SECTION VI. 



THE FASCLE OF THE NECK. (CERVICAL FASCLE.) 



The fasciae of the neck are divided into the superficial 

 and deep cervical. 



The superficial cervical fascia is situated immediately 

 beneath the integuments, enclosing the platysma myoides, 

 and sometimes so closely connected to this muscle, as to be 

 with difficulty separated from it. It is continuous with the 

 superficial fascia of the abdomen and chest, and attached 

 to the sternum and clavicle. It is traced over the lateral 

 and anterior parts of the neck, ascending to the jaw with 

 which it is connected, and expanding over the parotid 

 and sub-maxillary glands, it sends processes into the sub- 

 stance which surrounds their several lobules. It then pro- 

 ceeds upward to form a strong attachment to the cartilage 

 of the ear, mastoid process, and zygoma. It forms the an- 

 terior layer of the sterno-mastoid, becomes weak at the 

 lateral and posterior portions of the neck, gives a covering 

 in front and behind to the trapezius, and is traced into the 

 fascia profunda or deep cervical fascia. 



Indeed, this latter fascia is regarded as nothing more than 

 the reflected portion of the deep surface of the superficial 

 cervical, and, so considered, it is found to pass from the su- 

 perficial along the anterior margin of the sterno-mastoid, go- 

 ing behind this muscle, the omo-hyoid and trapezius, back 

 to the ligamentum nuchae, which some regard as its origin. 

 In front it is connected to the larynx and thyroid gland, 

 invests the sterno-hyoid and sterno-thyroid muscles, forms 

 sheaths for the other muscles, as well for the vessels and 

 nerves, and at the inferior part of the neck is attached to 

 the inter-clavicular ligament and upper posterior margin 

 of the sternum, adjacent to the clavicle and first rib. At 

 this point, the root of the neck, some loose fatty matter is
