In fetal skull, the sutures are wide and allow slight movement during birth, but later in life they become rigid and fixed. This article will explain the anatomy, structure and function of the sutures of the skull. Key factsTable quiz Anterior aspect of skull Frontonasal suture - between ...
As expected, almost all the sutures in the emu skull progressively close (i.e., they get narrower) and then obliterate during ontogeny. However, in the American alligator, only two sutures out of 36 obliterate completely and they do so during embryonic development. Surprisingly, as maturity ...
The three types of fibrous joints aresutures, gomphoses, and syndesmoses. A suture is the narrow synarthrotic joint that unites most bones of the skull. At a gomphosis, the root of a tooth is anchored across a narrow gap by periodontal ligaments to the walls of its socket in the bony...

As the skull develops, the tissue of the coronal and sagittal sutures (serrated sutures) assumes a specific structure which in part is practically identical to that of a gomphosis joint and may therefore be regarded as a 'multigomphosis'. The nature of this structure justifies the assumption ...

Interpretation of plain radiographs is often challenging due to the low density of the skull in a neonate. Partial suture closure is especially difficult to appreciate. Clinicians are also interested in additional information about brain and CSF-space morphology that could be provided by CT. Probably...
The processes of sutures and synchondroses formation, interdigitation and closure set the normal skull growth. Sutures and synchondroses represent growth sites in normal skull development. These articulations have distinctive characteristics due to their different embryological origins and histologies; ...
