2.  Allows for movement of the body.
Keeps head in position.
 Provides heat.

4.  Contraction of skeletal muscle is responsible
for the overall movements of the body.

5.  Skeletal muscles constantly maintain tone,
which keeps us sitting or standing erect.

6.  Muscle of the thorax are responsible for the
movements necessary for respiration.

7.  When skeletal muscle contract, heat is given off
as a by-product.

8.  The contraction of cardiac muscle causes the
heart to beat, propelling blood to all parts of
the body.

10. There are
nearly 650 skeletal

11.  Smooth muscle is found in our internal
organs: in our digestive system, our blood
vessels, our bladder, our respiratory organs
and, in a female, the uterus.
 Smooth muscle can stretch and maintain
tension over extended periods
 Smooth muscles are involuntary muscles - in
other words we do not have to think about
contracting them because they are controlled
automatically by the nervous system.

12.  As the name should tell you, cardiac muscle is
found only in the heart.
 It can stretch, just like smooth muscle,
and contract like skeletal muscle.
 Like smooth muscle, cardiac muscle
is involuntary.
