During Endochondral Ossification the Perichondrium Becomes the?

Endochondral Ossification
The perichondrium becomes the periosteum, which contains a layer of undifferentiated cells (osteoprogenitor cells) that later become osteoblasts. These osteoblasts secrete osteoid against the shaft of the cartilage model that serves as support for the new bone.

What occurs during endochondral ossification?

During endochondral ossification, an avascular tissue (cartilage) is gradually converted into one of the most highly vascularized tissues in the vertebrate body (bone). This conversion is dependent upon an angiogenic switch along the growth plate.

Does the Perichondrium become periosteum?

Periosteum and perichondrium grafts are biomembranes with two layers, an outer fibrous layer and an inner cambium, or osteogenic, layer. Perichondrium lines developing bone, and when vascularized, becomes periosteum, or the nonjoint lining of bone.
