(a) Apex of lung (apex pulmonis). 



(b) Base of lung (basis pulmonis). 



(c) Costal surface (fades costalis) (0. T. outer surface of lung). 



(d) Mediastinal surface (fades mediastinalis) (0. T. inner surface of 



lung). 



(e) Diaphragmatic surface (fades diaphragmatica) . 



(f) Anterior border or margin (margo anterior}. 



(g) Inferior border or margin (margo inferior}, 

 (h) Hilus of lung (hilus pulmonis). 



(i) Root of lung (radix pulmonis). 

 (j) Cardiac impression (impressio cardiaca). 

 (k) Subclavian groove (sulcus subdavius). 

 (I) Interlobar incisure (indsura interlobaris) . 



The student should next pay attention to the differences 

 between the right lung and the left. Which is the larger! Which 

 is the shorter and wider ? Why should it be so ? 



In the right lung observe the form, position, and boun- 

 daries of 



(a) Superior lobe (lobus superior). 



(b) Middle lobe (lobus medius). 



(c) Inferior lobe (lobus inferior). 



In the left lung study 



(a) Superior lobe (lobus superior). 



(b) Inferior lobe (lobus inferior). 



(c) Cardiac notch (indsura cardiaca). 



(d) Lingula of lung (lingula pulmonis). 



Root of Lung (Radix pulmonis). 



Strip the pleura off the root of the lung ; study the relations 

 of neighboring structures to the root. Observe 



On both sides. 



In front of the root: 



(a) Anterior pulmonary plexus of N. vagus (plexus pulmonalis an- 



terior). 



(b) Phrenic nerve (N. phrenicus). 



(c) Pericardiacophrenic artery (A. pericardiacophrenica) . 

 Behind the root : 



(a) Vagus nerve (N. vagus) (0. T. pneumogastric). 



(b) Posterior pulmonary plexus of N. vagus (plexus pulmonalis pos- 



terior) . 

 Below the root : 



(a) Broad ligament of lung (ligamentum latum pulmonis). 

 On right side. 



(a) Azygos vein (V. azygos} (0. T. V. azygos major). 



(b) Superior vena cava (V. cava superior).
