The transverse colon begins to descend at the left colic (splenic) flexure The sigmoid colon immediately succeeds the descending colon The rectum and anal canal succeed the sigmoid colon Lab 11: The esophagus through the proximal duodenum is considered the foregut The mid-duodenum through mid-transverse region is considered the midgut The mid-transverse colon through rectum is considered the hindgut The Celiac Trunk supplies the foregut o The branches: Left gastric artery: supplies the lesser curvature of the stomach Splenic artery: supplies the spleen Pancreatic branches: supplies the body and tail of pancreas Short gastric arteries: supply fundus of stomach Left gastro-omental artery: supplies greater curvature of stomach Common hepatic artery Proper hepatic artery o Right gastric artery: supplies lesser curvature of the stomach
o Right hepatic artery: supplies right lobe of the liver o Left hepatic artery: supplies left lobe of the liver o Cystic artery: supplies the gallbladder Gastroduodenal artery o Right gastroomental artery o Anterior/posterior superior pancreaticoduodenal branches: supplies the duodenum and head of the pancreas The Superior Mesenteric artery supplies the midgut o Ileocolic artery: supplies the terminal ileum, proximal ascending colon, vermiform appendix, and cecum o Right colic artery: supplies the ascending colon o Middle colic artery: supplies the right colic flexure and proximal transverse colon The Inferior Mesenteric artery supplies the hindgut o Left colic artery: supplies the distal transverse colon and descending colon o Sigmoidal arteries: supplies sigmoid colon o Superior rectal artery: supplies upper rectum The right and left gastric arteries anastomose to the lesser curvature of stomach The right and left gastro-omental arteries anastomose to the greater curvature of the stomach The middle and left colic arteries anastomose to the transverse/descending colon All the abdominal veins drain into the hepatic portal vein o The hepatic portal vein drains in to the liver The major tributaries of the hepatic portal veins are: o Superior Mesenteric o Inferior Mesenteric o Splenic Vein The difference between the hepatic portal vein and hepatic vein o GI Tract and splenic veins drain in to the hepatic portal veins, which drains into the liver; nutrient rich blood o Hepatic veins drain the liver content blood into the inferior vena cava; deoxygenated blood The sagittal suture separates the two parietal bones The coronal suture separates the frontal bone from the two parietal bones The lambdoid suture separates the occipital bone from the two parietal bones The squamous suture (2) separates the parietal bone from the temporal bone The temporal bone articulates with the zygomatic bone via zygomatic process Mastoid process of temporal bone vs. styloid process of temporal bone The auditory nerves exist through the external acoustic meatus
