The muscular system is an organ system consisting of skeletal, smooth, and cardiac muscle. It permits movement of the body, maintains posture, and circulates blood throughout the body. The muscular systems in vertebrates are controlled through the nervous system although some muscles (such as the cardiac muscle) can be completely autonomous. Together with the skeletal system in the human, it forms the musculoskeletal system, which is responsible for the movement of the body. There are three distinct types of muscle: skeletal muscle, Alpha Surge Male testosterone support cardiac or heart alpha surge male muscle builder, and smooth (non-striated) muscle. Muscles provide strength, balance, posture, movement, and heat for the body to keep warm. There are more than 600 muscles in an adult Alpha Surge Male deals human body. A kind of elastic tissue makes up each muscle, which consists of thousands, or tens of thousands, of small muscle fibers. Each fiber comprises many tiny strands called fibrils, Alpha Surge Male deals impulses from nerve cells control the contraction of each muscle fiber.
