Cartilage.
The cartilage at the end of a long bone is articular cartilage. The end of the humerus is the humeral head. The entire region of a long bones end is the epiphysis and occurs at both ends.
cartilage
In the epiphysis, or end of the bone, is spongy bone which contains red bone marrow. On the external part of the epiphysis is articular or hyaline cartilage.
because it turns into bone
cartilage is present at the end of a bone at joints as it is soft so the joints bend and help in doing our work properly.bones are hard but a cartilage is soft.
so that the bone doesnt get rubbed with each other!
The articular cartilage is the thin layer of white tissue covering the bone in the joint space. The articular cartilage is made of hyaline cartilage.
cartilage is more flexible than bone making the shark more hydrodynamic.
