Sometimes when you learn how something works, you think, Thanks knowledge, that really helped, everything makes more sense, and other times you look up how wrists turn, and it's like WTF?!

@RickiTarr Your hand doesn’t have many muscles, it’s effectively a marionette puppet, being almost entirely puppeteered from near the elbow using strings (tendons).

Because besides a few of the adjustment motions (and) your thumb, most muscles for moving your fingers and forming grasps are all located in your forearm.

@analogist @RickiTarr

anybody who plays piano knows this. It's the part of your forearm that gets achy after a long practice session.

@analogist @RickiTarr One of my favourite “impress the kids” tricks is showing them how you can grab someone’s arm, just above the wrist, and make the fingers curl when you squeeze the tendons. Big laughs every time (or expressions of horror 😄)
