Question

compare the shapes of the bones of the human skull with shape of the bones of the human leg. Why is their shape important?

Answer 1

the human skull is one of the thinnest bones in the human body and is not meant for supporting very much weight or for absorbing shock like a human femur, tibula, or fibula.

 the rounded shape of the skull is meant to hold a brain while the cylindrical shape of a "leg bone" is made for support and shock absorption.
