- The skull is composed of several separate
bones (22 bones) united at immobile
joints called sutures.
-The connective tissue between the bones
is called a sutural ligament
Only one moveable bone, the mandible
which is united to the skull by the mobile
Temporomandibular Joint

The zygomatic bone has:
Frontal process: articulates
with frontal bone
Temporal process:
articulates with zygomatic
process of the temporal bone
to form the zygomatic arch
Maxillary process:
articulates with the maxillary
bone
Orbital plate: forms part of
the lateral wall of the orbit
