PLATE 2 
EXPLANATION OF FIGURE 
7. Male Chinese II. The platysma is coarsely bundled and forms an entire 
plate. Its upper part extends above the mouth-angle meatus line toward the 
zygomatic; the inferior part passes under the triangularis. The triangularis, 
together with the M. risorius, forms a fan-formed muscle mass; some inter- 
mediate bundles between the two muscles extend to the platysma. At its origin 
the zygomaticus is overlaid by and partially interlaced with the orbicularis 
oculi. Strong radiating and often crossing bundles on the lateral part of the 
orbicularis oculi are striking. Marginal bundles from the auriculofrontalis 
radiate upward; the curved lateral fibers interlace with ascending platysma fibers. 
Those running ventrad extend farther on the zygomaticus, even to the quad- 
ratus labii superioris. The lower medial bundles are also well developed; the 
superficial layer is transected in the illustration and the deep portion passes 
under the lateral marginal bundle and then interlaces with the cervical part of 
the platysma. The laterally directed marginal bundles of the orbicularis oculi 
lie deep between it and the ear, and are visible in the plate through an artificial 
opening. The M. frontalis is connected laterally with the higher auricularis 
bundles. The auriculofrontalis runs between the two muscles, joins the auricu- 
laris anterior, and continues forward and upward to the lateral part of the 
frontalis. The temple is also well muscularized. The extent of the occipitalis 
is noteworthy; the posterior bundles are more vertical and the anterior incline 
more forward and reach the auricularis superior. At last they unite trans- 
versely with the auricularis posterior. The auricularis is inclined forward and 
downward and consists of four parts, not readily separable. The cervical part 
of the platysma is broadly extended under the ear, the hinder limb approaches 
the median line above the insertion of the sternocleidomastoid; the anterior 
diverges at the hinder part of the cheek region of the platysma. Some bundles 
of the latter ascend further and cross the diverging bundles of the orbicularis 
oculi.
