limbous

There are two types of squamous sutures: limbous sutures have mutual ridges or serrations, and the more common plane sutures, which exhibit less structured surfaces which are mutually roughened, such as the temporoparietal suture, the suture between the two maxillae, or the meeting of the zygomatic and palatine bones.
