Directions: Read the passage below. On another piece of loose-leaf, create RECALL NOTES for the three types of
muscles: SKELETAL, CARDIAC AND SMOOTH. Include information about where they are located, whether it is
voluntary or involuntary, striated or not striated and any other important information.
The muscular system allows us to move. Each muscle in the body is made up of muscle fibers. Muscle fibers are long,
thin cells that can do something that other cells cannot do—they are able to contract, or shorten.
The muscles that are attached to your skeleton are called skeletal muscles. Skeletal muscles are voluntary muscles. These
muscle fibers have a striated, or striped, appearance due to the proteins called actin and myosin. When muscles contract, these
protein filaments slide or glide past one another, shortening the length of the cell. When your muscles relax, the length extends
back to the previous position.
Skeletal muscles are attached to your bones by strong tissues called tendons. The tendons on the end of the muscle attach
firmly to the bone. As the fibers in a muscle contract, they shorten and pull the tendon. The tendon, in turn, pulls the bone and
makes it move.
There many skeletal muscles in your body. In each of your shoulders is a deltoid muscle. Your deltoid muscles help you
move your shoulders every which way — from swinging a softball bat to shrugging your shoulders when you're not sure of an
answer. The pectoralis muscles are found on each side of your upper chest. These are usually called pectorals or pecs, for
short. When many boys hit puberty, their pectoral muscles become larger. Many athletes and bodybuilders also have large
pecs. Below these pectorals, down under your ribcage, are your rectus abdominus muscles, or abdominals. They're often called
abs for short. When you make a muscle in your arm, you tense your biceps muscle. When you contract your biceps muscle, you
can actually see it push up under your skin. Your quadriceps, or quads, are the muscles on the front of your thighs. Many
people who run, bike, or play sports develop large, strong quads. And when it's time for you to take a seat? You'll be sitting on
your gluteus maximus, the muscle that's under the skin and fat in your behind!
Smooth muscle is found inside some organs, such as the intestines and the stomach. Smooth muscles are involuntary. For
example, smooth muscles line your stomach wall and push food through your digestive system. Smooth muscle fibers are not
striated and are not as long as skeletal muscle fibers.
Your heart is made of cardiac muscle. Like smooth muscle, cardiac muscle moves without conscious control. Like
skeletal muscle, cardiac muscle is striated. Each cardiac muscle cell has a branched shape. The cells of the heart connect in a
chain. These chains form webs of layered tissue that allow cardiac cells to contract together and make the heart beat.
