Structure
Dr.Sherif Fahmy
Sympathetic ganglion
Dr.Sherif Fahmy
Branches- Rami communicants to
corresponding intercostal nerves.- To autonomic plexuses in thorax.- To aorta.- To abdominal organs through
splanchnic nerves.Dr.Sherif Fahmy

Applied Anatomy1- Spinal anesthesia at high level may lead to temporary drop of blood pressure.2- In case of essential hypertension, cutting of sympathetic chain between T2 & T5 will lead to drop of blood pressure.

Autonomic Plexes(Page 136)
1- Pulmonary Plexuses.2-Oesophageal plexuses.3- Cardiac plexuses (superficial and deep).

Lymphatic Drainage
Dr.Sherif Fahmy
Dr.Sherif Fahmy
Thoracic Lymph Drainage
A- From Chest wall.B- From thoracic contents.
Dr.Sherif Fahmy
A- From Chest Wall1- Superficial lymph vessels:- From front of chest to pectoral lymph nodes, parasternal or lower deep cervical lymph nodes.- From back of chest to subscapular nodes. Dr.Sherif
Fahmy
2- Deep lymph vessels:A- From anterior chest wall to parasternal nodes.B- Posterior part of chest wall to intercostal lymph nodes (opposite neck of ribs).C- Four diaphragmatic nodes (anterior, posterior and 2 lateral) which drain diaphragm and liver.Dr.Sherif
Fahmy
B- from Thoracic Contents
1- Anterior mediastinal nodes.2- Posterior mediastinal nodes.3- Nodes of lungs, bronchi and trachea.
Dr.Sherif Fahmy
•Lymph vessels from: -Anterior mediastinal nodes.-Tracheal lymph nodes.-Parasternal lymph nodes.Will unit together to form broncho-
medistinal lymph vessels which joins thoracic duct on left side and right lymphatic duct in right side.

Tributaries of Thoracic Duct1- Lymph from intestine, abdominal wall and lower limb through cisterna chyli.2- Left broncho-mediastinal lymph vessels.3- Left subclavian lymph vessels.4- left jugular lymph vessels.5- posterior mediatinal lymph nodes.
