Document Summary
Introduction: myology study of muscle tissue, muscular tissue accounts for ~45% of total body mass, most of the work generated by the body. Functions of muscular tissue: body movements through skeletal system, body stability, storing and moving substances (food, hormones, producing heat. Nerve and blood supply: neurovascular bundle, nav, somatic motor neurons neurons (nerve cells) that stimulate skeletal muscle fibers to contract. Muscle proteins structural: structural proteins contribute to the alignment and stability of properties, titin, myomesin, and dystrophin are key structural proteins. Nerve and blood supply: most skeletal muscles receive one nerve that supplies them with motor and sensory functions, other muscles (e. g. , sheet-like muscles of the body wall) receive multiple nerves intercoastal nerves, neuromuscular bundle. Contraction of skeletal muscle fibers: nerve impulses cross the nmj from the somatic neuron to the sarcolemma, muscle impulses move inside the muscle fiber via the t tubules, ca++ couples electrical excitation to contraction.
