What is the strongest organism

Where is the hardest bone in the body?

Temporal bone protects the inner ear

It is a rather small bone that sits in a place that cannot be seen from the outside, namely on the inner ear. It is the so-called petrous bone. It protects the inner ear and thus also the balance organ and the auditory nerves. And precisely because this bone is so small, it is also so hard. Because suppose we hit our skulls or someone hits our ears, then this bone, which protects very important nerves in a small space, should not be deformed, otherwise the nerves will be pinched - with all the negative consequences for the hearing or our balance.

Thigh or shin: less hard and therefore less brittle

It is a fallacy to think that the big, strong bones are also the particularly hard ones - thighs or shins. Of course they have to endure a lot, but they do that by mass. In addition, the hardness of a material does not say anything about its strength. Hardness is the ability to withstand a deformation when external forces act. And it is actually more like this: Particularly hard materials are usually also brittle at the same time. That means that they can withstand a lot, but that also makes them immobile. So if a strong force does act, they break faster than softer materials, which can give way to the pressure. In the case of bones such as the thigh or the shin, it would not be so good if they were extremely hard, because then they could break faster under higher stress.
