Facial Bone Structure
A common skeletal structure for the face includes:
■ Bones to make the upper and lower lips open and close.
■ Bones to push the outer corners of the mouth, as for a smile.
■ Bones to make the eyes open and close.
■ A bone to control the jaw opening and closing.
■ The main head bone going straight up from the neck to the top of the
head. This bone controls the head overall, and any vertices not affected
by bones on the eyes, mouth and jaw. Use this bone to bend the head
forward or backward.
