Bone is constantly being constructed and demolished. During resorption, cells known as osteoclasts break down bone, releasing calcium into the bloodstream. The trenches that are left behind are then filled in by construction cells known as osteoblasts. The osteoblasts release collagen into these troughs and eventually evolve into structural bone cells, or osteocytes. Once these osteocytes mix together with calcium, phosphate, and other minerals to form a cement-like substance known as hydroxyapatite, the process of replacing the lost bone is complete.

How should I remove a helmet without further injuring an athlete?
To remove the helmet, one person reaches into the helmet from the bottom to hold the player’s head and neck. At the same time, a second rescuer unsnaps the jaw pads on either side of the helmet. This person then pulls out on the sides of the helmet and carefully slides it back off the player’s head.

Why does it tingle when I hit my funny bone or the inside of my elbow?
When nerves are damaged or irritated, they cause a tingling sensation along the distribution of the nerve, or the path that the nerve follows. Since the funny bone (or ulnar nerve), is very superficial at the elbow, it's very common to irritate it.
