Human bones serve as scaffold which support organs, protect organs and anchor muscles like the brain, heart and lungs. Without bones, life is not possible.

1.) An adult’s skeletal system is about up to 40% of the total body weight and water is half of this weight.

2.) Not all bones are connected. The only human bone in the human body not connected to another is the hyoid. The ‘hyoid’ is .a V-shaped bone located in the neck and serves as the point of attachment for the tongue.

3.) A newborn baby has more than 270 bones while an adult has more than 206 bones. Don’t be surprise because some of the bones fuse together as a person grows old.

4.) Have you figured out what is the biggest bone in your body? Well, the biggest bone in the human body is the ‘femur” which is located in the thigh.

5.) On the other hand, the smallest bones on the human body are the ‘stapes’ bone located in the middle ear.

6.) An average human adult has 206 bones. But as they always say, there are some exemptions. Some people have more pairs of ribs than other.  A normal person has 12 pairs while others have 13 pairs making them to have 208 bones in total.

7.) Most people believe that the bones in our body are not white. Actually, they range in color from light brown to beige. If you have already visited a museum, you’ll notice that they are white because they have been cleaned and boiled.

8.) There are 52 bones in our feet and this would simple means that they representing 25% of our 206 bones.

9.) The bones on our hands and feet account for about half of the bones in the human body.

10.) Our big toes have two bones each while the rest have three and they are actually amongst the most important elements within the body as they balance the skeleton and let us move forward when walking. Without our toes we would simply fall over.

11.) The largest bone in the human body is the pelvis which is commonly known as hip bone. Our hip is made of six bones joined firmly together.

12.) As already mentioned, the longest bone is the 'femur', in the thigh. It makes up almost one quarter of the body's total height.

15.) The nose and the ears do not have bones inside them. The inner supports of the nose and the ears are cartilage or gristle. These are lighter and more flexible than bone.

16.) Bones are harder than cartilage but when a person died the cartilage rots faster than bone. This is why the skulls of skeletons have no nose or ears.

17.) Comparatively, men tend to have slightly thicker and longer limbs and digit bones while women tend to have narrower rib cages, smaller teeth, less angular mandibles, less pronounced cranial features such as the brow ridges and external occipital protuberances (the small bump at the back of the skull), and the carrying angle of the forearm is more pronounced in females.
