and functions of the nerves. 411 
nerves go in both directions; branches of the seventh are 
sent to the membrane of the nose, and to the muscles at the 
back of the palate ; while branches of the fifth nerve ( and 
also of the sympathetic nerve) are brought into the interior 
of the ear. 
By the second of these communications, the corda tympani , 
[which joins the lingual branch of the fifth, just where that 
nerve is passing by the side of the levator and circumf exus 
palati,~\ the branches of this respiratory nerve have access to 
the velum palati and its muscles. 
The respiratory nerve of the face, emerging through the 
stylomastoid foramen, divides into many branches, and these 
diverging, spread to all the side of the face. First, a branch 
is sent to the muscles of the outward ear ; another is sent, 
under the angle of the jaw, to the muscles of the throat. The 
principal nerve then passes through the parotid gland and 
comes upon the face. Here the branches continue to scatter, to 
go upwards upon the temple, and downwards upon the side of 
the neck, forming on the neck a superficial plexus. The 
principal branches, however, go forward to the muscles of 
the forehead and eyelids ; a branch called superior facial is 
sent to the muscles of the cheek and the side of the nose ; 
while an inferior facial branch is given to the angle of the 
mouth and the muscles which concentrate there. 
In this extensive distribution, the nerve penetrates to all 
the muscles of the face : muscles, supplied also with the 
branches of the fifth pair. Its branches penetrate to the skin, 
accompanying the minute vessels of the cheek. 
The descending or inferior divisions, which go under the 
lower jaw and to the superficial muscles of the throat and
