Skull

The bones of the head, united at immovable sutures except the mandible, which moves at the temporomandibular joints. The cranium encloses the brain; the facial skeleton forms the face.

Key points

• 8 cranial + 14 facial bones.
• Sutures: coronal, sagittal, lambdoid.
• Pterion → middle meningeal artery → extradural haematoma.
• Middle cranial fossa = weakest (CSF otorrhoea).
• Membrane: vault + face. Cartilage: ethmoid, inferior concha. Mixed: occipital, sphenoid, temporal.
• Skull sutures: synarthroses.
• Skull flat bones: intramembranous ossification.
