WebMuscle tissue is composed of cells specialized for contraction. Muscle is classified into three types according to their structure and function: Skeletal muscle cells - striated, voluntary control. Cardiac muscle cells - striated, involuntary control. Smooth muscle cells - nonstriated, involuntary control. Fig 021 Muscle Types. Web1 de abr. de 2000 · 0.027. Table 2. Longitudinal changes in isokinetic muscle strength in older men after 12 yr.
