Which term means bone end on the diaphysis?

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

Answer: (C)

The main idea here is naming the parts of a long bone. The end parts of a long bone are called epiphyses, while the shaft is the diaphysis. The region between the epiphysis (the end) and the diaphysis (the shaft) is the metaphysis, which includes the growth plate in children. Epiphysis meaning “bone end” fits the question because it specifically identifies the end portion of the bone. The diaphysis is the shaft, not the end, and the metaphysis is the narrow area between the end and the shaft. So the term for the bone end is epiphysis.
