16. List the five steps of primary endochondral ossification that occur following the first 8 weeks of embryonic development: A bone collar forms around the diaphysis of the hyaline cartilage model Cartilage in the center of the diaphysis calcifies and then develops cavities The periosteal bud invades the internal cavities and spongy bone forms The diaphysis elongates and a medullary cavity forms The epiphyses ossify
