I WONDER - What Are The Different Parts Of Bones?

The video tutorial explains the structure of bones, starting with the hard outer layer called the cortex, which is mainly composed of minerals. It then describes the inner portion known as the mendular, made up of spongy tissue called trabecular bone, which is less dense than the cortex. The ends of bones, referred to as epiphysis, and the thin layer surrounding the bone, known as the periosteum, are also discussed. Finally, the video covers the articulation, which is the point where two bones meet to form a joint.
