10/13 Abdomen II Flashcards
contents/traits of GI tract & co
unpaired organs: stomach, liver, spleen, pancreas
more ventral
singular a based on embryonic origin
contents/traits of UG tract & co
paired organs: kidneys, gonads, adrenal glands
more dorsal
R/L a supply
two layers of the peritoneum
parietal lines body wall
visceral lines organs
innervation of parietal peritoneum
GSA of spinal nn, well-localized pain
innervation of visceral peritoneum
GVA of autonomic nn, para and sym, referred/poorly localized pain
peritonealized/intraperitoneal
organs totally encompassed by the visceral peritoneum
retroperitoneal
organs posterior to peritoneum, only one surface or part is covered by peritoneum
space between peritoneal layers
peritoneal cavity or potential space
three types of mesentary
meso-: attached to dorsal wall
ligament: attached to two organs or to ventral wall
omentum: attached to stomach, multiple ligaments
components of lesser omentum
hepatogastric ligament (thin, transparent) hepatoduodenal ligament (vessels, portal triad)
components of greater omentum
gastrocolic ligament (ant/inf stomach-deep surface transverse colon) gastrosplenic ligament (stomach-spleen) gastrophrenic ligament (stomach-diaphragm)
retroperitoneal organs (“sad pucker”)
suprarenal glands (adrenals) aorta and IVC duodenum (2nd, 3rd, 4th parts) pancrease (most) ureters colon (asc/dec parts) kidneys esophagus rectum
two sacs of peritoneum
lesser sac (omental bursa) greater sac
omental bursa, formation/boundaries
formed during developmental rotation of foregut
ant: posterior stomach, gastrocolic ligament, lesser omentum
inf: transverse colon and transverse mesocolon
sup: caudate lobe of liver
omental bursa’s communication w/ greater sac
epiploic foramen of winslow
inf: 1st part duodenum
sup: caudate lobe of liver
post: IVC
ant: hepatic portal v in the hepatoduodenal ligament of the lesser omentum
