Lab Questions Table Conf 2 Cont'd Flashcards
early pain from appendicitis?
referred to T10, belly button
3 unpaired vessels of abdominal aorta?
celiac, SMA, IMA, median sacral
vertebral level of celiac trunk?
T12
vertebral level of SMA?
LI
vertebral level of IMA?
LIII
what do ventral branches of aorta tend to do?
supply gut, unpaired organs like liver
what do lateral branches of aorta tend to do?
supply specific paired organs, like kidneys
direct branches of abdominal aorta?
renals, medial suprarenals, inferior phrenics, testicular/ovarian, lumbars (1-4)
arteries that supply diaphragm?
superior and inferior phrenics, musculophrenic, pericardiacophrenic
inferior phrenics arise from?
abdominal aorta
superior phrenics arise from?
thoracic aorta
musculophrenic and pericardiacophrenic arise from?
internal thoracic artery
suprarenal glands supplied by?
superior, medial, inferior suprarenal arteries
hepatic v. portal vein?
portal: carries blood from all digestive organs into liver for filteringhepatic: carry blood away from liver into IVC for systemic circulation
what is “marginal” artery? where? clinical significance?
inside the Mesentery; connects vessels carrying blood to vasa recta; suppled by both SMA and IMA, so major collateral route
left renal vein function?
drains much of left part of abdomen, direct extension of IVC
why called “bare area” of liver?
no peritoneum, liver directly contacts diaphragm
what are coronary ligaments?
on “crown” of liver, connect to diaphragm
bile passage route?
bile made in liver > hepatic duct > common bile duct when joins cystic duct > duodenum or back through cystic duct to gall bladder for storage
IVC location re: portal vein?
dorsal
main tributaries of portal vein?
SMV, splenic vein
wehre woudl you feel biliary colic?
T7-9
hepato-portal system function
drains blood from digestive organs into liver for filtration before entering systemic circulation
superior mesenteric artery branches
inferior pancreaticoduodenal artery, intestinal arteries, ileocolic artery, right colic artery, middle colic artery
intestinal arteries supply?
jejunum, ileum
ileocolic artery supplies?
cecum
appendicular artery is branch of?
ileocolic artery, anastomoses also wit right colic artery
right colic artery supplies?
ascending colon
middle colic artery supplies?
transverse colon
superior mesenteric vein + splenic vein =
hepatic portal vein
what holds on to duodenum?
suspensory ligament of the duodenum, from right crus of diaphragm to duodenojejunal junction
where do ileum and cecum meet?
ileocecal junction
IMA is in what peritoneal plane?
retroperitoneal
IMA branches
left colic a., sigmoid a., superior rectal a.
left colic artery supplies
descending colon and left third of transverse colon
sigmoid arteries supply
sigmoid colon
superior rectal artery supplies
proximal part of rectum
inferior mesenteric vein branches correspond with
IMA branches
parts of large intestine
cecum (attaches appendix), colon (ascending, tv, descending, sigmoid), rectum, anal canal
appendix suspended in
mesoappendix
what is within mesoappendix
appendicular artery
sigmoid colon’s mesentery
sigmoid mesocolon
3 features that distinguish large from small intestine
teniae coli, haustra, omental appedices/epiploic appendages
4 parts of duodenum
superior/1st (L1), descending/2nd (L2), horizontal/3rd (L3), ascending/4th (L2
ampulla of duodenum
duodenal cap/duodenal bulb
parts of pancreas
head, neck, body, tail
uncinate process
small projection from inferior margin of pancreas, posterior to mesenteric vessels
blood supply to pancreas
posterior and inferior pancreaticoduodenal arteries, dorsal pancreatic artery, greater pancreatic artery, left gastro-omental artery
portal-caval anastomoses
gastroesophageal, anorectal, paraumbilical, retroperitoneal
portal hypertension
hepatic portal system’s veins have no valves; when they become blocked, get portal hypertension, tributaries engorge, get hemmorhoids and varicose gastric/esophageal veins
internal features of stomach
gastric folds, pyloric antrum, canal, sphincter, orifice, ampulla of duodenum
major duodenal papilla
opening of main pancreatic duct and bile duct
minor duodenal papilla
draining of accessory pancreatic duct
what kinds of folds between haustra?
semilunar
clinical conditions caused by compromised portal circulation
esophageal varices, caput madusae, internal hemmorhoids
