Question

which of the following cell types is primarily responsible for breaking down osseous (bone) matrix?
a.) osteocyte
b.) osteoclast
c.) osteogenic cells
d.) osteoblast

Explanation:

Osteoclasts are large multinucleated cells that secrete enzymes and acids to break down the bone matrix (osteolysis). Osteocytes are mature bone cells that maintain bone tissue. Osteogenic cells are stem - like cells that can differentiate into osteoblasts. Osteoblasts are responsible for bone formation by secreting the organic components of the bone matrix.

Answer:

B. Osteoclast
