Which of the following cells are large and multinucleated cells of bone?
a) chondrocytes
b) osteoclasts
c) oesteocytes
d) osteoblasts
Which of the following cells remove bone tissue by removing its mineralized matrix and breaking up the organic bone?
a) chondrocytes
b) osteoclasts
c) oesteocytes
d) osteoblasts
Explanation: Osteoclasts are the cells that degrade bone to initiate normal bone remodeling and mediate bone loss in pathologic conditions by increasing their resorptive activity.
The process in which osteoclasts remove bone tissue by removing its mineralized matrix and breaking up the organic bone?
a) bone breaking
b) bone fracture
c) bone resorption
d) bone restoration
Explanation: Bone resorption is resorption of bone tissue, that is, the process by which osteoclasts break down the tissue in bones and release the minerals
Which of the following cells are equipped with phagocytic-like mechanisms similar to circulating macrophages?
a) chondrocytes
b) osteoclasts
c) oesteocytes
d) osteoblasts
Bone is a dynamic tissue. Which of the following cells reshaped it?
a) osteoclasts
b) osteoblasts
c) oesteocytes
d) both a and b
30 % of bone matrix composed of organic material, chiefly………
a) glycoprotein
b) fibrous protein
c) collagen
d) calcium
Explanation: Collagen is a protein found in connective tissue, skin, tendon, bone, and cartilage. It provides structural support to tissues
