Question

why do our fingers curl when our hands are at rest?

In: Biology

Answer 1

The muscles that control your fingers need to be at rest at the point directly between fully open and fully closed, in order to allow ample movement both ways. If they were fully outstretched at rest, the closing of your hand would take twice the effort by those muscles and your arm would look considerably different.
