=== Broken Bones ===
[[Image:Broken Bone.jpg|right|250px|thumb|An example of broken bone. The radial nerve travels down the arm and supplies movement to the triceps muscle at the back of the upper arm. It also provides extension to the wrist, and helps in movement and sensation of the wrist and hand. The usual causes of nerve dysfunction are direct trauma, prolonged pressure on the nerve, and compression of the nerve from nearby body structures.]]
Your bones are tough stuff - but even tough stuff can break. Like a wooden pencil, bones will bend under strain. Most fractures occur in the upper extremities: the wrist, the forearm, and above the elbow. Also if the pressure is too much, or too sudden, bones can snap. You can break a bone by falling off a skateboard or crashing down from the monkey bars.
