Although both cardiac and skeletal muscles are striated, skeletal muscle is composed of slow (type I) and fast (type II) fibers, whereas cardiac muscle consists of a single fiber type, most similar to type I skeletal muscle fibers. In contrast, smooth muscle cells are not striated but rather consist of dense bodies and intermediate filaments. Muscle tissue is subdivided into three broad categories: skeletal muscle, cardiac muscle, and smooth muscle.
