Introduction :- Muscle cells are also known as myocytes and these are of different types :- skeletal muscles , Smooth muscles , cardiac muscles etc . The main function of the muscle cells is their property of contraction and relaxation by formation of cross-bridges ( by the help of protein actin , myosin , troponin , tropomyosin ). Skeletal muscles are voluntary in nature while the smooth and cardiac muscles are involuntary in nature . Muscle oxygenation is defined as the rate of oxygen usage and supply to muscle tissues for their proper functioning .Answer :- Muscular system of our body is mainly and directly responsible for the production of different types of movement due to their contraction and relaxation property . So , the movements are produced by the muscular system. Muscle cells are contractile tissue and are derived from the mesodermal layer of embryonic germ cells. Muscle is composed of muscle cells called muscle fibres. Myofibrils contain sarcomeres which are composed of myosin and actin proteins . These two proteins plays a major role in the contraction of muscle cells .The distance at which the diffusion is effective for oxygenating a muscle cell is depends upon the distance that the oxygen molecule takes to travel towards the muscle cell. And , If the oxygen travels more distance then the rate of diffusion decreases gradually. Explanation :- We know that the distance at which the diffusion is effective for oxygenating a muscle cell is depends upon the distance that the oxygen molecule takes to travel towards the muscle cell , that's why when the oxygen travels more distance then the rate of diffusion decreases gradually. Muscle fibers are surrounded by number of capillaries which are useful for the diffusion of oxygen. Actively working muscles are not affected by the diameter of the muscle fibers, because theses muscle contains large number of capillaries.
