Question

A boy met with a severe accident and there was a fracture in the shaft of a long bone. What do you think is the possible reason for this?

• A. Break in the epiphysis
• B. Break in the metaphysis
• C. Break in the diaphysis
• D. Break in the mesenchyma

Answer 1

The correct option is C Break in the diaphysis

Diaphysis is the middle portion in the shaft of the long bone in humans. The long bone is hollow and has bone marrow and adipose material. Diaphysis is only present in long bones. Hence when the boy met with a severe accident and there was a fracture in the shaft of a long bone there was a break in the diaphysis. Thus the correct answer is option C.
