Which bone (yellow) is centrally located and joins with most of the other bones of the skull?

The bone that is centrally located and joints with most of the other bones of the skill is the sphenoid bone. It acts as the bone that hold everything together at the center, meaning that almost all of the other bones fit right into the sphenoid bone.

 

What are the two mechanisms by which the bones of the body are formed, and which bones are formed by each mechanism?

The two mechanisms that allows the bones of the body to be formed are first, intramembranous ossification where bone develops or comes directly from the mesenchymal tissue. The bones produced from intramembranous ossification are the compact and spongy bones, for example, bones found in the cranial area. Next is the endochondral ossification which occurs when a cartilage is replaced by bone. Our long bones and bones found at the base of the skull come from endochondral ossification.
