The Head
Skull and Bones of Face (Plate 20).
The front and side form of the skull is given on Plate 20. From the top of the head to the eyebrow is called " skull," and from there to the chin is called the " face."
There are two muscles on the temple of the forehead which attach to the bone in the middle of the latter. This
gives a slight depression there, which continues down between the eyes and runs along to the bridge of the nose. These simple muscles cause a slight prominence in front, but fall away into the side plane of the head.
The eye socket at 1 is at an angle not seen when fully fleshed, the muscle "orbicularis palpebrarum " overlapping at a different angle.
The bone of the nose does not run to the tip (see Fig. 2), but leaves off half-way down. It is clothed on each side by the muscle " compressor naris " terminating in cartilages which form the wings and tip.
A muscle runs completely around the lips, overlapping a large portion of the side teeth, leaving a small opening for the lips.
The cheek-bone has muscles running across, the largest being the " masseter," which controls the movement of the jaw in eating, speaking, etc. When the face is very thin, as in the case of extreme old age, the cheek-bone shows prominently and gives a haggard look.
In the profile view of the skull, only the lower front is termed the " face."
Note the flat plane on the side of head which is occupied by the " temporalis " muscle. The neck muscles connect to the head at space 5, starting just behind the ear position.
