Question

question 3
a fracture in the shaft of a bone would be a break in the:
a diaphysis
b periosteum
c diarthrosis
d epiphysis

Explanation:

• Diaphysis: The diaphysis is the shaft of a long bone. It is the main, cylindrical part of the bone.
• Periosteum: The periosteum is a membrane that covers the outer surface of all bones (except at the joints of long bones). It is not the bone shaft itself.
• Diarthrosis: A diarthrosis is a type of joint (a freely movable joint), not a part of a bone shaft.
• Epiphysis: The epiphysis is the end part of a long bone, opposite the diaphysis (shaft).

Answer:

A. diaphysis
