In the cat, identify the following organs and features. The page numbers refer to Gilbert's Pictorial Anatomy of the Cat.

Make three illustrations:
    1)  Head, esophagus and stomach (dissected open to show rugae)
    2)  Liver and its features
    3)  Stomach through the rectum
 

I. HEAD THROUGH STOMACH
 

	salivary glands: (pp 20-21, 38)     parotid & duct around and below the ear     submaxillary below parotid, under posterior facial vein
	esophagus in cervical, thoracic and diaphragm region
	stomach (pp. 43-45, 49)     lesser and greater curvatures     fundus uppermost rounded portion     lesser omentum connects to liver     left gastric artery branches fr celiac art.     greater omentum hangs below     cardiac orifice entry into stomach     pyloric sphincter exit from stomach Here is a labeled image of the stomach.
	cut along the greater curvature to open stomach and see:     rugae inside stomach     contents What did it last eat?     Any parasites?

II. LIVER
 

	liver : (pp. 42-46)     coronary ligament superior edge     gall bladder shriveled between lobes     common bile duct lies behind duodenum (Note that the duodenum is green where the bile duct empties into it. )
	liver : (pp. 42-46)     falciform ligament anterior edge     round ligament anterior edge of falc. lig     coronary ligament superior edge Here is a labeled image of the liver and its ligaments.

III. STOMACH THROUGH RECTUM
 

	stomach (outline)     pyloric sphincter duodenum first few cm after stomach pancreas (p. 50) lies in curve of duodenum     pancreatic duct joins bile duct at duodenum
	cut open the duodenum to see the villi
	mesenteries : (p. 49)     superior mesenteric artery     lymphatic vessels (yellow)     cisterna chyli (large & yellow)
	ileum  (terminal part of sm intestine)     lymph nodes     ileocecal valve cecum (p. 49)  (blind proximal end of colon below ileocecal valve) Here is a labeled image of the junction of the ileum and the colon.

jejunum (after duodenum)
make a 2" longitudinal cut, note:
    villi like velvet
    (see any parasites? probably Ascaris)

ascending colon (indistinct in cat)

transverse colon (indistinct in cat)

descending colon (indistinct in cat)

sigmoid colon (indistinct in cat)

rectum  (straight terminal portion of colon)
