Will get brainiest

The number of muscles in our body varies from around 640 to 850. What are some factors that would keep those numbers so far apart? Maybe age? As you age does the amount of muscles in your body change? How come there aren't a set amount?

Respuesta :

age, and size would both affect the number of muscles a person has
Age, size and excercise are various reasons why. And we are all different.
