ANATOMY IX A NUTSHELL.

vessels run with the blood vessels along the bronchi. The lymphatics of the 

 Lung empty into the bronchial nodes, which lie around the bifurcation of the 

 trachea and the root of the lung. Several efferenl vessels pass from these nodes 

 to the tracheal nodes and oesophageal nodes at the root of the neck, and those 

 on the right side empty into the right lymphatic duct, while those on the left 

 side empty into the thoracic duct. 



The superficial cardiac lymphatic vessels lie on the surface of the heart in 

 the subserous or areolar tissue, while the deep cardiac lymphatic vessels lie in 

 the deeper tissues. These vessels accompany the coronary vessels. Those of 

 the right side uniting at the root of the aorta from which place they pass upward 

 over the arch of the aorta along the trachea to the right lymphatic duct. Those 

 of the left side unite at the base of the heart and pass along the pulmonary artery 

 to nodes at the root of the arota. and after ascending along the trachea pass into 

 the thoracic duct. 



The thymic vessels pass into the internal jugular veins from the under sur- 

 face of the thymus gland. 



The lymphatics of the oesophagus, after communicating with the posterior 

 mediastinal nodes, end in tin 1 thoracic duct. 



LESSON CLXVII. 



The superficial lymphatic vessels of the scalp are as follows: (1) Pos- 

 terior or OCCIPITAL vessels which follow the course of the superficial veins

downward over the occipital bone to the occipital nodes. These node- are also 

 called suboccipital and are situated just below the superior line curved of the 

 occipital bone. Their radicles are from the back of the bead, and the vessels 

 from these nodes empty into the superficial Lymphatic nodes of the neck. In 

 secondary syphilis these nodes arc enlarged. (2) POSTERIOR AURICULAR (pos- 

 tero-lateral) vessels pass downward behind the ear toend in the postero-auricu- 

 lar nodes, also called Sterno -mastoid. These nodes are situated over the in- 

 sertion of the Stemo -cleido-mastoid muscle. The vessels which Leave these 

 nodes empty into the superficial cervical. (•"») Temporal lymphatic vessels, 

 also called antero-lateral, pass with the superficial temporal veinand end in the 

 parotid lymphatic nodes. These nodes are situated over the parotid gland
