How do signals travel in nervous control compared with hormonal control?
How does the speed of action differ between nervous and hormonal control?
Nervous control acts rapidly; hormonal control generally acts more slowly.
How does the duration of effects differ between nervous and hormonal control?
Nervous effects are generally short-lived; hormonal effects are generally longer-lasting.
