Title Of Article: How Do Broken Bones Heal?
Publication: Discovery Health 2011
Author: Robert Lamb

Summary:

The article I chose to discuss describes the process of how bones repair themselves. In brief, this article goes over the function of bones and what they use red and yellow marrow for. It also talks about how there are three different types of cells responsible for bone growth, and how there are four phases during the process of bones healing themselves. This article provides the details of how bones really heal themselves within the body, and all the different terms for each process.

Discussion:

I will discuss the details the article provides for each function and process the bone goes through. The main function of bones is to create structure for the body but also the body stores minerals in the compact bone. The red marrow is also used to produce red blood cells and the yellow marrow is used to store fat. Your bones never stop growing or changing, and the three primary cells used in the bone growth process are osteoclasts, osteoblasts, and chondroblasts. When a bone is first broken the body almost immediately starts the healing process, which has three different stages. The first stage is when the bone is broken so are the blood vessels, so then the blood clots and creates a fracture hematoma. This keeps the bone pieces in line so it mends back together correctly. The second stage is the fracture hematoma is eventually transformed into a soft callus with help from the bone growth cells. The chondroblast turns the soft callus into fibrocartilaginous callus which creates a stronger bond to connect the bones. The third stage is when the osteoblasts move in and turn it into bone callus which last a few weeks and then eventually turns into hard compact bone.
