one to the sternomastoid is of some size and is the only 

 one named. 



The remaining branches of the occipital are given on 

 page 130. 



(5) The Posterior Auricular Artery : See Dissection of 

 the Face, page 65. 



This is the second branch from the back of the external 

 carotid. It is given off just above the occipital, runs up- 

 ward and backward between the spinal accessory and facial 

 nerves, and through the parotid gland to the groove 

 between the external auditory meatus and the mastoid 

 process, and supplies branches to the ear and the scalp 

 behind it. From the posterior auricular is given off the 

 stylomastoid branch which enters the foramen of that 

 name. 



(6) The Ascending Pharyng-eal : This is the first branch 

 of the external, and comes off in the angle between it 

 and the internal carotid. 



It is a long, slender artery, which runs upward between 

 the pharynx, internal carotid, and spine to the base of the 

 skull. It supplies fine branches to the pharynx, front of 

 the spine, palate, and posterior meningeal, which reach the 

 interior of the skull through the middle lacerated, jugular, 

 and anterior condyloid foramina.
