Smooth muscle contracts relatively slowly
1. the only ATP available is supplied by fermentation
2. its contraction is stimulated by hormones, not motor neurons.
3. it does not have a well-developed sarcoplasmic reticulum, and calcium enters the cell through the plasma membrane during an action potential.
4. it is not striated

According to the sliding filament theory:
| 1. | Actin and myosin filaments slide over each other to increase the length of the sarcomere. |
| 2. | Length of A–band does not change. |
| 3. | I–band increases in length |
| 4. | The actin filaments slide away from A–band resulting in shortening of sarcomere |
