Muscle
- 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.
