1.Sagittal suture, the bone suture from between the eyebrows along the cranial vault to the tip of the herringbone, the deep side of which is the superior sagittal sinus. 2.Human suture, from the posterior 1/3 of the sagittal suture at the tip of the herringbone towards the base of the mastoid process on both sides, and the bone suture between the parietal bone and the occipital bone. 3.Cranial baseline, the baseline of the skull base, i.e., Reid, base, line, is the line from the inferior orbital rim to the external occipital ridge via the superior edge of the external auditory canal. 4.Coronal suture, boundary between the parietal bone and frontal bone, from the coronal sagittal point to the bone suture of the wing point on both sides. 5.Frontal suture, the first 1/3 of the sagittal suture, bounded between the frontal bones on both sides, often closes at the age of 2 years. 6.Temporal scales suture, the bone suture between the temporal bone, frontal bone and parietal bone, starting from the wing point and ending at the star point. 7.Occipital suture, the suture between the occipital bone and the posterior edge of the mastoid process, which is an extension of the herringbone suture to the occipital bone. 8.Parietal mammary suture, the suture between the parietal bone and the base of the mastoid process, which is the extension of the herringbone suture to the parietal bone. 9.Nasal frontal point, the central depression of the nasal root, equivalent to the connection between the frontal bone nasal prominence and the nasal bone. 10.Brow, between, is located about 1.5cm above the nasal frontal point, between the two eyebrows. 11.Brow, arch, is the ridge of the frontal bone 1.5cm above the supraorbital margin, and contains the frontal sinus on the deep side of the inner section of the brow arch on both sides. 12.Frontal nodule, about 5cm above the brow arch, the deep side of the frontal nodule is facing the frontal middle gyrus. 13.Frontal vertex, the intersection of coronal and sagittal suture, also known as coronal sagittal point, is in the junction of the frontal point of the nose to the sagittal line of the external occipital ridge, the middle 1/3 of the junction, the newborn is fontanelle, about 13cm above the eyebrow. 14.Parietal node, the ridge of the parietal bone, is 6cm above the auricle, its deep side is the edge of the superior gyrus; 2cm below it is suitable for the end of the hind limb of the lateral sulcus of the brain. 15.Extraoccipital ridge, located above the craniocervical junction, is a bony elevation in the center of the occipital scales, with the collateral ligament attached, and the deep surface of the ridge is the sinus sink. 16.Parietal occipital point, the intersection of sagittal suture and herringbone suture, also known as herringbone tip, posterior fontanelle in newborns, about 6cm above the external occipital ridge. 17.Supra-occipital line, the semi-arc-shaped bone ridge which is convex to the lateral side from the external occipital ridge to the mastoid process, is the attachment point of sternocleidomastoid muscle and rhomboid muscle, and its deep surface is the upper boundary of the transverse sinus. 18, frontal zygomatic process, frontal bone to the outer edge of the orbital protrusion and the orbital process of the zygomatic bone connected to the angle, also known as the lateral horn protrusion.
