Muscle – Structure and Function

Skeletal muscles (Mus - Latin: a mouse) are bundles long fibers surrounded by network of connective tissue. There are over 640 muscles in our body. Fibrous ends of muscles, known as tendons, are attached to bones. Muscles contract and relax to bring about movement of part of body to which they are attached. Movements require coordinated activity of many muscles. Actions of voluntary skeletal muscles are controlled by respective centers in brain. They are under the control of will. Muscles in heart, bowel, urinary bladder and blood vessels are smooth and cannot be controlled by will.

Disorders of skeletal muscles are known as myopathies. Some of these are hereditary.
