Human Skull. Human Skull – 22 bones 2 parts: 1.Cranium (8 bones fused at sutures) – protects brain, provides muscle attachment, sinuses reduce weight.

CHAPTER # 7(a) THE SKELETAL SYSTEM.

Skull Usually consists of 22 bones, all of which (except the lower jaw) are firmly interlocked along lines called “sutures”. Cranium = 8 bones Facial skeleton.

THE SKULL SIMPLY, AMAZING!. Most complex bony structure 22 bones in all Mostly flat bones, but not all!
