Gross Anatomy - Pertioneal Cavity And Neurovascular Supply To Abdomen

Front 1

largest serous membrane in human body

lies deep to endoabdominal fascia

Front 5

omentum

Back 5

stomach to other organs attachment

Front 6

peritoneal ligaments

Back 6

connect visceral peritoneum to small intestines/colon/stomach

Front 7

neurovascular supply of visceral peritoneum

Back 7

autonomic from underlying organs

Front 8

neurovascular supply of parietal peritoneum

Back 8

somatic innervation from somatic nerves that innervate adjacent abd wall of diaphragm

Front 9

greater and lesser sac

Back 9

subdivisions of peritoneal cavity, continuous with each other through omental foramen underside of liver

Front 10

subphrenic spaces

Back 10

deep to diaphram that absorb peritoneal fluid (lubricant). due to respiratory momvements?

Front 11

abd ostium

Back 11

uterine tube opening into peritoneal cavity. natural opening into a serous cavity! AH!

Front 12

dependent areas of peritoneal cavity

Back 12

supine: most dependent is hepatorenal access (R lobe and R kidney)

erect: pelvic portion of peritoneal cavity

Front 13

functions of peritoneum

Back 13

holds abd viscera in position

permits change in size, shape of viscera

FAT

conduit of passage of nuerovascular supply (like mesocolon extension)

Front 14

where does abd aorta terminate?

Back 14

L4, by dividing into L and R common iliac arteries

Front 15

where does abd aorta come from?

Back 15

descending thoracic aorta

Front 16

single midline branches of AA

Back 16

celiac trunk

superior mesenteric artery

inferior mesenteric artery

median sacral artery. at aortic bifurcation

Front 17

paired branches of AA

Back 17

inferior phrenic arteries: at aortic hiatus to supply diaphragm

middle adrenal arteries

renal arteries: to kidneys

lumbar arteries: 4 pairs into abd walls

ovarian and testicular arteries:

Front 18

L and R common iliac arteries

Back 18

from L4 to pelvic brim
divide into L and R external iliac arteries

L and R internal iliac arteries for pelvic brim and pelvic cavity

Front 19

inferior vena cavae

Back 19

originates at L5 from L and R common iliac veins

Front 20

common iliac veins

Back 20

along pelvic bring from external(lower limb)/internal iliac (pelvis) veins

Front 21

true or false: IVC ascends the posterior abd wall to teh LEFT of the abd aorta through the caval hiatus

Back 21

false

Front 22

venous return of paired branches of AA

Back 22

corresponding beins

Front 23

venous return of single midline branches of AA

Back 23

go through hepatic portal circulation --> hepatic vein --> IVC

Front 24

peripheral lymph nodes

Back 24

close to abd organ or w/o peritoneum. first set of lymph notes

Front 25

preaortic lymph nodes

Back 25

near origin of single midline arteries

named according to those arteries

aka celiac, superior mesenteric, inferior mesenteric

Front 26

lumbar lymph nodes/para aortic lymph nodes

Back 26

along AA and IVC.

from paired branches, abd wall muscles,

form common iliac lymph nodes

Front 27

common and external iliac lymph nodes

Back 27

located along blood vessels of same name

Front 28

cisterna chlyi

Back 28

sac like gathering of lymph vessels on posterior abd wall, near right of L1

gathers all from below diaphragm

Front 29

thoracic duct

Back 29

begins at cisterna chyli.

Front 30

sympathetic innervation to abdomen

Back 30

aortic plexus

lumbar sympathetic trunks

Front 31

aortic plexus

Back 31

from autonomic nerve fibers and preverterbral ganglia overlying AA. from aortic haitus to pelvic brim

Front 32

preganglionic sympathetic nerve fibers into aortix plexus

Back 32

throcic splanchnic nerve, lumbar splanchnic nerves

Front 33

postganglionic sympathetic nerve fibers into aortix plexus

Back 33

accompany blodo vessels and distribute via periarterial nerve plexus

Front 34

lumbar sympathetic trunk

Back 34

from symphatetic trunk in throax, and pelvis

4-5 ganglion per side

Front 35

lumbar sympathetic ganglia

Back 35

send postganglionic axons into somatic nerves of lumbar plexus

Front 36
