This is a structure of a long bone that stores energy.
Marrow
This is the region of a long bone that articulates with other bones.
Epiphysis

Diaphysis
This is a layer of hyaline cartilage that reduces friction between bones involved in the joint.
Articular cartilage
This is a layer of hyaline cartilage that allows the Diaphysis to grow in length.
Epiphyseal plate
