Q. 30 - Biology

Question

What are the roles of osteoblasts, osteocytes, and osteoclasts? 

Step-by-Step Solution

Answer

• Osteocytes carry out the blood's role of exchanging nutrients and wastes. They also keep the mineral salts in the bony matrix recycled, which helps to maintain proper bone structure. 
• Osteoclasts break down the skeletal matrix by releasing lysosomal enzymes and acids, which destroy bone tissue. 
• Bone cells called osteoblasts are in charge of producing new bone.

Step 1 : Introduction

Osteocytes are the cells that form the bones themselves, while osteoblasts are in charge of the formation of new osteocytes and osteoclasts are in charge of the resorption of old bone matter. Thus, the three types of bone cells work together to regulate bone formation, sustenance, and decay. 

Step 2: Overview of osteoblasts, osteocytes, and osteoclasts

• Osteoblasts can synthesize and secrete bone matrix and take part in the mineralization of bone. 
• An osteoclast is a functional unit that destroys and absorbs bone to provide room for the growth of new bone and the preservation of bone density.
• osteocyte, a type of cell found in the bone's mineralized tissue. It is contained in a tiny chamber referred to as a lacuna.
