    • Side 3
    • what is the falciform lig?
    • splits the liver in half
    • what is the falciform lig dervied from?
    • fetal umbilical vein
    • what is the hepatoduodenal lig?
    • connect the liver to the duodenum
    • what significanct structures does the hepatoduodenal lig contian?
    • portal triad
    • what makes up the portal triad?
    • hepatic artery, portal vein, common bile duct (HPC)
    • what are the layers of the gut wall? (inside out)
    • mucosa, submucousa, muscularuis, advantitia
    • In what layer do you find the submucosal plexus?
    • submucousa
    • in what layer do you find the myenteric plexus?
    • muscularis layer.
    • what is the muscle anatomy of the esophogus from proximal to distal?

      Why
    • upper 1/3- skeletal
      middle 1/3- smooth and skeletal
      lower 1/3- smooth

      this is transitioning from voluntary control to visceral control.
    • In what part of the esophogus would you fing squamous CC
    • middle 1/3
    • what section of the esophogus would you find adenocarcinoma?

      Why?
    • in the lower 1/3

      this is due to barrets esophogus from chronic GERD.
    • what makes up the foregut
    • the stomach to 1/2 the diuodenum

      liver, gallbladder, pancrease, spleen
    • what artery supplies the foregut

      (main artery)
    • Ciliac artery
    • what nerve supplies the foregut?
    • vagus
    • what makes up the midgut?
    • the distal half of the duodenum to just before the splenic flexture
    • what artery supplies the midgut?

      (main artery from Aorta)
    • the SMA
    • what nerve innervates the midgut?
    • vagus
    • what makes up the hindgut?
    • splenic flexture and beyond
    • what artery supplies the hindgut?
    • IMA
    • what nerves supply the hindgut?
    • PNS from the pelvis
    • what are the branches of the celiac artery?
    • common hepatic artery
      splenic artery
      left gastric artery
    • where does the right gastric artery branch from?
    • the common hepatic artery?
    • what 2 arteries supply the lesser curvature of the stomach?
    • the right and left gastric artery
    • what artery does the spleen use as an ananstomosis is the splenic artery is blocked?

      where does this anastomosis gets its blood from?
    • the short gastric arteris

      anastomosis with left gastropeploic artery,
    • what arteries allow for collateral blood flow is the abdominal aorta is blocked? (3)
    • Internal thoracic artery
      superior pancreaticoduodenal artery (celiac artery)
      middle colic artery (SMA)
      superior rectal artery (IMA)
    • where do you get internal hemroids?
    • above the pectineal line
    • where do you get external hemrrohids?
    • below the pectineal line
    • why are internal hemmroids non-painful and extrnal hemrroids are?
    • internal hemroids are above the pectineal line which is innnervated by visceral nerves and what is below the pectineal line is innervated by the somatic nerves
    • which type of hemroids is most commonly associated with portal HTN?
    • internal hemroids
    • when portal HTN occurs, what are the 3 arteries that is uses in order to allow for collateral blood?
    • the esophogeal arteries (esophogeal varacirs)

      paraumbilical arteries (caput madusae)

      superior rectal artery (internal hemroids)
    • what artery supplies tissue above the pectinate line?
    • the superior rectal artery
