  1. [`Your skeleton is made of more than 200 bones:
  2. Inside your body are 206 bones. Each bone plays a very important role in making all the mechanics of your body function properly. If a bone is broken, all the bones around it can’t perform their duty properly.`,
  4. `Bones are filled with a spongy tissue:
  5. Bone marrow is a spongy substance that’s found inside large bones like your hips, pelvis, and femur. Bone marrow houses stem cells. Stem cells are responsible for producing many of your body’s most important cells, including blood, brain, heart, and bone cells.`,
  6. `
  7. Babies are born with 300 bones
  8. Adults will end up with only 206 bones, but babies are born with almost 100 more. It’s not that bones disappear as we grow older. Instead, these tiny bones fuse together to form the larger bones of the skeletal system.
  9. `,
  10. `
  11. The smallest bone in the body is in your ear
  12. The stapes, a bone in your inner ear, is the smallest of all your bones. This bone is also sometimes called the stirrup because of its Y shape. Together with the anvil and hammer bones, the stapes helps translate sounds you hear into waves your brain can understand.
  13. `,
  14. `
  15. The longest bone in the body is in your leg
  16. The femur, which runs from your hip to your knee, is the longest and largest bone in your body. It’s also the strongest. Just think of all the weight that bone handles in a day. No wonder it’s so strong!
  17. `,
  18. `
  19. Bones are designed to take a beating
  20. Yes, bones can break. But they’re designed to stand up to daily wear and tear. For example, some bones must be able to absorb two to three times your body weight in force. They must also be resilient. You take 1 to 3 million steps per year, so bones are built to take the constant use.

  22. `
  23. ore than half your bones are in your hands and feet
  24. You have 206 bones in total, and 106 of them are in your hands and feet.
  25. `,
  26. `
  27. One bone isn’t connected to any other bones
  28. The hyoid bone, which is in your throat, is the only bone that doesn’t connect to a joint. The hyoid is responsible for holding your tongue in place.
  29. `,
  30. `
  31. Most people have 12 ribs, but some have 13
  32. A 13th rib is rare — only 1 percent of people are born with it. In most people, this extra rib, called a cervical rib, can cause medical issues like neck pain. For that reason, people born with this extra rib often have it removed.
  33. `,
  34. `
  35. The biggest joint in your body is your knee
  36. At the knee joint, three bones connect: your femur, tibia, and patella. Those three large bones require an equally large joint to connect them. That’s why your knee is the largest joint in your body.
  37. `,
  38. `
  39. A skeletal system isn’t that common in the world
  40. Humans are part of a group of creatures called vertebrates. That means our bones are covered by a system of tissue and skin. Only 10 percent of the world’s animals (humans included) are vertebrates.
  42. The other 90 percent are invertebrates. Their bones are on the outside of their body.
  43. `,
  44. `
  45. Bones are strong, but teeth are stronger
  46. The enamel on your teeth, which are considered part of your skeletal system, is actually stronger than bones. Enamel protects the delicate nerves and tissue inside your teeth. Inch for inch, your teeth can take more wear and tear than any of your other bones.
  47. `,
  48. `
  49.  Bones are natural healers
  50. When you fracture a bone, your body will go to work producing new bone cells and helping heal the break. A cast or brace just ensures the bone heals straight so you don’t have more problems in the future.
  51. `,
  52. `
  53. You can eat your way to stronger bones
  54. Bones lose strength over time. Keeping them strong requires eating calcium-rich foods like dairy products, broccoli, and some fish. Exercise, especially weight-bearing exercise, helps keep bones strong, too.
  55. The skeletal system can support you for a lifetime of movement. Taking proper care of it ensures you can move longer, experience more, and have greater health. Knowing how to properly care for your bones can go a long way to a healthy, fulfilling life.
  56. `,
  57. `
  58. How to keep your bones healthy
  59. Your bones gain in density until you turn 30. Then density declines unless you get enough exercise, calcium, vitamin A, vitamin K and vitamin D from the foods you eat. What makes healthy bones their healthiest is providing them with the nutrients they need and getting exercise — even daily walks.

  61. `
  62. How broken bones heal
  63. The process can differ based on what kind of break occurred. Most breaks are healable, and blood vessels form in the area almost immediately after you break it to help the healing process begin. Within 21 days, collagen forms to harden and hold the broken pieces in place. The damaged surfaces knit together to form new bone — and often the new bone is stronger than the original one.

  66. Your skeleton has many jobs
  67. It moves you. It protects your brain, heart and lungs. It manufactures blood cells. And it stores and regulates minerals to help your entire system function.
  68. `,
  69. `
  70.  Where you have the most bones
  71. The 54 bones in your hand, fingers and wrists allow you to write, use a smartphone and play piano.
  72. `,
  73. `
  74. Your teeth are part of your skeleton, too
  75. They contain calcium and minerals like bones. But they lack collagen, which gives bones flexibility and strength.
  76. `,
  77. `
  78. Why do joints creak?
  79. Muscles and ligaments support your joints, and cartilage helps to cushion them. When cartilage wears out, arthritis occurs.
  80. `,
  81. `
  82. What’s a funny bone, anyway?
  83. It’s not even a bone. It’s your ulnar nerve, which runs inside your elbow. Hitting it triggers a surprisingly tingling, prickly pain.
