3. Skeletal Muscle
The skeletal muscle
tissue composes
muscles attached to
the bones. They are
under voluntary
©27 control, so just about
everything you do with your body is controlled by
these muscles. They function all the time to
maintain your posture, or even express a facial
expression. They can also be called striated
voluntary muscle, meaning it is striped and it is
under willed control.

4. Smooth Muscle
Smooth muscles are
found on the inside walls
of hollow muscles
(stomach, intestine etc.).
They are long and narrow
fibers with a nonstriated
©28 appearance.
Another name for the smooth muscle is nonstriated
involuntary muscle, because there are no striations
and it cannot be controlled by will.

5. Cardiac Muscle
Also known as striated
involuntary muscle, the
cardiac muscle have cross
striations and dark bands
called intercalated disks. The
gap junctions between the
disks allow for communication
©29 channels between the cells. As
their name states, they line
the wall of the heart.
