Verified step by step guidance

Step 1: Begin by understanding the structure of a long bone. A long bone typically consists of three main regions: the epiphysis (ends of the bone), the metaphysis (narrow region between the epiphysis and diaphysis), and the diaphysis (shaft or central part of the bone).

Step 2: Recall the definition of the diaphysis. The diaphysis is the elongated, cylindrical shaft of a long bone that provides structural support and is primarily composed of compact bone surrounding a central medullary cavity.

Step 3: Compare the anatomical terms provided in the question: Metaphysis refers to the transitional region between the epiphysis and diaphysis, Epiphysis refers to the rounded ends of the bone, and Periosteum refers to the outer fibrous layer covering the bone. None of these terms describe the shaft of the bone.

Step 4: Confirm that the term 'diaphysis' matches the description of the shaft or central part of a long bone in the arm, as it is the correct anatomical term for this region.

Step 5: Conclude that the correct answer is 'Diaphysis,' based on the definitions and anatomical structure of a long bone.
