Question

question 47
which of the following is correctly matched?
a osteocytes - function in bone remodeling
b endosteum - lines central canal of the osteon
c osteoclasts - responsible for reabsorption
d periosteum - lines the medullary cavity
e osteoblasts - break down bone tissue

Explanation:

• Osteocytes are mature bone cells that maintain bone tissue, not directly function in bone remodeling.
• The endosteum lines the central canal of the osteon.
• Osteoclasts are responsible for bone resorption (reabsorption).
• The periosteum covers the outer surface of bones, not lines the medullary cavity.
• Osteoblasts build bone tissue, not break it down.

Answer:

B. endosteum - lines central canal of the osteon, C. osteoclasts - responsible for reabsorption
