What is being described when you are informed by the orthopedic surgeon that you have broken the middle region of the humerus?
Correct answer
D
Rationale
When the orthopedic surgeon informs you of a break in the middle region of the humerus, they are referring to the shaft or long portion of the bone, which is known as the diaphysis. The epiphysis is the end part of a long bone, while articular cartilage covers the ends of bones in joints. Perichondrium is a layer of connective tissue surrounding cartilage.
