Abdominal Viscera Flashcards
where is the bare area of the liver located
bw coronary ligs
what grooves does the right parisagital groove of the liver have (2)
- Groove for vena cava
2. Groove for gall bladder
What attaches to the left parasagittal groove (2)
- attachment of lesser omentum
2. Attachment of round lig + falciform lig
What does the horizonatal lig of the liver surround
represents area of portal triad
what are the 4 lobes on the visceral surface of the liver
R, L, Quadrate and caudate
what are the 3 components of the portal triad
- hepatic a
- portal vein
- bile duct
will travel together and branch at the lobule
how is the billary tract formed
R+ L hepatic ducts form common hepatic duct and meet at bile duct with cystic duct from gallbladder
What does the bile duct meet with and where does that open
meets with pancreatic duct and empties thru hepatopancreatic ampulla which opens at 2nd portion of duodenum
what obstruction is jaundice indicative of
indicative of obstruction of bile duct
what is portal hypertension due to
increased pressure in portal vein due to liver cirrhosis
Where is the spleen located (rib lvl)
located at left side of supra colic compartment (@ 10th rib)
What are the 3 visceral surfaces of the spleen and how do they relate in space
Gastric anteriorly
colic inf
renal posteriorly
Where will a splenic rupture refer pain
blood will pool into peritoneal cavity- pain will refer to left shoulder in prone pos!
what are the 3 parts of the stomach
Fundus- above cardio opening, usually filled with air
Body- has greater and lesser curvature, ends at angular incisure
Pyloris- has 2 parts- pyloric antrum + Pyloric canal (has pyloric sphincter)
what are the mucosal folds in the stomach called
gastric folds/ rugea
What is a gastrojejuostomy and hiatal hernia
gastrojejunostomy- connection bw stomach and jejunum
Hiatal hernia- protrusion of parts of stomach thru diaphragm
what are the 4 parts of the duodenum and VB lvls
1st part- extends from pyloris and runs at level of L1 vert
2nd part- descend on r side of l1,2,3
3rd- crosses midline at lvl of l3
4th- ascends towards left side of l2- continuous with jejunum
what is the major and minor duodenal papilla
major- where bile and pancreatic duct exit
minor- where accessor pancreatic duct exits
What structure can be compressed in the head of the pacers when there is a cancer
Bile duct
What is meckel diverticulum
tube structure that mimics the appendix but comes from terminal illium
portions of the large intestine (6)
1st part- cecum- has ileocecal valve on medial surface. Has appendix as well. Reflates to r iliac fossa
Ascedning colon- goes as far and r colic flexure. Post is fused to post wall.
Transverse colon- travels as far as left colic flexure, longest portion, intraparituneal organ
Descding colon- ending at lvl of left iliac fossa, post surface is fused to postlat wall.
Sigmoid colon- curves towards midline and at level at s2/3 is continuous to rectum.
what are the 3 differentiating structures of the large intestine
Tania coli
Haustra- segmental look
oMental appendages
what are the 3 tania coli and location
Free tania coli on ascending and descending
omental tania on transverse
Tania mesincoli med/lat of ascending/descending and post of transverse
-all converge to appendix
what is mcburneys point
pain 3-4 cm away from asis towards the umbilicus (indicating apendix pain)
What is diverticolosis
multiple small external pockets of the mucosa extend thru muscular layer
folds inside small vs large intestine
small- circular folds
large- semilunar folds
what aa are the supra colic organs supplied by + branches (3)
Celiac trunk
- hepatic aa
- Left gastric aa
- splenic aa
What is the infra colic organs ( up to left colic flexure) supplied by + branches (3)
Sup mesenteric aa
- right colic aa
- middle colic aa
- iliocolic aa
What supplies the infra colic organs past the left colic flexure + branches
Inf mesenteric aa
- left colic aa
- sigmoid aa
- rectal aa
what 3 veins create the portal vein
Splenic vein
inf mesenteric vein
sup mesenteric vein
what vein from stomach drains directly into the portal vein
Right gastric vein
lesser and greater curvature of the stomach is supplied by what
lesser-Right and left gastric aa (r from common hepatic, l from celiac)
greater- R+ left gastroomental aa (l brach of splenic, r from common hepatic)
Gastic veins anastomose with these veins and what can it cause if there is portal hypertension
esophageal veins–> can cause esophageal vein blowuips
What supplies the head of the pancreas, duodenum
ant, sup and inf pancreaticoduodenal aa
what is the body and tail of the pancreas supplied by
splenic aa
Sympathetic and parasympathetic inn of supra colic organs
sympathetic- greater splanchnic (T6-9)
Parasympathetic- post vagal trunk
what are most infra colic organs supplied by: sympathetic and parasympathetic
most supplied by sup mesenteric ganglion
Sympathetic- leaser splanchnic T10-11
Parasympathetic- post vagal trunk
what also supplies a small portion of infra colic organs: sympathetic + parasytmpathetic
Inf mesenteric ganglion
symp- lumbar splanchnic (l1/2)
para- sacral plexus (S234)
