RELATIONS IN THE ABDOMEN
• In the Abdomen, the esophagus descends for 1.3 cm and joins the stomach.
• Anteriorly, left lobe of the liver.
• Posteriorly, left crus of the diaphragm.
• Fibers from the right crus of the
diaphragm form a sling around the
esophagus.
• At the opening of the diaphragm,
the esophagus is accompanied
by:
– The two vagi
– Branches of the left gastric
vessels

• Cardia lies opposite the left seventh costal
cartilage (T10).
• Pyloric orifice lies on transpyloric plane (L1)
• Lesser curvature a curved line, concave to
the right joining these 2 points.
• The fundus: reaches to the left fifth
intercostal space.
• Greater curvature: is a curved line drawn
from the cardiac orifice to the summit of the
fundus, then downward and to the left,
finally turning medial toward the pyloric
orifice, passing through the intersection of
the left lateral with the transpyloric line.

Nerve Supply
• Sympathetic
• Parasympathetic
• Plexuses

Nerve Supply
• Sympathetic fibers: celiac plexus.
• Parasympathetic fibers: both vagi
i. Anterior vagal trunk:
• Formed from the left vagus
• Supply the anterior surface of thestomach
• Gives off a hepatic branch and fromit - a branch to the pylorus.
ii. Posterior vagal trunk:
• Formed from the right vagus
• Supply the posterior surface of thestomach
• Gives off a large branch to the celiacand the superior mesentericplexuses.
