Document Summary
The components of the axial skeleton and their specific function: noting prominent articulations and landmarks. The axial skeleton forms the vertical axis of the body. It consists of 80 bones that include, 29 skull and associated bones, 25 thoracic cage bones and 26 vertebral bones.

Bony landmarks: bony openings = foramen: rounded opening or passageway through bone for blood vessels or nerves, depressions: fossa= shallow depression. The composition of the cranium and the face: general function, articulations, regions/landmarks. Cranial bones: parietal x2, temporal x2, occipital x1, frontal x1, sphenoid x1, ethmoid x1. General function: form part of the superior and lateral surfaces of the cranium. Articulations: articulate with one another, the occipital, temporal, frontal and sphenoid bones. Regions/landmarks: superior and inferior temporal lines = attachment site for the temporalis muscle.
