What is Strongest to Weakest Bone in the Human Body, Femur bone is strongest & Middle Ear is weakest
There are 2 types of bone in the human body,
- compact bone and
- spongy bone (often called trabecular bone).
As you can see in this Femur bone is strongest (spanning from the hip to the knee) the compact bone is present in the shaft and of course, it is very compact. However, this compact bone is only very resistant to force/pressure applied if it is applied from above pressing down, or from below pressing up. This is one of the major reasons the femur is able to hold our body weight. On the other hand, if force is applied from the sides it will collapse, like a toothpick, try breaking it from above or below but when you break it from the sides, it buckles.
- Now, soft bone or trabecular bone is obviously less dense as shown in the diagram, there are spaces. But this is very cleverly designed (engineers will understand this as they may have come across it before),
- The way the trabecular bone is designed, is to channel all of the force applied from above inwards and directly to the compact bone.(Strongest to Weakest Bone in the Body)
What is the weakest bone in our body?
Well, I hope you have understood that our bones have ‘strong’ and ‘weak’ components but they all act as strengths of their individual bone anatomy. So it really depends on genes + diet + what position the bone is in our body and where the force is applied.
Small doesn’t mean weak as we could have small but compact bones (like in our feet).
For example,
- The collar bone people have been banging on about, The collar bone (clavicle) is like the femur but lies in a different plane, instead of vertical, its horizontal.
- And notice how people break their clavicle (like my friend in rugby) its pretty much always from a force applied from the front going through you and this is through the compact bone at the perpendicular angle at which it buckles. (PLEASE CORRECT ME IF I AM WRONG)
So in summary, your question is too broad for there to be a specified answer, as you have to take into account genetics, diet/ nutrition, location in bod, angle of force applied.
