True or False: The ends of long bones are called epiphyses.

The statement that the ends of long bones are called epiphyses is accurate. In the anatomy of long bones, the term "epiphysis" refers specifically to the rounded ends of the bone that are typically covered in articular cartilage and involved in joint formation. These epiphyses are crucial for facilitating movement at joints and serve as growth regions in growing bones, where they are separated from the main shaft (diaphysis) by the growth plate (epiphyseal plate) in adolescents.

As the individual matures, the epiphysis becomes fused to the diaphysis when growth in length ceases, marking a significant phase in skeletal development. This definition aligns correctly with established anatomical terminology, confirming the truth of the statement. Thus, the understanding of long bone structure underscores the functional significance of the epiphyses in both maturation and locomotion.
