frontal bone

anterior portion of the cranium and roof of orbits
supraorbital foramen provie passage for blood vessels that supply the eyebrow, eyelid, and frontal sinuses;
frontal sinuses
coronal suture

2

parietal bone

form part of the superior and lateral surface of the cranium; sagital and squamous sutures

3

occipital bone

the posterior and inferior surface of cranium;
occipital condyle- site of articulation b/t skull and atlas
foramen magnum- hole for spinal cord
lamboidal suture

4

temporal bone

part of lateral walls of cranium and zygomatic arches; only articulation with the mandible;
mastoid process- attachment point for muscles that rotate and extend the head
zygomatic process-cheekbone
styloid process- support hyoid bone
