What is the term for the end of a long bone?

• A. Diaphysis
• B. Periosteum
• C. Epiphysis
• D. Endosteum

Answer: (C)

The term for the end of a long bone is epiphysis. This part of the bone plays a crucial role in joint movement and stability, as it articulates with adjacent bones at the joints. The epiphysis is typically covered with articular cartilage, which helps reduce friction and absorb shock during movements. Additionally, the epiphysis contains spongy bone that is often filled with marrow, aiding in the production of blood cells. The other terms in the choices refer to different structures associated with bones. The diaphysis is the long, tubular shaft of a bone that provides strength and support. The periosteum is a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints, serving as a point of attachment for muscles and ligaments, as well as containing blood vessels and nerves. The endosteum is a thin membrane lining the inner surface of the bone, particularly the medullary cavity, which plays a role in bone growth and repair. Understanding these distinct structures is essential for comprehending bone anatomy and function.
