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
