Cortical bone is also known as a compact bone, this bone is one of the 2 types of bone found in human body one is compact and the other one is cancellous(spongy) is always found in deep cortical bone and serves as an internal support structure.

In compact part, it has some functional units and this functional units we called as asteon.
Asteons sometimes called as haversian system and thats because of their shape and it runs parallel to the first axis of the bone.
In osteon we can find collagen fibers within bone matrix run in seperate direction which is actaually provide torsion strength to the bone.
we have haversion canal at the cetre of each osteon so we acn call it as central canal. it supplies oxygen to blood cells and nerves.
volkmann's canal also there in cortial at right angle to the central, this going to allow all of the connection for the haversian system.
canaliculi connects the lacunae and osteocytes in cortial.

we can say that cortaial is very strong from oueside and have a spongy structure from inside so it supports for bending, compression , tension, torsion.
