Document Summary

Axial skeleton: composed of, skull, vertebral column, thoracic cage, framework that supports/protects the brain, spinal cord, and organs, attachment site for muscles. Terminology suture: rigid joint between two bones sinus: air-filled cavities articulation: location at which two or more bones make contact. The skull: protect the brain, guard entrances to digestive and respiratory systems, houses special sense organs for smell, taste, hearing, balance, sight, made of 22 bones, cranium (8 bones, face (14 bones) Bones of the cranium (8: frontal bone -> forms forehead. Supra-orbital foramen -> hole above the eye orbit. Frontal sinuses -> makes bone lighter; produces mucus that cleans + moistens nasal: parietal bones (2) -> posterior to frontal bone cavities. Sagittal suture -> formed by interlock of parietal bones. Coronal suture -> articulation formed by parietal bones and frontal bone: temporal bones (2) -> form part of both sides of cranium and zygomatic arches. Zygomatic process of temporal bone (zp) (part of zygomatic arch)
