What is the anatomy of skeletal muscles?
Despite the huge number of different muscles that attach and move the skeletal structure, the anatomy of skeletal muscles is essentially the same throughout the body. The skeletal muscles consist of long multinucleation cells that have cylindrical shapes. The muscles are almost always attached directly to the bones and, unlike the other two types of muscles, heart and smooth, are under voluntary control. Skeletal muscles have many layers and membranes that protect and distribute their different components. Multinucleation cells can also be called fibers that are grouped into bundles depending on the voluntary effect for which they control. The main function of Sarcolemma is to maintain all different cell components intact, in a way in which the cell membrane works in other cells of the body. Within the Sarolemma, Fluencing Muscle Cells, or Sarcoplasma, PL, Myofibril. Each individual fiber contains numerous myofibrils, which are protein strands that run along the entire length of muscle fibers. These structures lie side by sideU A are responsible for extending and infringing the muscle on the central nervous system signal (CNS).
myofibrils may be dissected to another component that is directly involved in contraction and extension of the fiber, sarcomer. Sarcomers act as small chains of contractile tissue, which are equal to the end-to-end throughout myofibile. At the microscopic level, myofibril is composed of an even finer source of protein called myofilament. Myofilament proteins consist of dark springs or anisotropic (a) belts and light springs or isotropic (i) belts; The contrasting color proteins are what gives the skeletal muscle its striped look. A-pools and myofilament i-persons are also responsible for the metabolism of adenosine triposphate (ATP), which initiates muscle contraction.
On the macroscopic level, the skeletal muscles are composed of different layers. The farthest is called epimysium and protects skeletonsMuscles before friction damage that could occur when moving against other muscles and bones. Epimysium is a particularly important part of skeletal muscle anatomy, because together with other connective tissues form muscle tendons. The muscle tendon is a strong, fibrous "ropes" that prevents the muscle to slide out of their bones.
