MUSCLES
|
|
An animal that is alive is never
completely still. |
|
|
|
|
|
At rest or even asleep, animals
like ourselves still breathe because the lungs are moving. |

|
|
|
Blood is pumped round the body
by the heart. |

|
Muscles make all the movements
possible. |

HOW
DO THEY DO THIS?
|
|
Inside
your body you have a skeleton.
Your
skeleton does three important things.
1.
It protects the delicate parts.
2.
It supports your body
3.
It lets you move.
Your
muscles are attached to your bones and your bones have joints
to enable you to bend.
Muscles
and joints work together to allow movement.

Muscles
can be divided into three kinds:
Skeletal
muscles
Smooth
muscles
Heart
muscle
SKELETAL
MUSCLES
These are
sometimes called VOLUNTARY MUSCLES.
Skeletal
muscles enable us to walk and to talk.
Skeletal
muscles work when we want them to work.
A skeletal
muscle may stretch from one bone to another or from a bone to
the skin.
Somtimes
a skeletal muscle is not attached directly to the bone but is
linked to the bone by a tendon.
WHAT
IS A TENDON?
Tendons
are made out of strong fibrous tissue.
Tendons
are not elastic and do not stretch.
