Which term describes a bony expansion on the end of a bone carried on a narrow neck?

• A. Head
• B. Tuberosity
• C. Tubercle
• D. Epicondyle

Answer: (A)

The head. This term describes the rounded end of a long bone that sits at the end and is connected to the shaft by a narrow neck, forming a joint surface with another bone. The head is the part that articulates with the adjacent bone and is typically capped with articular cartilage. In contrast, tuberosities and tubercles are bumps for muscle or tendon attachment, with tuberosities being larger and tubercles smaller, and epicondyles are projections above a condyle near the end of the bone.
