what fiber types are in splancnic nerves?

GVE primarily, also GVA; not GSE or GSA because not skeletal muscle

31

what is right coronary artery dominance?

dominance is which coronary artery gives rise to posterior interventricular artery

32

what is an "end" artery?

no anastomosis

33

why are coronary arteries "functional" end arteries?

do have some anastomoses but not enough to do collateral circulation

34

when do coronary arteries fill with blood?

diastole because valves are away from sinuses of aortic semilunar valves

35

usual area of "referred pain" from the heart?

left arm, left jaw; T1-5, C2-3

what comprises conduction system of the heart?

cell depolarization; SA node; AV node by inter antrial septum by bundle of His; perkinje fibers

37

what and where is fossa ovalis? what was it embryologically?

between R and L atria; it is oval shape; was foramen ovale which shunted blood from R atrium to L atrium without going through pulmonary system

38

which valves work via pressure differences, which via muscular actions?

pressure: aortic, pulmonary (semilunar)

muscular: tricuspid, mitral (atrio-ventricular)

39

what makes A-V flaps move?

cordae tendinae with papillary muscles

40

where is moderator band?

RV

41

role of greater omentum?

provides fatty apron over abdominal viscera, organs; contains infections in viscera from spreading; promotes healing, supports/protects from ulcers

42

structures of portal triad

bile duct, hepatic artery proper, portal vein

43

intraperitoneal

develops within mesentery

44

primarily retroperitoneal

developed behind mesentery, stayed there

45

secondarily retroperitoneal

developed within mesentery but migrated out - adheres to posterior peritoneal wall

46

extraperitoneal

developed outside of mesentery (bladder)

47

primarily retroperitoneal mnemonic

kids and infants are tiny

kidney, aorta, ivc, adrenal glands, testes

48

secondarily retroperitoneal mnemonic

AC/DC rockers can party down

ascending colon, descending colon, rectum, cecum, pancreas, duodenal root

49

extraperitoneal mnemonic

BEE soup

bladder, seminal vesicles, ovary, uterus, prostate

50

alimentary tract, proximal to distal

mouth, esophagus, cardiac sphincter, stomach, pyloric sphincter, duodenum (4 parts), jejunum, ileum, cecum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, anus

51

subdivisions of the "small" intestine?

duodenum, jejunum, ileum

52

parts of small intestine that are intra/retroperitoneal?

75

why important that IVC is dorsal to portal vein?

if have portal hypertension, and hemorrhaging blood in esophagus, can hook up portal vein to IVC and alleviate esophageal problem but then get toxins in blood because liver isn't filtering anything

short circuit portal system, take it out of hepatic system

76

main tributaries of portal vein?

superior mesenteric vein > splenic vein

inferior mesenteric vein > splenic vein, although sometimes > superior mesenteric vein

77

portal vs hepatic vein?

portal: takes blood from GI tract > liver for filtration

hepatic: takes blood from liver that is detoxified > IVC > heart

left vs right renal vein

left is larger than right
