Which of the Following are Called Bone-Building Cells and Secrete

Question

Which of the following are called bone-building cells and secrete the components of the matrix?
A) Red marrow
B) Osteoblasts
C) Osteocytes
D) Osteoclasts
E) Yellow marrow

Accepted Answer

Osteoblasts are responsible for secreting the components of bone matrix and are therefore called bone-building cells. Red and yellow marrow are not bone cells, osteocytes are found within the bone matrix but do not secrete components of it, and osteoclasts break down bone rather than building it up.
