and finally into the orbital septum and the internal muscles of 

 the eye. It commimicates with the ophthalmic nerve and sends 

 twigs to the lacrimal gland, the gland of Harder, the upper eyehd, 

 and the nose. The orbito-nasale ganglion is located where these 

 nerves communicate near the nasal region. The second branch of 

 the sympathetic caroticus cephaHcus is the inferior recurrent nerve. 

 This branch passes forward and dorsally from the pterygoid bone to 

 a point where the upper rim of the rising wings of the jaw bone meets 

 the sphenoid rostrum. In this course, some branches are given 

 off to the pharynx, one branch near the lacrimal gland, and a branch 

 which commimicates with the superior maxillary nerve just before 

 the nerve enters the jaw bone. The spheno-palatine ganglion is at 

 the point of fusion. 



The terminal branches of the spheno-palatine are distributed 

 to the hard palate, the nose, and the lacrimal gland. 



From the large cervical nerve ganglion and near the roots of the 

 caroticus cephaUcus are given off a few small nerve fibers which pass 

 alone to the pharynx or accompany the jugular nerve branches, and 

 fuse with the main trunk of the caroticus cephalicus nerve. 



From the large superior cervical nerve ganglion the sympathetic 

 trimk, extends downward toward the thorax. . It is covered deeply 

 with muscles. This portion is known as the cervical sympathetic 

 nerve trunk. A trimk Kes on each side of the cervical vertebrae. 

 The large thoracic nerve ganglion, the inferior cervical, is located 

 along this trunk at the entrance of the thorax. From this ganglion 

 there is given off the recurrent cardiacus which suppUes the heart. 

 The end branches of the sympathetic nerve trunk blend with the 

 pneumogastric nerve. The inferior nerve ganglion is the ganglion 

 cardiacum. Near this ganghon is found a nerve plexus in which 

 there are imbedded peripherlistic gangha. This thoracic plexus, 

 accompanying the collica artery, passes to the abdominal region, 

 supplying the intestines and taking part in the formation of the 

 abdoininal plexus. The abdominal plexus is located near the 

 anterior portion of the kidneys. Its fibers are directed mainly 

 downward to the visceral organs. The large intestine, the rectum 

 and the copulatory organs receive branches. These latter branches 

 take part in the formation of the pedimda nerve plexus. Some 

 branches of this plexus, follow the branches of the posterior mesen- 

 teric artery. 



The thoracic trunk (Fig. 64, No. 42) of the sympathetic is double.
