question 4
in the structure of a long bone, which of the following is composed of spongy bone?
articular cartilage
periosteum
all of these
diaphysis

Explanation:

Articular cartilage is smooth connective tissue covering bone ends, not spongy bone. The periosteum is a fibrous membrane wrapping outer bones, not bone tissue. The diaphysis is the long shaft of a long bone, made of compact bone, not spongy bone. None of the listed options correctly identify a structure made of spongy bone (the correct structure would be the epiphyses, which is not an option here).

Answer:

None of the provided options are correct. Note: The epiphyses of long bones are composed of spongy bone, but this is not listed. The given options:

• Articular Cartilage: Not spongy bone
• Periosteum: Not spongy bone
• All of these: Incorrect
• Diaphysis: Made of compact bone, not spongy bone
