pars

The insertion is tendinous on the dorsal surface of the lower mandible in common with the dorsal aponeurosis of pars profundus.

In one individual, a Mourning Dove, the origin of pars lateralis of M. pterygoideus dorsalis extended to the pterygoid.

The tendon of origin is actually one with the ventral aponeurosis of pars profundus, which is situated in a horizontal plane.

The latter usually increases the range in order to impede the strengthening of the enemy's foremost line, as explained in pars.

The pars facialis and frontal process of the maxilla are greatly reduced.
