The internal structure of bone is maintained by remodeling, a three-phase process in which existing bone is resorbed and new bone is laid down to replace it. Remodeling is done by clusters of bone cells called:
A) precursor stimulating cells.
B) osteoclastic cutting cones.
C) basic multicellular units.
D) Haversian system cells.

Question

Quizplus · Accepted Answer

The clusters of bone cells responsible for bone remodeling are called basic multicellular units (BMUs). They consist of osteoclasts (which resorb old bone) and osteoblasts (which lay down new bone). The other choices (A, B, and D) are not accurate descriptions of bone cells or processes related to bone remodeling.
