Muscle+Anatomy

There are three types of muscles. Skeletal, smooth and cardiac. Skeletal muscles look like a lot of long fibres that are thinner than a hair. The smooth muscle is a lot shorter than a skeletal muscle and looks smooth with no stripes. Cardiac muscles are striped like skeletal muscles. They have a similar internal arrangement but their fibres have branches. Smooth muscles surround organs and pipes. E.g. Digestive tract, bladder, stomach, arteries and veins. Your heart is a cardiac muscle and your skeletal muscles are attached to your bones. Involuntary muscles are smooth muscles that you’ve got no control over. E.g. Mechanical digestion in the stomach occurs through the action of the smooth muscle in the stomach wall. Superficial muscles are skeletal muscles that are located near the body’s surface above the layers of deep muscles.
