The =stylo-mandibularis= is absent.
The =digastricus= has a tendinous origin on the paramastoid or styloid
process of the occipital bone; its bellies are short and thick. It does
not perforate the stylo-hyoideus. The two digastrici are connected
beneath the root of the tongue by a layer of transverse muscle-fibers
(Transversus mandibulæ).
