Smooth muscles contract very slowly, whereas skeletal muscles can contract at different rates. Skeletal muscles can be composed of fast-contracting fibers, slow-contracting fibers or a mixture of both.
Unlike Skeletal and Cardiac muscle tissue, Smooth muscle is. . Smooth muscle fibers are small and tapered-with the ends reducing in size, in contrast to the cylindrical shape of skeletal muscle. Each smooth muscle fiber has a single centrally located nucleus.he structure of these muscle tissues can be described from the level of detail of the muscle fibres (muscle cells) through all the other muscle structures and parts of structures that bind muscle cells together enabling them to perform their functions.
