| Question | Answer |
|---|
| were is the abomasal impression on the liver? | bottom of left lobe (visceral surface) |
| where is the omasal impression on the liver? | upper left lobe (toward middle of liver) (visceral surface) |
| where is the duodenial impression on the liver? | on the right lobe (visceral surface) |
| where is the reticular impression on the liver? | on the caudate lobe |
| what makes the liver rotate? | growing rumen |
| species differences of caudate process of the caudate lobe? | ox= rectangular and projects beyond right border of liver. sheep= triangular and non projecting (once again...sheep and trifecta) |
| porcine liver can be described as....? | well LOBATED |
| porcine's liver's parietal and visceral surfaces contact what? | parietal = diaphragm. visceral = stomach |
| what animal's liver has no contact with the kidney? | pig |
| where is the renal impression on the liver? | caudate process of caudate lobe (CAUght the kidney) |
| lobation vs lobulation? | lobation = lobes and lobulation = lobules. Lobes > lobules. |
| path of the falciform ligament? | runs over diaphragmatic surface of liver, through notch for round ligament, to diaphragm to attach. |
| what forms the common bile duct? ( ductus choledochus?) | common hepatic duct + cystic duct (common hepatic--- hepatic wanted to start with C also) |
| what does the common bile duct open into? | major duodenal papillae |
| species differences in distance of major duodenal papillae from pyloris? | bovine= 50-70mm [sheep= 30-40mm (along with major pancreatic duct)] |
| sections of the pancreas? | left, body, right lobes |
| pancreas in ruminants? | small body, long right lobe, left lobe is broad (the righteous cow right path is long-- the wrong (left) is full of "broads") |
| pancreatic ducts in ox/pig? | accessory pancreatic duct (main duct) opens into MINOR duodenal papillae (ox and pig dont care if it's sweet--just eat it. therefore sweetness is just a minor accessory) |
| pancreatic ducts in sheep/goat? | major pancreatic duct opens into MAJOR duodenal papillae (pancreas is sweet-- MAJOR big deal in heaven and hell) |
| description of ox spleen? | flattened, spatulate/tongue shaped, visceral surface attaches closely to RUMEN (so phrenicosplenic and gastrosplenic ligaments are vestigial) [ox is all about the tongue...right down to the spleen) |
| spleen of sheep/goat? | flattened, rectangular/ triangular in shape (sheeps and goats, heaven and hell, trifecta and blood (spleen) ) |
| spleen of pig? | long and narrow, attached vertically to greater curvature of stomach **mostly in thoracic cage (only long and narrow part of a pig, haha) |
| what species have a red-brown spleen? blue-grey? | redbrown is bull/sheep and bluegrey is the cow. |
| Look at the kidney diagram picture | you know that shits coming back |
| what kind of kidney does a small ruminant have? | bean shaped, has a renal crest, no external lobulation |
| where is the location of the left kidney? the right? | left is L3-L5, right is T13-L3 |
| how would you describe the ox kidney externally? what does it lack? | lobated externally-- 18-20 lobes. NO RENAL CREST or RENAL PELVIS |
| which bovine kidney is unique, and how? | left is slightly twisted and displaced to the right by the rumen |
| describe the internal bovine kidney flow | lobes have pyramids, which have a renal papillae, which are drained by minor renal calices, which are drained my major calyces (CR and CA collecting ducts) which join to form the ureter |
| how is lobation indicated on the kidney of the pig/dog/sheep? | via the interlobar vessels internally, otherwise no external evidence |
| what animal has kidneys at the same level? where are they? | PIG! T13-L4 ...Rt kidney has no contact with liver (NO RENAL IMPRESSION) |
| drainage system of the kidney of the pig? | 10 minor calyces drain 10 medullary pyramids (which are fused at the base). 2 major calyces (cr and ca) drain to renal pelvis. |
| what are the cranial poles of the pig kidney associated with? | left and right lobes of pancreas, respectively. |
| the cr mesenteric artery CAN be aka? why? | usually arises from aorta independently, if arise from common trunk with celiac a, then called celiacomesenteric trunk |
| what does the cr mesenteric run along? | the jejunum, it branches into jejunal arterys, which anastomose. |
| what artery supplies the illeum, cecum, and ascending colon? | ileocolic |
| divisions on ca mesenteric artery? | left colic (descending colon), cranial rectal |

| Question | Answer |
|---|
| what does the ventral vagal trunk supply? | parietal surface of reticulum, omasum, and abomasum |
| where do the dorsal and ventral vagal trunks end? | both course over lesser curvature of abomasum and end at pylorus |
| what are the 4 lymphocenters of the abdomen? | lumbar, celiac, cranial mesenteric, caudal mesenteric |
| what is in the lumbar lymphocenter? | lumbar aortic ln |
| what is in the *celiac lymphocenter? | lienal/splenic lnn (craniodorsal border of spleen *routine meat inspection), hepatic lnn (at hepatic hilus. *meat inspection) |
| what is in the **cranial mesenteric lymphocenter? | jejunal lnn- routinely examined at meat inspections** |
| where are jejunal lnn in bovine? | prominant chain alongside mesenteric surface of jejunal coils (between last centrifugal coil of colon and jejunum) |
| where are the jejunal lnn in sheep? | chain of nodes between last centrifugal and first centripidal coils of colon |
| where are the jejunal lnn in pig? | middle of the mesentery (near root, by center of spiral colon) |
| where are the caudal mesenteric lnn? | run along branches of caudal mesenteric a within the mesocolon. meat inspection. |
