Verified step by step guidance

Step 1: Understand the anatomy of a long bone. A long bone consists of three main regions: the ends, the middle shaft, and the outer covering. The ends are called epiphyses, the middle shaft is called the diaphysis, and the outer covering is the periosteum.
Step 2: Review the definitions of the terms provided in the options. For example, 'epiphyses' refers to the rounded ends of the bone, 'diaphysis' refers to the shaft or central part of the bone, 'metaphyses' are the regions between the epiphyses and diaphysis, and 'periosteum' is the outer fibrous layer covering the bone.
Step 3: Match the correct anatomical terms to the question. The ends of the long bone correspond to 'epiphyses,' and the middle shaft corresponds to 'diaphysis.'
Step 4: Eliminate incorrect options based on the definitions. For example, 'periosteum' is not part of the internal structure of the bone, and 'metaphyses' are transitional regions, not the ends or middle.
Step 5: Select the correct answer based on the matching terms: 'epiphyses; diaphysis.'
