What tactile bone marks are there on the skull?

Mastoid process: located below the external ear, there is a stem-like mastoid process in front of the front edge of its root, from which the facial nerve exits the skull. The second half of the deep surface of the mastoid is the sigmoid groove. Lower collar angle: it is the turning point between the posterior edge of mandibular branch and the lower edge of mandibular body, where the bone is thin and easy to fracture. External occipital protuberance: the most prominent protuberance located in the occipital region, whose deep surface is sinus confluence. Zygomatic arch: located on the same horizontal plane as the connecting line between the lower orbital margin and the extraoccipital protuberance, and the parotid duct is located at the lower transverse finger. Wing point: it is the junction of parietal bone, frontal bone, sphenoid bone and temporal bone, 3~4cm above the midpoint of zygomatic arch, which is the weak part of skull, and the anterior branch of middle meningeal artery passes through the groove near its deep surface.
