Fig. 8. Superior Laranryngeal Area of Head

To show the superior laranryngeal area (stipled) of Head. Modified from Head's original diagram.

In this connection it is interesting to recall Head's "superior laryngeal" area of hyperaesthesia: it is shown in fig.8, modified from Head's original diagram, and represents a cutaneous area which might very well correspond with the skin surface of the third arch, extended under the conditions just described. It would not be justifiable, of course, to do more than suggest here such a possibility, but it may be said that Head originally proposed (Brain, Vol.xvii,1894) on theoretical grounds an association of the area with the third postoral arch.
