I was reading about human muscles the other day, and came across this law that stated that if a muscle received a stimulus greater than a certain value (it was called a threshold stimulus), the muscle contracted with full intensity. Basically, that meant that either a muscle contracted with all the strength it possibly could (All) or it didn't contract at all (None). What I want to know is whether this law is applicable for all kinds of muscles (striated/striped, smooth and cardiac) or is it applicable for just striated. One of the books I looked up said that it was only true for striated ones which are voluntary, and another book said that it held true for all kinds of muscles and even held true for nerves. Help!
Re: The 'All-or-None' law for muscle contractions. Where does it work?
