Description
"Of the Muscles of the Lower Jaw.
Five Pair of Muscles are employ'd in the Motion of the Lower Jaw: Four of which were described by Vesalius and the preceding Anatomists; but for the Discovery of the fifth we are obliged to Falloppius. To these Riolan adds a sixth Pair, namely the Quadrati Genarum, which we have already described among the Muscles of the Cheeks and Lips" (Cowper, 1724, Chap. XVIII).
