The skeletal system is made up of various cells that work together to maintain bone health and support bodily functions. The three key cells in the skeletal system are osteoblasts, osteocytes, and osteoclasts.

Osteoblasts are bone-forming cells. They are responsible for producing the bone matrix and promoting mineralization, which strengthens the bone. Osteoblasts secrete collagen and other organic materials that provide the framework for bone tissue. They also facilitate the deposition of calcium phosphate, which hardens the bone.
Osteocytes are mature bone cells that are derived from osteoblasts. They become embedded in the bone matrix and are responsible for maintaining the bone tissue. Osteocytes play a crucial role in the communication and maintenance of bone homeostasis by sensing mechanical stress and relaying signals to osteoblasts and osteoclasts to initiate bone remodeling when necessary.
Osteoclasts are large cells responsible for the resorption of bone tissue. They break down the bone matrix by secreting acids and enzymes, a process essential for bone remodeling, healing, and the release of calcium into the bloodstream.

Bone Repair Steps:

Bone repair occurs in four main stages:

Hemostasis: Immediately after a bone fractures, blood vessels are damaged, leading to bleeding. Platelets gather at the site, and a clot forms to stop the bleeding. This clot, known as a hematoma, helps stabilize the fracture.
Inflammation: During this phase, immune cells clear away debris and bacteria, while osteoblasts and other cells begin the repair process. The area becomes swollen, and there may be pain and redness.
Bone Formation: In this phase, soft callus forms, made of cartilage, which gradually transforms into a hard callus of bone. This new bone formation bridges the gap between the broken bone ends.
Remodeling: The final phase involves the bone remodeling process, where the hard callus is reshaped into the bone’s original structure by osteoclasts and…
