Is this also when you’re asleep or dead? Why is it like this?
In: Biology
Because they have muscle tone, which is “continuous and passive partial contraction of the muscles”. All of your muscles have muscle tone, unless your are suffering from a disease of muscle tone insufficiency. Notice how your arms don’t hang straight down. That is also because of muscle tone.
Fingers are light, compared to arms, so they curl up under the same amount of muscle tone.
your finger is moved by two sets of muscles that act opposite to each other, one set extends your finger while the other folds it
usually those muscles are in balance, so it is sort of a middle ground, half curled
same goes with pretty much any part of your body – your abs are curling you forward, your erector spinae muscle set curls you backwards
that’s why complex exercises like deadlifts, squats, etc are much better than isolated ones, they work on both sets of musclesgroups
