The temples are particularly sensitive due to a combination of a thinner skull structure and the presence of a major artery underneath. This makes the area vulnerable to injury and trauma.
Here's a breakdown:
-
Thin Skull: The temporal bone, which forms the temple area, is relatively thin and weak compared to other parts of the skull. This offers less protection to the underlying structures.
-
Middle Meningeal Artery: A significant artery, the middle meningeal artery, runs directly underneath the temporal bone. This artery supplies blood to the brain's meninges (protective membranes). Because it's located so close to the surface, a blow to the temple can easily damage this artery. Damage to this artery can lead to serious complications, including epidural hematoma (bleeding between the skull and the dura mater, the outermost layer of the meninges).
Because of these factors, even a moderate impact to the temple can cause significant damage and potential brain trauma.
