angle of His
where the fundus meets the GEJ
the gastric blood supply
Lt, Rt gastric a.—-lesser curvature
Lt, Rt gastroepiploic a.—-greater curvature
what neuro-vascular structures might be in the gastrohepatic lig?
- an aberrant branch from left gastric a.
- a branch from anterior (left) vagus
what is the left gastric vein also called?
coronary vein
which gastric veins drain into the portal vein?
Lt, Rt gastric v.
which gastric veins drain into the splenic vein?
Lt gastric v., Lt, gastroepiploic v
which gastric veins drain into the SMV?
Rt gastroepiploic v.
what is the criminal nerve of Grassi?
The branch which the posterior vagus sends to
the posterior fundus
why is it termed the criminal nerve of Grassi?
arises above the esophageal hiatus and is easily missed during truncal or
highly selective vagotomy.
describe anterior nerve of Laterjet
anterior (left) vagus continues along the lesser curvature as the anterior nerve of Laterjet.
posterior vagus
right vagus sends branches to the
celiac plexus and continues along the posterior lesser curvature
the “crow’s foot” near the angularis incisura
The ant. nerves of Laterjet terminateas the “crow’s foot,” sending branches to the antro-pyloric region.
origins of extrinsic sympathetic nerves
spinal levels T5–T10
characteristics of gland histology in the gastric antrum
-more branched and shallow
-parietal cells are rare
-gastrin-secreting G cells and somatostatin-secreting D cells are
present
a normal stomach consists of epithelial cells:
- oxyntic (parietal) cells,
- chief (zymogenic cells),
- mucous cells,
- endocrine cells.
gastric rugae consist of
The mucosa and submucosa
