Skeletal Muscle is one of
several terms used to refer to muscle tissue that is under conscious control.
that refer to the same tissue are Voluntary Muscle & Striated
The functions of skeletal muscle include:
- Producing movement
- Maintaining posture
- Stabilizing joints, and
- Generating heat.
Skeletal Muscle tissue is known as:
- Skeletal Muscle - because it is attached to the skeleton
and therefore moves bones in relation to other bones.
- Voluntary Muscle - because it is under conscious, or "voluntary" control.
- Striated Muscle - because the myofibrils that
form this type of muscle appear to consist of "band" (of lighter and
when viewed under a microscope. These are due to the alternation of actin and myosin protein filaments within each myofibril, and form
the visual impression of striations in
the muscle tissue.
Other types of muscle tissue:
There are three main types of muscle tissue.
- Skeletal Muscle (see above) - muscles that move bones, under conscious control.
- Smooth Muscle - surrounding organs and other body structures, not under conscious control.
- Cardiac Muscle - the specialized muscle found only in the heart.
