  2. Impact • The first stage is the impact when the bone absorbs enough energy for the bone to break. • Your body deals with this by releasing endorphins.

  4. Boo-boo • Large hematoma or bruise forms around the fracture site. Image from: http://www.bonefixator.com/bone_fracture/fractures_and_healing_1.html

  5. The Calvary is Here! • Specialized cells, called osteoblast begin making new bone. Image from: http://www.bonefixator.com/bone_fracture/fractures_and_healing_1.html

  6. Ossification • This matrix of new bone and hematoma begins to harden. This makes the bone strong again and the break is considered healed. Image from: http://www.bonefixator.com/bone_fracture/fractures_and_healing_1.html

  7. Clean up, aisle 5! • Another specialized cell, called an osteoclast, begins cleaning up any unwanted bone and as well as the hematoma. Image from: http://www.bonefixator.com/bone_fracture/fractures_and_healing_1.html
