Pig and Camelid Abdomen Flashcards
What unique feature does the pig stomach have?
Diverticulum ventriculi (gastric diverticulum) in fundic region
separated from rest of stomach by a spiral groove
Diverticulum ventriculi (gastric diverticulum)
Describe the pig stomach interior
non-glandular part close to esophageal opening
rest is glandular
What is unique about pyloric sphincter in pigs
It is incomplete
Has a well developed torus pyloricus
What is unique about the pig liver
NO contact with right kidney
so no renal impression
no papillary process
Quadrate lobe does not reach ventral border
1) left lateral lobe
2) quadrate hepatic lobe
3) left medial lobe
4) falciform lig and round lig
5) gall bladder
6) right medial lobe
7) right lateral lobe
8) cystic duct
9) bile duct
10) portal vein
11) hepatic artery and portal lymph nodes
12) caudate process
13) caudal vena cava (runs in caudate process)
Where does caudal vena cava run in the pig
in caudate process of liver
What does the pig liver look like? Clin sig
Distinct leathery appearance
Has well-developed fibrous tissue that makes aspiration impossible
- Left lateral lobe
- Left medial lobe
- Quadrate lobe
- Right medial lobe
- Right lateral lobe
- Caudate proc. of the caudate lobe
- Porta hepatis
- Gall bladder
True or false: Pigs have a sigmoid loop in cranial duodenum
True
What opens into the major duodenal papilla in pigs? the minor?
major: bile duct
minor: accessory pancreatic duct
Where in the pig’s body is the jejunum
mostly Right of the midline, (displaced to the
right by the coils of the ascending colon).
Discuss ileum opening into the large intestine
Opens by a prominent ileal papilla at the ileoceco-colic junction
Also frenulum (fold of mucosa) extend on either side of the ileal papilla for support
Where is the cecum located in pigs
mid -left flank
apex points caudoventrally on the left side.
How many taeniae are in pig cecum
3 longitudinal (right left and central)
forms three rows of sacculations (haustra)
Describe where the colon lives in the pig abdomen
ileoceco-colic junction lies ventral to left kidney
colon lies in the left, caudal to stomach
Describe the pig ascending colon
cone shaped (apex is ventral)
Ansa spiralis: cone shaped reaches to floor of abdomen dorsal to the umbilicus
- 3 centripetal sacculated (2 teniae) > central flexture >
3 centrifugal gyri (inside, narrower, smooth) no teniae
No proximal loop - No distal loops - No sigmoid colon
Describe location of the pig kidneys in the abdomen
right and left are symmetrically placed
right does not contact liver
Describe pig kidney external appearance
flattened, smooth (fused cortex)
