Question

Formation of cartilaginous bones involves __________________.

• A. Deposition of bony matter by osteoblasts and resorption by chondroclasts
• B. Deposition of bony matter by osteoclasts and resorption by chondroblasts
• C. Deposition of bondy matter by osteoclasts only
• D. Deposition of bony matter by osteoblasts only

Answer 1

The correct option is A Deposition of bony matter by osteoblasts and resorption by chondroclasts

A. Deposition of bony matter by osteoblasts and resorption by chondroclasts.

EXPLANATION: Ossification is the process of the formation of cartilaginous bone. It begins about the third month of fetal life in humans. Chondroclasts are cartilage forming cells. In ossification process bones are resorbed by chondroclasts and is deposited by osteoblasts, which are bone forming cells. During childhood, bone formation process exceeds resorption, but as the aging process occurs, resorption exceeds formation.
