1- foregut : osephageas - stomach - middle of 2 nd part of duodenum- liver - spleen- pancreas
Supplies by cliac trunk
2-midgut : middle of 2 nd part of duodenum till rt 2/3 of transverse colon
Supplied by sma
3- hindgut : lt 1/3 of transverse colon till the upper half of anal canal
Supplied by ima
Coeliac trunk
(4)
( level- relations - branches - nickname)
1- at the level of upper border of L1
2- behind the posterior wall of lesser sac related to celiac plexus of nerves , celiac lymph nodes, celiac ganglia and crura of diaphragm
3- branches :
Left gastric
Common hepatic
Splenic
4- artery of foregut
Talk about left gastric a
- run along the lesser curvature to anastomosis with the right one
- gives osephageal branches that letter anastomosis with the osephageal branches from thoracic aorta
Talk about the splenic a
(5)
1- the largest branch of celiac trunk
2- behind the posterior wall of lesser sac
3- runs on the upper border of body of pancreas
4- passes through the lienorenal ligament to reach the spleen
5- branches :
- left gastroepiploic
- short gastric
- pancreatic
- terminal splenic
Talk about common hepatic a
1- gives right gastric a
2- gastroduodanul a ~> superior pancreaticoduodenal , right gastroepiploic
Then changes its name to proper hepatic
Then gives - supraduodenal
- rt , lt hepatic
- cystic
Talk about sma
(Level - nickname - branches) (3)
1- the artery ofmidgut
2- at the level of lower border of L1
3- branches
- inferior pancreaticoduodenal
- jejunal
- ileal
- ileocolic
- right colic
- middle colic
Talk about inferior pancreaticoduodenal , jejunal, ileual , middle colic
1- inferior pancreaticoduodenal
(5)
1- the first artery
2- sma gives it before entering the root of mesentry
3- runs between head of pancreas and duodenum
4- supplies the inferior half of head and duodenum
5- anastomosis with the superior
Ileul
8:10 branches
In the root of mesentry
Supplies ileum
Jejunal
8:10 branches
In the root of mesentry
Supplies jejunum
Middle colic
Enters the mesocolon
Gives rt, lt branches
Talk about right colic , ileocolic
1- right colic
- gives ascending , descending
- supplies ascending colon, right flexure
2- ileocolic
- gives superior, inferior
- superior supplies ascending colon
- inferior gives 5 branches
• anterior cecal
• posterior cecal
• ileul : supplies the terminal ileum and then ANASTOMOSIS WITH THE SMA
• appendicular
• colic : supplies the ascending also
Talk about ima (3)
( level - nickname- branches )
1- artery of hindgut
2- at the level of L3 ( behind the 3rd part of duodenum )
3- branches :
- left colic
- sigmoid
- ends as superior rectal
Talk about portal vein (3)
1- formed behind the neck of pancreas by union of splenic , smv
2- tributaries
Rt, lt gastric veins
3- termination
By rt, lt terminal branches then to liver to ivc
Talk about splenic vein (4)
1- passes in lienorenal ligament
2- below its artery
3- unites with smv to give portal
4- tributaries
- left gastroepiploic
- short gastric
- pancreatic
- imv
Talk about smv
(3)
1- passes infront if 3 rd part of duodenum
2- joins the spenic to form portal
3- tributaries
- anteroinferior pancreaticoduodenal
- anterosuperior pancreaticoduodenal
- jejunal
- ileul
- iliocolic
- right colic
- middle colic
- right gastroepiploic
Talk about imv
(3)
1- ascends to posterior abdominal wall
2- joins the splenic vein behind the body of pancreas
3- tributaries
- left colic
