Musculoskeletal System

Find out what you didn’t know about your muscles and bones.
  1. Bones can self-destruct: It is possible for your bones to destruct without enough calcium intake.
  2. You are taller in the morning: Throughout the day, the cartilagebetween your bones is compressed, making you about 1 cm shorter by day’s end.
  3. 1/4 of your bones are in your feet: There are 26 bones in each foot, meaning that the 52 bones in account for 25 percent of your body’s 206 bones.
  4. It takes more muscles to frown than to smile: Scientists can’t agree on the exact number, but more muscles are required to frown than to smile.
  5. When you take a step, you are using up to 200 muscles: Walking uses a great deal of musclepower — especially if you take your 10,000 steps.
  6. Your tongue is the strongest muscle in your body: Compared to its size, the tongue is thestrongest muscle. But I doubt you’ll be lifting weights with it.
  7. Bone can be stronger than steel: Once again, this is a pound for pound comparison, since steel is denser and has a higher tensile strength.
