Question

Quizplus · Accepted Answer

In endochondral ossification of a long bone, the first step is the formation of a bone collar or compact bone around the diaphysis. This provides structural support and serves as a template for future bone growth. Perichondrium is a layer of connective tissue that surrounds cartilage but has no specific role in endochondral ossification. Epiphyseal plate is a cartilaginous region at the end of a long bone, responsible for growth in length. Fibrocartilage is present in intervertebral discs but does not form in endochondral ossification.
