Osteocytes

​is a type of bone cell that breaks down bone tissue. This function is critical in the maintenance, repair, and remodeling of bones of the vertebral skeleton

The pointer is pointing to three osteoblasts in developing bone. (magnification 400×).​

​

Osteoblasts are the cells required for bone synthesis and mineralization, both during the initial formation of bone and during bone remodeling.

​

​

What is the purpose of osteoblasts?

​Osteoblasts

​

Bad Bruise​

Acts as a bridge ​across the fracture during the repair.

Spongy Bones​ are a lattice of trabeculae (little beams) that are found along lines of stress for perfect resistance from compression.

Compact Bones are arranged in cylinders called osteons. ​Osteons are are arranged in concentric circles called lamellae.

Bone Remodeling

These processes also control the reshaping or replacement of bone following injuries like fractures but also micro-damage, which occurs during normal activity. Wikipedia

​Micro-damage

1. Is a lifelong process

2. Involves mature bone tissue

3. Bone tissue is removed from the skeleton

4. New bone tissue is formed. ​
