Compare the "all or none" implications for muscle contractions as compared to other topics in neuroscience where this concept applies.

What will be an ideal response?


"All or none" typically means that an action either occurs or it does not; it is not smaller for a weaker stimulus versus a stronger stimulus. However, in the case of muscle contractions, if fewer motor units are involved and firing, the muscle will still contract but it will be weaker as compared to when more motor units are firing.
