NERVUS FACIALIS, 467 



and to the integuments of the temple; they anastomose in their 

 distribution with each other, with the superficial and deep 

 temporal branches of the inferior maxillary nerve, arid with 

 the frontal and lachrymal branches of the ophthalmic. The 

 malar branches are primitively, also, two or three in number: 

 they cross the malar bone, dividing, subdividing, and anasto- 

 mosing again, and are spent upon the integuments and muscles 

 of this part of the face. They also anastomose with filaments 

 of the lachrymal nerve, and with those of the infra-orbitar 

 nerve. 



The Buccal Branches are three in number, sometimes two 

 only ; and pass across the masseter muscle under the skin. The 

 superior anastomoses with the temporo-facial, and the inferior 

 with the cervico-facial. The buccal branches supply the skin 

 and muscles of the face intermediate to the eye and to the low- 

 er lip. The numerous filaments into which they divide anas- 

 tomose frequently with each other, and with the branches of 

 the fifth pair, which appear about the same parts, as the exter- 

 nal and internal nasal nerve, the infra-orbitar, and so on. The 

 middle buccal is parallel with the duct of the parotid gland, and 

 adheres to it. 



The Cervico-Facial Branch descends in the substance of the 

 parotid gland, behind the ramus of the lower jaw; when it 

 reaches the angle of the latter it goes obliquely forwards, be- 

 neath the platysma myodes muscle. Though it sends off many 

 fasciculi, they may be referred to two divisions, a superior and 

 an inferior. The first crosses the inferior part of the masseter 

 muscle, and may be traced in its numerous distribution of fila- 

 ments, to the integuments arid muscles lying upon the body of 

 the lower jaw. These filaments anastomose with each other, 

 and with the mental branches of the inferior dental nerve. The 

 inferior division supplies the skin and the platysma myodes mus- 

 cle on the upper part of the neck along the base of the lower 

 jaw. Its filaments are joined by several coming from the an- 

 terior fasciculus of the third cervical nerve. 



The anastomoses of the facial nerve, derived from its own 

 branches and from those of the trigeminus, which reach the 

 face, are entirely too numerous for a detailed description of 

 them ; it, indeed, appears unnecessary to extend the latter be-
