Bone collar
Bone Collar
The Bone Collar (pronunciation: /boʊn kɒlər/) is a crucial component in the process of bone formation or ossification.
Etymology
The term "Bone Collar" is derived from the Latin words 'os' meaning bone and 'collum' meaning neck or collar.
Definition
A Bone Collar is a compact layer of bone that forms around the shaft of cartilage models during endochondral ossification. It is the first sign of bone formation in the developing fetus and plays a significant role in the development and growth of long bones.
Function
The Bone Collar serves as a support structure for the developing bone. It prevents the underlying cartilage from expanding, thereby directing the growth of the bone lengthwise. It also acts as a barrier, preventing the diffusion of calcium ions from the cartilage into the surrounding tissue, which is crucial for the proper mineralization of the developing bone.
