Facial Bone Structure
A common skeletal structu re 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.
•Bonestomaketheeyesopenandclose.
• A bone to cont rol 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.
