The Human Body by Zoe

I have found some information about the human body please comment and tell me what you think                                                                                                                                                         Bones

 

Bones give us shape and a framework for vital organs to be stored safely inside .

What are the functions of the Skeleton?

The three functions of the skeleton are:

  1. Support
  2. Protection and
  3. Movement

The skeleton maintains a body shape, protectsvital organs, and provides a system of muscle levers that allow body movement.

Humans (and some other animals) have bony skeletons inside their bodies which grow.

Without our bones, we couldn’t stand, walk, run, or even sit.

How many bones does the human body contain?

An adult skeleton contains 206 bones and the skeleton of an infant contains 350. As a child grows, bones fuse (join) together to make longer bones.

What is the longest bone?

The longest bone in our bodies is the femur (thigh bone).

What and where is the smallest bone?

The smallest bone is the stirrup bone inside the ear.

How many bones in a hand?

There are 27 bones in the human hand. The carpus or wrist has account for 8; the metacarpus or palm contains 5; the remaining 14 are digital bones; fingers and thumb.

What do the bones do?

Our bones provide support for our bodies and help form our shape.

They protect our organs against injury and enable us to move.

Some bones protect parts of the body, as the skull protects the brain, whilst others work together to make body parts move, such as the arm and leg bones.

Bones manufacture blood cells and store important minerals.

Quick Fact: If we didn’t have a skeleton we would be wobbly jelly blobs that would find it hard to move. Our skeleton supports our body .

Joints

Bones are connected to other bones at joints.

There are many diffrent kinds of joints including:

  • fixed joints (such as in the skull),
  • hinged joints (such as in the fingers and toes), and
  • ball-and-socket joints (such as the shoulders and hips).  here are some examples about the X-ray

Your skeleton:

  • supports your body and gives it shape.
  • protects the soft and squashy bits of you.
  • has muscles attached to it.
