Question: 1 / 400

What is the primary function of osteocytes?

To produce blood cells

To maintain bone tissue

The primary function of osteocytes is to maintain bone tissue. Osteocytes are specialized bone cells that originate from osteoblasts, which are responsible for bone formation. Once osteoblasts have encased themselves in the bone matrix they created, they differentiate into osteocytes. These mature bone cells play a crucial role in monitoring and maintaining the bone's microenvironment. They help regulate the balance of bone formation and resorption, responding to mechanical stress by communicating with other bone cells through their long, hair-like processes called dendritic processes. This cellular communication helps to adapt bone density and structure to the mechanical loads placed on the skeleton, ensuring its strength and integrity. This vital role in maintaining bone health distinguishes osteocytes from other cell types such as those involved in blood cell production, muscle contraction, or nutrient transport.
