Human Skeleton Anatomy – 10 Facts About the Human Skeleton!

The skeleton system is what holds everything together. In this article, I will share some fun trivia in relation to human skeleton anatomy and physiology.

Babies have around 350 individual bones, while a grown up adult has 206. The reason for this is because many bones fuse together as we grow older. Examples are the cranium and the pelvis.
The spine is in a way the base of our skeleton and anchors all other bones. It is composed of 33 small bones called vertebrae.
The largest part of our skeleton is the femur, which is the upper part of our thigh, while the smallest is the stapes bone.
The human skeleton account for about 20 percent of an regular sized persons total body weight.
The functions of the skeleton is not only to be a framework for the body, but it also produces red and white blood cells, stores minerals and protects vital organs.
There are different type of bones; long bones, short bones, flat bones, irregular bones and sesamoid bones.
The bones come in 2 different categories, the compact bones(also known as dense bones), and trabecular bones(also called spongy bones). The compact type contributes to about 80 percent of total bone mass.
Joints are where two or more bones connect. There are 2 different ways of categorizing joints, by the way they connect and by mobility.
In structural classification, the types of joints are fibrous joints(joined with fibrous tissue), cartilaginous joints(joined by cartilage) and synovial joints(not directly joined).
By mobility, the types are called synarthrosis(little or no mobility), amphiarthrosis(slight movement) and diarthrosis(freely movable).
