	Step 1: Begin with the skull.


	The juncture of the frontal, sphenoid, parietal and temporal bones form the "pterion", which is behind the zygomatic arch. A skull fracture in this area has the potential to damage intracranial blood flow. Which intracranial artery is directly behind the pterion?
The middle meningeal artery lies under this area. If injured, the bleeding can lead to a life threatening extradural hematoma .


	Step 2: Using the Highlight tool, locate and identify each of the major bones of the skull listed below:
	Frontal bone Nasal bone Lacrimal bone Ethmoid bone Vomer Maxilla Sphenoid bone Zygomatic bone Mandible Parietal bone Temporal bone Occipital bone	🔍 Tap on each image to enlarge:
