Voluntarily controlled is what type of muscle tissue

Skeletal muscle , attached to bones, is responsible for skeletal movements. The peripheral portion of the central nervous system CNS controls the skeletal muscles. Thus, these muscles are under conscious, or voluntary, control.

The basic unit is the muscle fiber with many nuclei. These muscle fibers are striated having transverse streaks and each acts independently of neighboring muscle fibers. Cardiac muscle tissue is found only in the heart, where cardiac contractions pump blood throughout the body and maintain blood pressure.

As with skeletal muscle, cardiac muscle is striated; however it is not consciously controlled and so is classified as involuntary. Cardiac muscle can be further differentiated from skeletal muscle by the presence of intercalated discs that control the synchronized contraction of cardiac tissues. Cardiac myocytes are shorter than skeletal equivalents and contain only one or two centrally located nuclei. Smooth muscle tissue is associated with numerous organs and tissue systems, such as the digestive system and respiratory system.

It plays an important role in the regulation of flow in such systems, such as aiding the movement of food through the digestive system via peristalsis.

Smooth muscle is non-striated and involuntary. Smooth muscle myocytes are spindle shaped with a single centrally located nucleus. Types of muscle : The body contains three types of muscle tissue: skeletal muscle, smooth muscle, and cardiac muscle, visualized here using light microscopy. Visible striations in skeletal and cardiac muscle are visible, differentiating them from the more randomised appearance of smooth muscle. Learning Objectives Describe the three types of muscle tissue.

Key Points The muscular system is responsible for functions such as maintenance of posture, locomotion, and control of various circulatory systems.

Skeletal muscle is also known as voluntary muscle because we can consciously, or voluntarily, control it in response to input by nerve cells. Skeletal muscle, along with cardiac muscle, is also referred to as striated "striped" because it has a microscopically streaked or striped appearance. You may want to write the following words onto your pillowcase: skeletal, striated, and voluntary. Perhaps doing so will permanently link these three words in your mind.

More likely, however, is that your landlord will make you replace your pillowcase. Title: File:Muscle Tissue 1. Title: File Skeletal Smooth Cardiac. Cardiac muscle is only found in the heart, and although it is striated like skeletal muscle, it functions involuntarily.

Cardiac and most smooth muscles are autorhythmic - they are capable of contracting spontaneously without nervous or hormonal stimulation.
