Which of the following is NOT a type of specialized cell contained in the bone?
Correct Answer
B. Osteoflast
Explanation
Bone tissue contains three kinds of specialized cells: (1) osteoblasts, (2) osteocytes, and (3) osteoclasts. Osteoblasts form bone matrix by laying down collagen fibers and other proteins and depositing hard mineral material. Osteocytes are osteoblasts that have become trapped in the bone matrix they manufactured and live embedded there for years. Osteocytes help to control the mineral balance of the body and also respond to the stresses created by physical activity. Osteoclasts erode the matrix during normal bone turnover, during growth, and during the healing of fractures.
