Which bone (yellow) is centrally located and joins with most of the other bones of the skull?
The yellow centrally located bone is the sphenoid bone, a type of irregular bone whose function is the provision of support to the facial muscles.
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 by which the bones of the body are formed are intramembranous and endochondral ossification.
The simpler method of the two is intramembranous ossification; this forms bone directly within the mesenchyme from the fibrous membrane. Bones formed through this method are the skull's flat bones, mandible, and the clavicle's medial part.
Endochondral ossification, on the other hand, forms bones within the hyaline cartilage developed from the mesenchyme. Cartilage replacement by bone also occurs in endochondral ossification. This process forms most bones in the body.
