Q

What is the weakest point of the skull and why?

A

Pterion - Union of multiple bones (Sphenoid, temporal, frontal, and parietal), so weakest point.

  • Overlies the meningeal artery, so fracture can cause extradural haemorrhage.

Q

A
  • They allow a child to get through childbirth; the bones can move over the top of one another.
