The most fragile bone in your body is the clavicle or collar bone because it is a tiny bone that runs horizontally across the breastbone and collarbone and is very simple and easy to shatter.
The hardest bone of the human body is the jawbone.
The human skeleton actually renews once every 3 months and the human body consists of over 600 muscles and the human bone is as strong as steel but is 50 times lighter than steel.
The part of the human body that has no bones is the ears, nose tips, tongue and the penis.
Despite slang terms that imply otherwise, the human penis contains no bones.
The same cannot be said for many of our closest evolutionary relatives: Chimpanzees and bonobos both have penis bones (a macaque one is pictured), also known as bacula.
The adult human skeleton is made up of 206 bones.
These include the bones of the skull, spine (vertebrae), ribs, arms and legs. Bones are made of connective tissue reinforced with calcium and specialized bone cells.
There are an equal number of bones in the bodies of men and women (206), including the number of ribs.
The skeletons of men and women have some minor variations.
For example, the pelvis of a woman is more rounded.
Male and female bodies have different bone mass, density, structure, and length.
Female bones are lighter, and their pelvic cavities are broader to support childbirth, whereas male bones are heavier and sturdier.
Women's elbows and shoulders also are slightly different from men's.
Our arms bend a little further from our bodies and are more mobile at both joints.
Greater exposure to androgens in utero leads to a 4th (ring) finger that is longer than the 2nd (index), as often seen in men.
Women also have a longer Torso than men.
