Striated Muscles

Striated Muscles

 

contractile tissue consisting, unlike smooth muscle, of symplasms, or multinuclear muscle fibers covered by a thin membrane, the sarcolemma.

Striated muscles have transverse striation caused by the alternation in their myofibrils of portions with different physicochemical and optical properties. Striated muscles make up the skeletal (truncal, or somatic) musculature and certain other muscles in vertebrates. Among invertebrates, striated muscles are found chiefly in arthropods. The main function of striated muscles is to move the body or its individual parts in space.

Histologic smooth muscle abnormalities are poorly documented in MD, and it has been hypothesized that such an involvement might precede changes in striated muscles. Some studies have suggested that neurological abnormalities or visceral neuropathy involving substance P and enkephalin-immunoreactive fibers of the smooth muscle play a role (2,5-6).

The disease is caused by mutations in the dystrophin gene 3 that encodes the sarcolemmal protein product, a part of the dystrophin glycoprotein complex and also contacts the motor protein actin to the cytoskeleton.7 It gives mechanical firmness to striated muscles.8 Deficiency of dystrophin, collapses dystrophin glycoprotein complex thus leading to instability of muscle cell membrane, abandoned calcium influx sterile inflammation, and advanced muscle degeneration.9,10 The masticatory muscles are involved later along with time span while the oro-facial muscles are affected approximately after 2 years resulting in muscle imbalance and severe craniofacial and dental abnormalities.11
