Question

Quizplus · Accepted Answer

During endochondral ossification, bones initially develop as a cartilage model that was formed from mesenchyme, which is a type of embryonic connective tissue that gives rise to various cell types, including those that form cartilage and bone. The periosteum and endosteum are not involved in the formation of the cartilage model, while the perichondrium is a connective tissue layer that surrounds the cartilage but does not form the cartilage itself. Mucous connective tissue is not directly involved in bone development.
