Anatomy of a Long Bone: Structure and Key Components #1347572 (License: Personal Use)

This diagram illustrates a typical long bone, such as the femur or humerus, divided into epiphyses (ends), metaphyses (growth zones), and diaphysis (shaft). Key features include articular cartilage at joint surfaces, spongy bone in the epiphyses, compact bone forming the shaft, the medullary cavity housing marrow, and the endosteum lining internal surfaces. The epiphyseal line marks former growth plate activity.
