What Is Skeletal Muscle?
Skeletal muscle is made up of very specialized cells that have the ability to
shorten when they are stimulated. With the exception of reflex mechan-
isms, such as the knee tap by a physician, movement of our skeletal
muscle is under the command of our brain, as mentioned earlier. Because
muscle cells are very long they are often referred to as muscle fibers.
 The fibers are bundled up like a box of dry spaghetti or
straight wires in a cable. The muscle fiber bundles are themselves bundled
up and are part of larger collection of similar bundles which make up a
particular muscle. Skeletal muscle is so named because it is generally
anchored at both ends to different bones of our skeleton by tendons.
When muscle contracts, it pulls on a specific bone, which moves the bone,
thus moving a body part.
