Endochondral Ossification

The video explains endochondral ossification, a process of bone formation occurring in utero for bones beneath the skull, except the clavicle. It highlights the role of hyaline cartilage, chondrocytes, and osteoblasts in forming the bone collar and marrow cavity. The primary ossification center forms in the diaphysis, while the secondary ossification center develops post-birth in the epiphyses. The video also discusses the implications of articular cartilage degradation, leading to osteoarthritis.
