There are many sutures of the skull, which are where skull bones meet. In general, sutures don't fuse until brain growth is complete, therefore allowing the skull to increase in size with the developing brain.
Sutures are fibrous joints with the periosteum externally and outer layer of dura mater being continuous over and under them. They typically appear wavy for added strength.
Named sutures divided by their general location include:
- frontozygomatic suture
- frontomaxillary suture
- frontolacrimal suture
- temporozygomatic suture
- zygomaticomaxillary suture
- parietotemporal suture (parietomastoid suture)
- occipitotemporal suture (occipitomastoid suture)
- sphenofrontal suture
- sphenozygomatic suture
- lacrimomaxillary suture
- nasomaxillary suture
- basal / internal
Specific names are given to where sutures meet, see: skull landmarks
