Cardiac Muscle Smooth Muscle Skeletal Muscle
We are doing our project on the
muscular system.
There are three different types of
muscles in the human body,
there is the cardiac muscle,
skeletal muscle and smooth
muscle.
The main organs that make up the
Muscular system are : the Cardiac
muscle or the heart and the
skeletal muscle.
Here is a
picture of the
skeletal
muscle
There are two main organs in the muscular
system.
The skeletal muscles: the skeletal muscles
main function is to allow the human body to
move.
The cardiac muscles: the cardiac muscle is
actually the heart and we need the heart
because it pumps all the blood around our
body and allows us to breathe.
We perform these
functions by
doing anything
like walking,
running,
jumping,
playing sport etc.
The muscular system is practically
located everywhere in the human
body, here is a picture to show you
where:
The muscular system is very
important to the human body
because without our muscles we
wouldn’t be able to move
anything!
The main function of the
muscular system is to move
our bodies, they also help
move food from one organ to
another.
The muscular system’s role
is to control all our
movements that we make,
muscles are often called the
machines of our bodies!
There are a few things that can go
wrong with the muscular system
like, a hamstring injury, if you do
sport and you haven't stretched
right you could tear your muscles
and they can get stretched to far,
etc.
No, no one could because in order to
breath you need muscles, in order to
move you need muscles, the heart is
a muscle and you couldn’t live
without it and they also help move
food from organ to organ.
Cardiac Muscles:
Skeletal Muscles:
-The cardiac muscle is only found In the heart.
-There are roughly 650
skeletal muscles in the
human body.
-It can stretch like smooth muscles and contract
like skeletal muscles.
-The cardiac muscle only does short and single
contractions.
Smooth Muscles:
-Smooth muscles are actually found in out
internal organs our digestive system, our
bladder and our blood vessels.
-We don’t have to think about contracting our
smooth muscles because they are automatically
controlled by the nervous system.
-skeletal muscles are
attached to the skeleton.
-skeletal muscles work
in pairs, one muscle
moves the bone in one
direction and the other
moves it back again.
MUSCULAR DYSTROTHY: Muscular Dystrophy (MD) is a
disease that makes the muscle fibers become
damaged easily and it and it makes your skeletal
muscles weaken. There are over one hundred different
types of diseases that are very similar to Muscular
Dystrophy. There are currently no cures for Muscular
Dystrophy.
MYOPATHY: Myopathy is a muscular disease that makes
your muscle fibers not work, which makes most of your
muscles weaken.

1. When you smile you use seventeen muscles
and when you frown you use forty two!
2. Muscles weigh about forty percent of your
body weight and sometimes when we
exercise or train we put on weight rather
than losing it, because we put on muscle
weight!
3. Muscles can’t push, they can only pull!
We hope you enjoyed it!!!
