Fill in the Blanks

White double-layered membrane covering the external surface of the entire bone except the joint surfaces.

The inner layer of the periosteum contains

Let's talk about bone development

Membranous is going to be our key word here.
So bone will develop from fibrous membrane

​Intramembranous ossification

Remember chondro= cartilage.
So this will be bone development by replacing hyaline cartilage.

​Endochondral ossification

Formation of the Bony Skeleton

Multiple Choice

Endochondral ossification forms all bones in the body except

• clavicles

• phalanges

• humerus

• femur
