C HAPTER IX. 
Plate XV — the digastric muscle. 
Fig. 1 and 2. The digastric muscle has its origin, a, at the lower 
part of the temporal hone; it runs downwards and forwards, and 
forms a strong, round tendon, &, which passes through a perforation 
in the stylo-hyoideus muscle, f; it is then fixed by a strong liga¬ 
ment, c, to the os hyoides, d; it again becomes fleshy, runs upwards, 
find is inserted into, e, the chin. This description differs from Dr. 
Paley’s, and it will be found by reference to dissections or the plate, 
that the os hyoides furnishes a stay or brace instead of a pulley 
and that the loop or ring is in the stylo-hyoideus muscle.
