What are the unpaired branches of the abdominal aorta from the anterior surface?
- Celiac trunk
- Superior mesenteric artery
- Inferior mesenteric artery
What is the unpaired branch of the abdominal aorta from the posterior surface?
The median sacral artery.
What supplies the Fore,mid, and hind gut?
- Celiac trunk (supplies the foregut)
- Superior mesenteric artery (supplies the midgut)
- Inferior mesenteric artery (supplies the hindgut)
What are the three main branches of the celiac trunk?
Left gastric artery
Splenic artery
Common hepatic artery
What are the branches of the splenic artery?
Pancreatic branches
Splenic branches
Short gastric branches
left gastroepiploic artery
What are the branches of the common hepatic artery?
A: Hepatic artery proper
right and left hepatic
right gastric
B: Gastroduodenal artery
Right gastroepiploic
Anterior superior pancreaticoduodenal artery
Posterior superior pancreaticoduodenal artery
What are the arteries that supply the stomach?
Short gastric branches (Splenic artery)
right and left gastric
right and left gastroepiploic
What arteries supply the duodenum?
Superior pancreaticoduodenal arteries
inferior pancreaticoduodenal arteries
The inferior pancreaticoduodenal arteries are a branch of what artery?
SMA
What are the branches of the SMA?
Common Inferior pancreaticodudenal artery
jeujnal and ileal branches
Ileocolic artery
Right colic artery
middle colic artery
What are the branches of the illeocolic?
Superior and inferior branches
====================================
From the arcade of the anastmoses of the inferior branch and SMA:
Colic branches
Anterior and posterior Cecal branches
ileal branches
apendicular artery
What happens to the superior branch of the ileocolic artery?
Anastmoses with the inferior branch of the right colic artery
What happens to the inferior branch of the ileocolic artery?
It anastmoses with the last part of the SMA
What are the two branches of the right and middle colic arteries?
Right: Ascending and descending branches
=========
Middle: Right and left branches
What does the name of the IMA change into?
after it crosses the left common iliac, its name changes into Superior rectal artery
What are the branches of the IMA?
Left colic, sigmoidal, and superior rectal
What does the ascending branch of the left colic artery anastamose with?
the ascending branch anastomoses with the left branch of the middle colic artery
What does the highest sigmoidal artery anastamose with?
The highest sigmoidal artery anastomoses with the descending branch of the left colic artery.
What is the marginal artery of drummond?
It is an anastmotic artery formed by the anastomeses between the various colic arteries
Where does the marginal artery begin and end?
t extends from the ileocecal junction to where it ends by anastomosing with the superior rectal artery.
What area in the marginal artery of drummond has low blood supply and what is it called?
The anastmotic branches between the left colic and middle colic arteries
Called: Avascular area of riolan
What is the Arterial supply of the rectum and anal canal
1. median sacral artery
2. superior rectal artery (inferior mesenteric)
3. middle rectal artery (internal iliac): the muscular wall only
4. inferior rectal artery
(internal pudendal)
What is the signficance of the middle rectal artery in males?
Supplies branches to seminal vesicles
What is the lymphatic drainage of the GIT?
Celiac nodes, inferior and superior mesenteric nodes (The preaortic lymph nodes lie in front of the aorta)
drain into the intestinal lymphatic trunk which will drain into the cisterna chyle (L1 &2) behind aorta (which also receives 2 lumbar trunks) →
to thoracic duct
