The muscular system controls numerous functions, which is possible with the significant differentiation of muscle tissue morphology and ability. The muscular system is made up of muscle tissue and is responsible for functions such as maintenance of posture, locomotion and control of various circulatory systems. This includes the beating of the heart and the movement of food through the digestive system. The muscular system is closely associated with the skeletal system in facilitating movement. Both voluntary and involuntary muscular system functions are controlled by the nervous system.
Cardiac muscle appears striated due to the presence of sarcomeres, the highly-organized basic functional unit of muscle tissue. Cardiac muscle, like skeletal muscle, appears striated due to the organization of muscle tissue into sarcomeres. While similar to skeletal muscle, cardiac muscle is different in a few ways. Cardiac muscles are composed of tubular cardiomyocytes, or cardiac muscle cells. The cardiomyocytes are composed of tubular myofibrils, which are repeating sections of sarcomeres. Intercalated disks transmit electrical action potentials between sarcomeres. A sarcomere is the basic unit of muscle tissue in both cardiac and skeletal muscle.

Muscle Contractions: How Neurotransmitters And Chemical Reactions Move Muscles And Bones
How do the bones of the human skeleton move? Skeletal muscles contract and relax to mechanically move the body. Messages from the nervous system cause these muscle contractions. The whole process is called the mechanism of muscle contraction and it can be summarized in three steps:.
Muscle Lab Learning Objectives Identify the histological landmarks of skeletal muscle Contrast the structure and function of skeletal, smooth, and cardiac muscle tissue.
T-tubule biogenesis and triad formation in skeletal muscle and implication in human diseases
Skeletal muscle , also called voluntary muscle , in vertebrates , most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons , and they produce all the movements of body parts in relation to each other. Unlike smooth muscle and cardiac muscle , skeletal muscle is under voluntary control. Similar to cardiac muscle, however, skeletal muscle is striated; its long, thin, multinucleated fibres are crossed with a regular pattern of fine red and white lines, giving the muscle a distinctive appearance. Skeletal muscle fibres are bound together by connective tissue and communicate with nerves and blood vessels.
