Abstract:
MicroRNAs (miRNAs) have emerged as important players in the regulation of gene expression, being involved in most biological processes examined to date. The proposal that miRNAs are primarily involved in the stress response of the cell makes miRNAs ideally suited to mediate the response of skeletal muscle to changes in contractile activity. Although the field is still in its infancy, the studies presented in this review highlight the promise that miRNAs will have an important role in mediating the response and adaptation of skeletal muscle to various modes of exercise. The roles of miRNAs in satellite cell biology, muscle regeneration, and various myopathies are also discussed.

Exercise and Muscle Performance
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
Formation of Muscle Fibers from Myoblasts
Muscle progenitor cells (MPCs) are formed from the myotomes. MPCs express genes that encode the transcription factors Pax3 and Pax7. Along with Pax 3/7, other transcription factors...
Microscopic Anatomy of Skeletal Muscles
The muscle sarcolemma is a plasma membrane enclosing each muscle cell that conducts electrical signals called action potentials. The sarcolemma extends into the cell to form T-tubules, ensuring the neural impulses are uniformly distributed across the entire muscle...
