THE CRAXIAL NERVES. 



((■') Articiihn- hranch. — The nerve to the temporo-maxillary articnlntion comes 

 from one of the preceding- branches, or dii-ectly from the anriculo-temporal 

 nerve. 



(/) Trmporal hranclu-x — One of these, the smaller and jim^ferior of the two, 

 distributes filaments to the attrahens amiculam muscle, the vipper part of the 

 jiinna and the integument above it. The anterior temporal branch extends with 

 the superficial temporal artery to the top of the head, and ends in the integument. 

 It is often united -^-ith the temporal branch of the upper maxillary nerve. Meckel 

 mentions a communication between this branch and the occipital nerve. 



Lingual Nerve. — The.lingnal branch (or gustatory nerve), descends 

 nndcr cover of the external pterygoid muscle, lying to the inner side 

 and in front of the dental nerve, and sometimes united to it by a cord 

 which crosses over the internal maxillary artery. It is there joined at 



FifT. 340.

The zygoma and ramus of the jaw have been removed, and the outer ijlate of the jaw 

 taken off, so as to open up the dental canal ; the lower part of the temporal muscle has 

 been dissected otf the bone, and the masseter muscle turned down. 



1, I\Iasseteric branch, descending to the deep surface of the muscle ; 2, a twig to the 

 temporal muscle ; 5, anterior, and 7, posterior deep temporal neiwes ; .3, buccal ; 4, its 

 union with the facial ; 6, filaments given by the buccal to the external ptervgoid muscle ; 

 8, auriculo-temporal nerve ; 9, its temporal branches ; 10, its anterior auricular branches; 

 11, its union with the facial ; VI, gustatory or lingual nerve ; ]3,mylo-hyoid nerre ; 14, 

 inferior dental neive ; 15, its twigs supplied to the teeth; 16, mental branches ; 17, 

 branch of the facial uniting with the mental.
