Question

multiple choice 2 points

expanded ends of a long bone are called the

articular cartilages
diaphyses
eriosteums
iphyses
osteums

Explanation:

Identify the question and key anatomical terms

The question asks for the term that describes the expanded ends of a long bone. We need to evaluate the anatomical structures of a long bone using our knowledge of Bone Histology and skeletal anatomy.

Analyze the given options

• articular cartilages: This is the thin layer of hyaline cartilage covering the joint surfaces, not the bone ends themselves.
• diaphyses: The diaphysis refers to the elongated shaft of a long bone.
• periosteums: The periosteum is the fibrous membrane covering the outer surface of the bone.
• epiphyses: The epiphyses (plural of epiphysis) are the expanded proximal and distal ends of a long bone.
• osteums: This is not a standard anatomical term for a bone region (though endosteum covers internal surfaces).

Determine the correct anatomical term

The expanded ends of a long bone are anatomically defined as the epiphyses.

Answer:

• articular cartilages
• diaphyses
• periosteums</mcq-correct>
• epiphyses (Correct answer)
