Embryonic skeletal development proceeds through two distinct ossification processes. Intramembranous ossification forms bone directly from mesenchymal connective tissue, while endochondral ossification first builds a cartilage template that is subsequently replaced by bone tissue. Recognizing these two pathways explains why certain bones heal differently and why skeletal disorders selectively affect some bones and not others.
