36 OUTLINES OF ANATOMY. 



Sympathetic nerves, 863-4. (843-4) 



Gangliated cords of the sympathetic, 864-5-6-7-8. (844-5-6-7) 

 Cervical portion of the gangliated cord : 



Superior cervical ganglion, rami communicantes. 

 Branches: Ascending branch. 



(Carotid plexus) : 



Tympanic branch. Great deep petrosal nerve. 

 Branches to the Gasserian ganglion. 

 Branches to the sixth nerve. 

 (Cavernous plexus) : 



Communicating branches to the third, fourth, 

 and ophthalmic division of the fifth cranial nerves. 

 Sympathetic root of the lenticular ganglion. 

 Nervi molles. 



Communicating branches to the cranial nerves. 

 Pharyngeal branches. 

 Superior cervical cardiac nerve. 



Middle cervical ganglion ; rami communicantes ; ansa Vieussenii. 

 Branches: Branches to the thyroid body. 



Middle cervical nerve.

 Relations of the pharynx, 987. (965-6) 



Prevertebral Region. Articulations. 



Remove the sterno-mastoid, sterno-hyoid, sterno-thyroid, and the thyroid body. The structure of the 

 pharynx can be demonstrated to advantage only when separated from the spine and posterior portion 

 of the skull ; it is therefore necessary to divide the skull and remove the anterior portion with the 

 pharynx attached. Divide the trachea, oesophagus, and recurrent laryngeal nerves about an inch below 

 the larynx ; cut the common carotid artery about an inch below its termination ; divide the vagus and 

 sympathetic nerves at the same level. Draw the trachea and oesophagus forward, carefully separating 

 the pharyngeal walls from their prevertebral attachment. At the base of the skull, divide the perios- 

 teum and expose the basilar process between the pharynx and the prevertebral muscles; with the chisel, 

 divide the basilar process at this point, driving the chisel upward through the bone. With a narrow 

 saw, carry a cut inward on each side, along the posterior border of the petrous portion of the temporal 

 bone, passing just behind the jugular foramen, then curving forward on its inner side to the suture 

 between the basilar process and the petrous portion of the temporal bone, joining the first cut, made 

 with the chisel. Great care must be exercised not to injure the pharyngeal wall. The pharynx should 

 be wrapped in a cloth, moistened with preservative fluid, while the remaining structures of the pre- 

 vertebral region are exposed.
