HITCH COCK'S ANATOMY 



after receiving fibers from the facial, and there divide into 

 two branches, which are distributed in the irregular labyrinth 

 of the ear. 



591. Glosso-Pharyngcal —The glosso-pharynjeal makes 

 the ninth pair, and is sent to the mucous surface of the fauces, 

 tongue, tonsils, and mucous glands of the mouth. 



592. Par Vagi, or Pneumogastric— The tenth pair, par 

 vagurri) spring from the medulla oblongata, and after giv- 

 ing branches to several of 

 the cranial nerves, are dis- 

 tributed upon the heart, 

 lungs, stomach, and nearly 

 all the organs of the tho- 

 rax and abdomen. 



593. Spinal Accessory. 

 — The spinal accessory 

 takes its origin from the 



The Anatomy of the side of the Neck, 

 showing the Nerves of the Tongue. 1, 

 A Fragment of the Temporal Bone 

 containing the Meatus Auditorius Ex- 

 ternus, Mastoid, and Styloid Process. 

 2, The Stylo-Hyoid Muscle. 3, The 

 Stylo-Glossus. 4, The Stylo-Pharyn- 

 geus. 5, The Tongue. 6, The Hyo- 

 Glossus Muscle; its two portions. 7, 

 The Genio-IIyo-Glossus Muscle. 8, 

 The Genio-Hyoideus: they both arise 

 from the inner surface of the Symphy- 

 sis of the Lower Jaw. 9, The Sterno- 

 Hyoid Muscle. 10, The Sterno-Thyroid. 11, The Thyro-Hyoid, upon which the Thyro- 

 Hyoidean Branch of the Hypoglossal Nerve is seen ramifying. 12, The Omo-Ilyoid 

 crossing the Common Carotid Artery (13), and Internal Jugular Vein (14). 15, The Ex- 

 ternal Carotid giving off its Branches. 16, The Internal Carotid. 17, The Gustatory 

 Nerve giving off a Branch to the Submaxillary Ganglion (18), and communicating a little 

 further on with tne Hypoglossal Nerve. 19, The Submaxillary, or Wharton's Duct, 

 passing forwards to the Sublingual Gland. 20, The Glosso-Pharyngeal Nerve, passing in 

 behind the Hyo-Glossus Muscle. 21. The Hypoglossal Nerve curving around the Oc- 

 cipital Artery. 22, The Descendens Noni Nerve, forming a Loop with (23) the Commu- 

 nicans Noni, which is seen to be arising by filaments from the Upper Cervical Nerves. 

 24, The Pnenmogastric Nerve, emerging from between the Internal Jugular Vein and 

 Common Carotid Artery, and entering the Chest. 25, The Facial Nerve, emerging from 

 the Stylo-Mastoid Foramen, and crossing the External Carotid Artery.
