Clusters of which type of bone cells are responsible for bone remodeling?
a. Trabeculae
b. Osteoclastic cutting cones
c. Basic multicellular units
d. Haversian system cells
ANS: C
Remodeling is carried out by clusters of bone cells termed basic multicellular units. The basic multicellular units are made up of bone precursor cells that differentiate into osteoclasts and os-teoblasts. Trabeculae are plates found in spongy bone. The osteoclasts form a "cutting cone," which gradually resorbs bone, not remodels it. Haversian canals are part of compact bone.
