GLANDS OF THE NECK. 523 



found between the superficial and deep cervical fascia. 

 Between the trapezius and sterno-mastoid, the deep cervical 

 fascia presents the cellular appearance. At the angle and 

 base of the jaw to which it is connected, it dips down deep 

 to be attached to the styloid process, forming the stylo- 

 maxillary ligament, and the partition between the parotid 

 and sub-maxillary glands. At this superior part we find 

 the two cervical fascise enclosing the parotid, absorbent 

 glands, and considerable cellular structure. Hence, when 

 inflammation is set up, and matter is formed, from the un- 

 yielding and resisting nature of these fasciae, the suffering 

 is increased, and the function of deglutition, together with 

 the movements of the jaw materially interrupted. 



The uses of the cervical fasciae are to confine and support 

 the several muscles, vessels, and glands ; and at the lower 

 part of the neck, according to the experiments of Mr. Law- 

 rence, to protect the trachea from the pressure of the atmos- 

 phere during inspiration. 



Lymphatic Glands of the Neck, (cervical glands) The 

 lymphatic glands belong to the conglobate division, and 

 form part of the absorbent system. This system performs 

 the function of absorption, and consists of the lacteals, lym- 

 phatic vessels, and lymphatic glands. The glands have 

 already been summarily described under the head of the 

 glandular tissue. It is only necessary for us here, there- 

 fore, briefly to recapitulate the lymphatic or cervical glands 

 of the neck. 



These are divided into the superficial and deep. The 

 former are seen along the posterior margin of the sterno- 

 cleido-mastoideus, lying scattered between this muscle and 

 the trapezius, and in connection with the external jugu- 

 lar vein. The deep glands are large and numerous and form 

 a chain descending tbe neck, in company with the carotid 

 vessels, from the angle of the jaw to the chest. They are 

 also connected with the pharynx, oesophagus, larynx, and 

 thyroid gland, and with the glands of the face above and 

 the thorax below. Through both the superficial and deep 

 get of glands, the lymphatics of the head and neck pass.
