Glands and Tonsils on the Models
• Submandibular gland
• Sublingual gland
• Parotid gland
• Palatine tonsil
• Pharyngeal tonsil
PANCREAS AND SPLEEN MODELS
• Kidney• Gall bladder• Pancreas• spleen (function is to remove foreign antigens
and aging RBC’s) • duodenum• plicae circularis
GI MODEL• Stomach• Pancreas• Spleen• Pyloric sphincter • circular folds (known as plicae circularis; these are macroscopic folds in the
mucosa)• ascending colon• transverse colon• descending colon• tenia coli• Jejunum (middle part of small intestine)• Ileum• Cecum• Ileocecal valve• Appendix• Rectum• NOTE: Plicae circularis, microvilli, and villi all increase the surface area of
the small intestinal lining
INTESTINE MODEL• Stomach• Pancreas• Spleen• Pyloric sphincter • circular folds (known as plicae circularis; these are macroscopic folds in the
mucosa)• ascending colon• transverse colon• descending colon• tenia coli• Jejunum (middle part of small intestine)• Ileum• Cecum• Ileocecal valve• Appendix• Rectum• NOTE: Plicae circularis, microvilli, and villi all increase the surface area of
the small intestinal lining
Tenia coli
Mesentery
Pancreas
Common bile duct
Duodenum
Appendix
CecumSigmoid colon (first half)
Ascending colon
Descending colon
SLIDES
• Small intestine – Villi, microvilli, and plicae circularis: (Serve to
increase the surface area of the small intestine)
– Intestinal crypts
SLIDES
• Spleen: removes foreign antigens and aging RBC's– Red pulp– White pulp
• Pancreas– Islets– Acini
– Be able to tell the difference between liver, spleen, pancreas, and kidney slides!
