» There are three types of muscle;
» Cardiac- in-voluntary the muscle that
encompass the heart
» Smooth- in-voluntary
» Skeletal- voluntary Provides Human
Movement, attached to the skeleton by
tendons
Divide the class into 3 (Cardiac/Smooth and Skeletal muscle):
- Find
a couple of images of the muscle
- Say what this type of muscle does
- Give a few examples
Be prepared to feedback your
findings to the class…
The heart has its
own muscle tissue
called
Cardiac/
Myocardium
muscle.
Function: the function of the
myocardium is to pump blood
around the body.
It beats

It is an Involuntary
muscle: as it has its own
nerve supply. It works
by sending nerve
impulses through the
cells and fibres within
the muscle.
Also an involuntary muscle

control.
Found in the digestive system (large
and small intestine), Circulatory
system (artery and vein walls) and
Urinary system.
Smooth muscle contracts consecutively
(peristaltic action), producing a
wavelike effect.
E.G. when food is passed through the
digestive system it is slowly squeezed
through the intestines.
Muscle that is attached to the skeleton across
joints…
It is under voluntary
control as we decide
when to contract the
muscles and produce
movement.
Skeletal muscle is responsible for the
following functions:
- Produce movement
- Maintaining body posture
- Generate heat for warmth
What else?
Co-ordinated contractions of
the skeletal muscle allow us
to move smoothly and
produce sports skills.
Over 700 skeletal muscles make up
40% of our body weight (slightly less
for females).
