intestine. Found within the core of each villus.
