,Th e Esophagus
Surface Anatomy
Begins at C6
Passes Esophageal hiatus at T10
Ends in the Cardia at T10/T11

Name 3 constrictions
A: Cervical (origin)

B: Thoracic (broncho-aortic) crossed
by aortic arch & L main bronchus

C: Diaphragmatic: through E.Hiatus

Describe the blood supply to the
abdominal part of the esopahgus

,The Stomach

Surface Anatomy Relations
Regions
Cardiac Orifice
- 6th left costal cartilage, T11

Fundus
- Posterior to Fifth rib
- Midclavicular plane

Lesser & Greater Curvature
- From10th costal cartilage
- To pyloric antrum

Pylorus
- 9 (like a reverse P) costal cartilage
- L1 when supine (lying down)
- L2-L3 when erect

Less omentum
- Connects stomach & proximal
duodenum to liver.

Greater omentum
- Connects stomach & proximal
duodenum to transverse colon.

Connects stomach & proximal Pyloric Nodes
duodenum to the liver. Blood Supply:

GreaTer Omentum> CELIAC TRUNK
Connect stomach & proximal
duodenum to transverse colon
Common Hepatic
Left Gastric A
Left, Little, Less
Splenic A Lesser curvature
Joins right gastric A.
Proper Hepatic Gastroduodenal
Right Gastric A > Right gastroepiploic A > (snake-like)
Inferior part of < curvature greater curvature
Branches to stomach:
Left gastoepiploic: > curvature
