- Note thin fibers, with diameter not much greater than that of the nucleus (about 5 µm).
- Each fiber is an individual cell, with length ranging from 20 to half a millimeter (depending on location in the body).
- Individual fibers are often not readily distinguishable (unlike skeletal muscle, where individual fibers are huge and distinct).
- Nuclei are normally long and cigar-shaped (they may appear wiggly in contracted muscle).
