Breast - lymphatic drainage

The lymphatic and venous drainages of the breast are of great importance in the spread of carcinoma. 

About three quarters of the lymphatic drainage is to the axillary nodes: 

• Lymphatics pass around the edge of the pectoralis major and reach the pectoral group of axillary nodes; 
•  Routes through or between the pectoral muscles may lead directly to the apical nodes of the axilla; 
•  Lymphatics follow the blood vessels through the pectoralis major and enter the parasternal (internal thoracic) nodes; 
• Connections may lead across the median plane and hence to the contralateral breast; 
•  Lymphatics may reach the sheath of the rectus abdominis and the subperitoneal and subhepatic plexuses.

Details:

A lymphatic drainage massage is a type of full body massage that helps to unblock and drain the lymphatic system. These techniques can boost the immune system, reduce toxins, and help prevent breast cancer and other ailment. This type of massage can be done as part of a spa treatment or at home using some basic oil.

These videos are going into detail instructions on how Lymph massage works.

It should be noted that free communication exists between nodes below and above the clavicle and between the axillary and cervical nodes.

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

Details :

This is a short video illustrating the blood supply of the stomach coming from the Celiac trunk " which is the first branch of the Abdominal Aorta" .
3 major branches come from the Celiac Trunk: 1-Left Gastric. 2- Common Hepatic " which gives us the right gastric artery and Gastroduodenal artery- giving us the right gastroepiploic artery. 3- the Splenic " which gives us the left gastroepiploic".

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