The human skull is composed of 8 bones, and the weakest point is not a particular bone, but the wing point in the temporal fossa, which is the intersection of the frontal bone, parietal bone, temporal bone and butterfly bone, forming an “H” shaped bone seam. This is the weakest point of the lateral wall of the cranial cavity, and the inner surface of the cranial cavity has the anterior branch of the middle meningeal artery. In the apparent anatomy, this is the location of the temple of the human head. Due to the weakness of the bone here, it is protected by the overlying temporalis muscle as a cushion.
