Identify the four major sutures of the cranial cavity. 12. Identify the foramina through which all cranial nerves and major vessels are trans- mitted. Bones of the Cranial Cavity (L.O. 8) Eight bones that make-up the cranial cavity and form a box to protect the brain. Bones are paired (2) and some are single (1). Bones are individual but are tightly joined by fibrous tissue forming immovable joints be- tween the bones called sutures. Illustration Demonstrating the Bones of the Cranial Cavity (Lateral View) 1

Good example is the orbit (formed by more than one facial bone) that protects the eye. There are many bones of the face and they are mostly small and fit into a complex mo- saic.
