Answer:
skeletal muscles
Step-by-step explanation:
Striated muscle (skeletal muscles)
The striated muscle is a type of muscle whose fundamental unit is the sarcomere, and which, when viewed through a microscope, shows stretch marks that are formed by the alternate light and dark bands of the sarcomere. It is formed by spindle-shaped muscle fibers, with very sharp ends, and shorter than those of smooth muscle. These fibers have the property of plasticity, that is, they change their length when they are stretched, and they are able to regain their original shape, allowing them to adapt better to resistance training. To improve the plasticity of the muscles, stretching is useful. He is responsible for the movement of the axial and appendicular skeletons and the maintenance of posture or body position. In addition, the ocular skeletal muscle executes the most precise movements of the eyes.
The musculoskeletal tissue is made up of very long (up to 30 cm), cylindrical and plurinucleated cell bundles, which contain abundant filaments, the myofibrils. The diameter of skeletal striated muscle fibers ranges from 10 to 100 micrometers. These fibers originate in the embryo by the fusion of elongated cells called myoblasts. In skeletal muscle fibers, the numerous nuclei are located in the periphery, near the sarcolemma. This characteristic location helps to differentiate the skeletal muscle from the heart muscle because both show striations but in the heart muscle the nuclei are central.
