** Growth-Repair **
**Your skeleton grows in different ways, gets injured in different ways, and repairs itself in different ways.**

**Growth**
**Bones have cells and tissues, such as blood and nerves.** **Because your bone cells are alive. They form new bone tissue as you grow.** **Even after you are grown, bone tissue continues to form within your bones. For example, every time you play basketball or football, your bones absorb the force of your weight. When that happens new bone tissue is made.** =**Repair**= **Sometimes when you break a bone new bone tissue forms. Bone tissue fills in gap between the end of the bone and at the end of the other bone. The healed part of the new bone may be stronger than the original bone.**

=**Injury**= **Here are some way bones can be injured:** **#1 Break: This happens when you fall and all of your weight is on a few bones.** **#2 Sprain: This is when a ligament tears. It's a common joint injury.** **#3 Dislocation: This is when a bone comes out of it's joint, like in your arm ball and socket joint. If the ball part comes out of the socket, the arm is dislocated.**
