Cranial Motion

The different cranial sutures have the anatomical forms of the movement they must develop.
For our purpose, the most useful examples of joint surfaces are of two kinds:
-the first ones, called hereby "bite" surfaces, correspond to teethlike projections
-the second ones, "bevelled", correspond to parietal-temporal joints

Bite and bevelled sutures are connected by fibrous tissues that allow slight movements (in micron units) and its direction depends on related bone surfaces that permit movements of bearing, sliding or hinge.

General classification depending on movements is:

-Flexion extension - Occiput - Sphenoid- Ethmoid and Vomer.
-External and internal rotation -Temporal-Frontal - Maxillary bone - Palatin - Parietal - Lacrimal bone and Nasal bone.
