There are many interesting facts about the bones but these are a few that I find very interesting and I hope that you do too.
Bones in numbers
- The adult human has 206 bones in the body.
- The area with the most bones is the hand and wrist which contains 27 bones. The foot comes a close second with 26 bones.
- Humans have seven cervical (neck) bones, this is the same number as that of a giraffe. The dinosaur diplodocus had 15 cervical bones.
- In the spine, the most joints at individual segments is in the thoracic spine (mid back). The vertebra here have ten joints, this increase is predominantly due to two ribs attachments on each side.
- Bone is remarkably strong, pound for pound bone is stronger than steel. A cubic inch of bone, in theory, can take a load of greater than 8600kg. This is just a little less than a monster truck.
- The smallest bone in the body is the stapes in the inner ear and is about the size of the ‘1’ on a one pence coin. The vibration of this is controlled by the smallest muscle in the body the stapedius.
- The most commonly broken bone in an adult is the arm which makes up about 50% of broken bones. In children it is the collar bone.
Miscellaneous bone facts
- The bone in the thigh (the femur) is not only the longest bone in the skeleton it is also the heaviest and strongest.
- There is only one bone in the body that is not connected to another and that is the hyoid bone. This is a horseshoe shaped bone at the base of the tongue. This aids in tongue movement and swallowing.
- Tendons connect bone to muscle and ligaments connect bone to bone. Ligaments are present predominantly around the joints to provide stability.
- As well as allowing movement and protecting the organs and spinal cord the bones also produce red and white blood cells.
- Cartilage is a fibrous tissue that covers the bone surface and keeps bones from rubbing together.
- The most mobile joints in the body are the ball and sockets joints which are the shoulders and hips. This allows movement in many different directions.
