which part of the bone is a hollow cylinder that makes the bone strong?

The part of the bone that is a hollow cylinder and helps make the bone strong is the diaphysis , which is the shaft of a long bone.

Quick Scoop

• Long bones (like the femur and humerus) have a central shaft called the diaphysis.

• The diaphysis is shaped like a hollow cylinder made of compact bone, which gives strength while keeping the bone relatively light.

• This hollow design resists bending and twisting forces efficiently, helping the bone stay strong without being too heavy.

So if you see the question “which part of the bone is a hollow cylinder that makes the bone strong?” the correct answer is: Diaphysis.
