The human skeleton has several functions including providing structure, producing blood cells, storing minerals, and protecting organs. Babies have around 350 bones that fuse together into 206 bones for adults. The spine anchors all other bones and is made of 33 vertebrae. There are different bone types including long, short, flat, irregular, and sesamoid. Joints connect two or more bones and can be categorized by connection type and mobility, including little mobility, slight movement, and freely movable joints.

3. Some Facts About Human
Skeleton
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.
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.

4. The human skeleton account for about 20
percent of an regular sized persons total body
weight.
There are different type of bones; long bones,
short bones, flat bones, irregular bones and
sesamoid bones.
The largest part of our skeleton is the femur,
which is the upper part of our thigh.
The smallest bone in the human body is the
stapes bone which is located in the ear. It is less
than 3mm long.

5. 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.

6. By mobility, the types are called
synarthrosis(little or no mobility),
amphiarthrosis(slight movement) and
diarthrosis(freely movable).
If a rib is removed it can regenerate itself within
3 months.
The only jointless bone in the human skeleton is
the hyoid bone which is found in the throat.
