Question

question 47

the expanded ends of a long bone are called the ______.

a epiphyses
b diaphyses
c articular cartilages
d periosteums
e endosteums

Explanation:

Identify the anatomical region described

The question asks for the term that describes the "expanded ends of a long bone."

Analyze the structural options

• epiphyses: These are the expanded proximal and distal ends of a long bone, typically composed of spongy bone covered by a thin layer of compact bone.
• diaphyses: This refers to the tubular shaft that runs between the proximal and distal ends of the bone, which is a concept related to Diaphysis Structure.
• articular cartilages: This is the thin layer of hyaline cartilage covering the joint surface of the epiphysis.
• periosteums: This is the fibrous membrane covering the outer surface of the bone.
• endosteums: This is the delicate membranous lining of the bone's internal medullary cavity.

Match description to the correct term

The expanded ends are specifically called the epiphyses (singular: epiphysis).

Answer:

• A epiphyses (Correct answer)
• B diaphyses
• C articular cartilages
• D periosteums
• E endosteums
