What are the characteristics of sutura vera (true sutures)?

sutures demonstrating interlocking of the adjacent bone surfaces; typically formed by intramembranous ossification

What are the typical examples of the plane suture or harmonia suture?

cruciate suture made up of the intermaxillary, interpalatine, and palatomaxillary sutures

What are the examples of the schindylesis type of suture?

sphenoid-ethmoid-vomer articulation, the palatine-maxilla-vomer articulation

What is the diamond shaped remnant of developing membrane bone at the intersection of the frontal bone with both parietal bones?

the anterior fontanelle

17

What is the posterior fontanelle?

the diamond shaped remnant of developing membrane bone at the intersection of the occipital bone with both parietal bones
