Mediastinal part of right and left lung

Mediastinal part of lung:

the impression and relation of mediastinal surface differ in two lungs

Mediastinal surface of right lung:

Cardiac area is related with   Anterior surface of Right auricle, Anterior and right surface of right atrium,  Part of anterior surface of right ventricle  

In front of hilum upper part : Groove for SVC

In front of hilum lower part groove for  IVC are present

Above the hilum : groove for azygous vein

Behind the hilum : osophagus except upper and  lower part

From apex to groove for azygous vein:Anterioposteirly

Right brachiocephalic vein,Trachea,Osophagus

Three neural structures:right phrenic nerve, Right vagus nerve, Right sympathetic chain

Mediastinal surface of left lung

Cardiac area is related withAnterior and left surface of left ventricle and left auricle, Anterior surface of a part of the right ventricle

In front of hilum : upper part impression for ascending aorta

Just below and little in front  the ascending aorta , the impression for pulmonary trunk is present

Above the hilum : arch of aorta

Behind the hilum: descending thoracic aorta and osophagus present just above  and below the descending aorta

So osophagus is related twice with the left lung  

From apex to groove for arch of aorta  

Anterioposteirly

Left common carotid arter,Left subclavian artery,Trachea,Osophagus,Thoracic duct

Four neural structures

Left  phrenic nerve

Left  vagus nerve

Left recurrent laryngeal nerve

Right sympathetic chain
