Multiple fiber summation
Article quote: "When a weak signal is sent by the CNS to contract a muscle, the smaller motor units, being more excitable than the larger ones, are stimulated first. As the strength of the signal increases, more motor units are excited in addition to larger ones".
I find the last sentence to be unclear. What does "when the strength of the signal increases" refer to? An increased frequency? Or amplitude? Or Number of firing neurons?
Can anybody help?
Cardiac Muscle
What is the citation for the paper saying that the temporal summation of 30,000 Ca++ ions is what causes the intracellular calcium increase. Obviously more Ca would cause a higher concentration, but where does the number 30,000 come from
