Blood supply of stomach

The stomach is supplied by many arteries like :

1- short gastric arteries - branches of the splenic artery - supply the fundus of stomach

2-left gastro epiploic artery - branch of the splenic artery - supply the greater curvature of the stomach .

3- left gastric artery which is a direct branch of the coeliac trunk that arises from the aorta . supplies the lesser curvarture.

4- right gastric artery which is a branch of the common hepatic artery - supplies the lesser curvature.

5- right gastro epiploic artery which is a branch of the gastro duodenal artery which is again a branch of the common hepatic artery- supplies the greater curvature

--------------------------------------

The branches of the COELIAC TRUNK are :

1-common hepatic artery

2-left gastric artery

3-splenic artery

--------------------------------------

The branches of splenic artery are:

1-short gastric branches

2-left gastro epiploic artery

--------------------------------------

The branches of the common hepatic artery are :

1-hepatic artery proper

2-right gastric artery

3-gastroduodenal artery

-------------------------------------

The branches of the gastroduodenal artery are :

1-right gastro epiploic artery

2-superior pancreatico duodenal artery

-------------------------------------

P.S: The INFERIOR PANCREATICO DUODENAL ARTERY is a branch OF THE SUPERIOR MESENTRIC ARTERY .

Lymph nodes of Neck

*The lymph nodes of the neck can be divided into six levels within the defined anatomic triangles. These groups and the areas that they drain are particularly important when locating and working up a "neck mass" or possible malignancy. The groups and drainage areas are as follows:

I--Submental and submandibular nodes
II--Upper jugulodigastric group
III--Middle jugular nodes (draining the nasopharynx and oropharynx, oral cavity, hypopharynx, larynx.
IV--Inferior jugular nodes draining the hypopharynx, subglottic larynx, thyroid, and esophagus.
V-- Posterior triangle group
VI--Anterior compartment group
