ANATOMY IN A NUTSHELL. 



421 



ior cervical ganglion is reddish-gray in color, about an inch and a half Long, 

 situated behind the internal jugular vein and the carotid artery and in front of 

 the Rectus capitis amicus major muscle. It is in front of the transverse pre- 

 ss : the second and third cervical vertebra-, sometimes a little higher and 

 sometimes a little lower, and the branches given off from this superior cervical 

 ganglion are rami efferent* s. 



LESSON CXX. 



1. Four gray rami to the first four spinal nerves. 



2. Branches to the twelfth cranial nerve and branch to the trunk of the 

 pneumogastric and nervus jugulaiis which divides, sending one branch to the 

 root of the pneumogastric and another to the petrosal ganglion of the ninth.

3. Four or five pharyngeal branches which unite with the ninth and 

 tenth cranial nerves making the pharyngeal plexus, and other branches to the 

 superior and external laryngeal nerves. 



4. Superior cervical cardiac nerve which is behind the carotid sheath, 

 behind or in front of the inferior thyroid artery, in front of the Longus colli 

 where it joins the cardiac branches of the tenth and middle cervical cardiac 

 branches of the sympathetic and recurrent and external laryngeal nerves. It 

 descends behind or in front of the right subclavian artery, along the innomi- 

 nate artery to the division of the trachea to enter the deep cardiac plexus. The 

 left one is in front of the left commoD carotid and the arch of the aorta, joining 

 the superficial cardiac plexus. 



5. The nervi molles are branches to the external carotid artery and its 

 subdivisions. They rive off subdivisions (a) to the internal-carotid artery.
