The Skeletal System

It's Going Tibia Okay

P.S. In the joke a tibia is a bone in the leg...

What Does The Skeletal System Do?

The skeletal system keeps you up and running. It prevents everyone from being like jello. The skeletal system has 3 extremely important jobs: to protect organs, produce bone cells, in bone marrow, and let humans move around. Bones also tire out. Diseases unfortunately spread. Why? How?

Major Body Parts... What Do They Do?

  • The Spine (protects spinal cord and nerves)
  • The Skull (protects brain)
  • Shoulders/Knees (allows us to move, grab)
  • Hands/Feet (allows us to do more)
  • Ribs (protects the heart and lungs)

Bone fit together like a puzzle, if one is gone the rest goes tumbling down.

What are the jobs of the skeletal system?

The system holds everything together, and without bones, people would be blobs, rolling around. Bones do in fact grow to our size, and that is why kids might get an occasional pain in their legs, arms, or muscles. When a baby is first born they have around 300 bones, but by the time they reach adulthood, they have only 206. Some bones fuse together, to become one. In order to keep your bones together, ligements connect bone-to-bone. Whereas, tendons connect muscle-to-bone. These are just a few of the jobs of the skeletal system.

How Can You Keep Your Bones Healthy?

In order to keep our bodies healthy, we should follow these simple steps.

  1. Get enough calcium
  2. Don't put too much pressure on our bones (they may break)
  3. Use our bones daily
  4. Exercise 1 hour a day
  5. Eat more fish (tuna, salmon, sardines) or green vegetables (kale, okra, Chinese cabbage, broccoli)
  6. Be careful with our bodies
  7. REMEMBER: Bones are alive!


What are common diseases or problems that may occur?

A common problem that happens is a broken bone. In the U.S.A., 6 million people break a bone in 1 year. Bones may break because they are weak, Osteoporosis is in the bone, or apply too much pressure on the bone(s). Osgood-Schlatter Disease is knee pain, and the bones in the knee are wearing down. Parkinson's Disease is when we lose the ability to move. Muhammad Ali had Parkinson's Disease. Next, Arthritis affects joints. Bone Cancer can eat away at the bone. Another common problem is sprains, especisally in the ankle. It's where the ligements and/or tendonds rip. A few diseases are told, but there are several more.

Osteoporosis. What is it? What puts you at risk?

With more than 53 million Americans at risk for Osteoporosis, doctors are rushing to find a cure. Osteoporosis is when our bone mass gets low (bone thinning). The only problem is that if your bone thins, how do you build the bone back up? There are currently drugs that will slow down the bone thinning, but will not fully stop the thinning. There are so many risks of getting Osteoporosis. If you are a woman you have a 1 in 3 chance. Men have a 1 in 5 chance. If you are European, American, or Asian, you have a higher risk. Osteoporosis usually runs in families. You cannot tell if you have it in any way other than getting a Bone Mineral Density test. Osteoporosis is called "The Silent Disease" because of this.

What Are the Stages of osteoporosis

Here are the stages of Osteoporosis:

  1. Bone Pain
  2. Bone Thinning
  3. Bone Loss

These stages are unpleasant, but doctors can replace bones that are too thin to hold you. Unfortunately, there is still no cure.

Broken Bones

The most common broken bone in children is the shoulder bone. In adults, it is the clavicle. Bones are extremely strong, but when too much pressure is applied, they might snap. What should you do?

These are the steps you should take:

  • Immobilize Limb
  • Apply Ice
  • Elevate Limb
  • Give Pain Relief
  • Seek Medical Help ASAP

You could also follow the RICE rule:





All of these strategies will help you to provide the best possible care.

What Do Bones Do For Others?

In simple words, bones do not just have one purpose, but many. After you die your bones have a job: to let the future know what we were like. Currently, though, when you're still alive, your bones do more for others than for you. The give people jobs. There are doctors, nurses, and surgeons who work with bones. Not only do they do that, but they allow you to be kind towards others. So today, say thank you to your bones and doctors. Say thank you to the cast you had in 5th grade. Bones keep you up and running- literally. Be careful in the with your bones, you only get one set.

Fun Facts

  • Bones are made of calcium, cells, minerals!
  • Your bones are split into two categories: Axial (holds you up straight) and Appendicular (helps you to move)!
  • There are specific doctors for different bones!
  • There are 2 types of broken bones, Fractures (small cracks) and Complete Fractures (bone in 2 pieces)!
  • Your femur (thigh bone) is the longest bone!
  • A bone in your ear measures only 0.11 inches!
  • The funny bone is actually the humorous (humor)!
  • Some joints don't move at all, like the cranium
