EXPLANATION
OF
PLATE I.
BEING A VIEW OF THE NERVES OF THE HEAD.
In this plate the two distinct classes of nerves which go to the face
are represented; the one to bestow sensibility, and the other for
the motions of speaking and expression, that is, the motions connected
with the respiratory organs.
The nerves on the side of the neck are also represented. These
I have discovered to be double nerves, performing two functions;
they control the muscular frame, and bestow sensibility upon the
skin. Besides these regular spinal nerves, which are for the common
endowments, the nerves of the throat are represented. These
latter nerves are the chords of sympathy, which connect the motions
of the neck and throat with the motions of the nostrils and lips;
not merely during excited respiration, but in the expression of
passion.
