Biventer

Thus muscles are named that have two bellies, from bis and venter; also digastricus.

Biventer musculus. It arises from the processus mastoidaeus. Its tendon frequently joins the stylohyoi-dseos and the membranous ring fixed to the os hyoidaeus, and is then attached to the inner part of the chin. It depresses the jaw, and thus opens the mouth. It is fleshy at both its extremities, and tendinous in the middle. The middle tendon passing through the aponeurotic ligament as the lateral part, and the root of the cornua of the os hyoides, is what renders it capable of performing its office. The ancients called it graphoides.
