| Skeletal muscles are just one of the striated muscle tissues that basically comprise the voluntary movements of the human body. These muscles are attached to bones through tendons and always work in pairs just so as to bring about movement through contraction and relaxation. They consist of long, cylindrical fibers and therefore have a characteristic banded appearance due to the arrangement of myofilaments within the muscle fibers. Skeletal muscles have as one of their most important functions to make the body walk, run, lift, and dance. The other important function of skeletal muscles is the stabilization of posture during movement. Contraction force in skeletal muscles can be finely regulated to be either tremendous in strength or fine in detail. Definition of skeletal muscles states that they are under conscious control and can initiate action on basis of signals given out by the central nervous system. So, at every signal transmitted by the motor neuron, it calls up the muscle fibers to contract, and, hence, movement generation is the outcome. Such accuracy and complicated movements lead to the successful performance of daily activities and athletic performances. In addition to that, skeletal muscles enhance overall metabolic fitness. They are one of the heat-producing tissues for the body, and its contraction along with using glucose is the metabolism, thereby oxidizing fats. |
