Which artery passes deep to the marked area in the given image:
Deep temporal Artery
Middle meningeal Artery
Anterior cerebral Artery
Internal Carotid Artery
Answer B. Middle meningeal artery
- The pterion is the region where the frontal, parietal, temporal, and sphenoid bones join together.
- It is located on the side of the skull, just behind the temple.
- It is the junction between four bones:
- the parietal bone
- the squamous part of the temporal bone
- the greater wing of the sphenoid bone
- the frontal bone
- The pterion is known as the weakest part of the skull.
- The anterior division of the middle meningeal artery runs underneath the pterion.
- Consequently, a traumatic blow to the pterion may rupture the middle meningeal artery causing an epidural hematoma.
