THE POCKET ANATOMY 



The deep surface is irregular, and lies on the styloid process 

 and its attached muscles, the internal jugular vein, the vagus, 

 spinal accessory and hypoglossal nerves, and is divided into 

 three lobes : 



The glenoid lobe fills up glenoid cavity behind Glaserian 

 fissure. 



The pterygoid lobe passes forwards internal to the ramus of 

 the jaw between the external and internal pterygoid muscles. 



The carotid lobe surrounds the styloid process, and lies 

 between the external and internal carotid artery. 



The socia parotidis is a separate lobe projecting from the 

 anterior surface. 



Relations of the Socia Parotidis : 



Above. Below. 



Zygoma. Duct. 



Cervico-facial divi- 

 sion of facial nerve. 



Internally. 

 Masseter. 

 Transverse facial 

 artery. 



The duct (Stenson's) is 2 inches long ; comes off from the 

 anterior border and crosses the masseter to pierce the 

 buccinator and buccal mucous membrane. Its opening in 

 the mouth is opposite the 2nd upper molar tooth. 



Course of the duct: line from bottom of lobule of ear to 

 middle of upper lip. The transverse facial artery lies above 

 the duct, and the buccal branches of the yth nerve below. 



The parotid gland is traversed by the following, of which 

 the arteries lie deep and the nerves most superficial. 



Veins. Nerves. 



Internal maxillary. Facial. 

 Temporal. Auriculo-temporal. 



Temporo-maxillary . Facial of great auri- 

 cular. 



Arteries. 



External carotid. 

 Posterior auricular. 

 Internal maxillary. 

 Superficial tem- 

 poral. 

 Transverse facial. 



Nerve supply of gland : sympathetic and glosso-pharyngeal. 

 The latter branch may be traced as follows : The tympanic 

 (Jacobson) branch gives off small superficial petrosal, which 

 passes through otic ganglion and joins the auriculo-temporal 

 trunk, thus supplying the gland. 



THE SUBMAXILLARY GLAND lies under cover of the body oi 

 the lower jaw. 



Superficial lobe: separated by stylo - maxillary ligament 

 from parotid, grooved above and behind by facial artery.
