Question

A cell which has secreted the matrix of cartilage and become embedded in it :

• A. Osteoclast
• B. Osteoblast
• C. Osteon
• D. Chondrocyte

Answer 1

The correct option is D Chondrocyte

Chondrocytes, or chondrocytes in lacunae, are cells found in cartilage connective tissue. They are the only cells located in cartilage, they produce and maintain the cartilage matrix.
Osteoclast are large cells that dissolve the bone. They come from the bone marrow and are related to white blood cells. They are formed from two or more cells that fuse together, so the osteoclasts usually have more than one nucleus. They are found on the surface of the bone mineral next to the dissolving bone.
Osteoblasts are the cells that form new bone. They also come from the bone marrow and are related to structural cells. They have only one nucleus. Osteoblasts work in teams to build bone. They produce new bone called "osteoid" which is made of bone collagen and other protein. Then they control calcium and mineral deposition. They are found on the surface of the new bone
