work like
a simple machine

Types of muscle tissue
 Skeletal
muscle
tissue: is attached
to bones by
tendons, is
associated with
the body's
voluntary
movements. It is a
striated muscle.
Unlike cardiac
Types of muscle tissue
 Cardiac
muscles:
it is found in the
heart. Cells are
joined to one
another by infused
discs which allow
the
synchronization of
the heart beat.

muscle:
is found in various
parts of the body
such as the arteries,
the bladder, the
digestive tract, as
well as in many other
organs.
Muscle action and energy
 Whenever
you
move any of your
body parts you
muscles us an
energy called
glucose.
 When bonds in
glucose brake, the
muscle retracts.
