Journeys: Muscles. Stop 5

The stubborn finger

Experiment! Put your hand flat on the table and fold your middle finger underneath.

Now try to lift your ring finger. Did it work? Tap the picture!

Wow! Your fingers are really bendy. Hardly anyone can do that.

It doesn't work, does it? It's the same for almost everyone.

One muscle lifts the middle finger and the ring finger, and their tendons are tied together by a strap. So one won't lift without the other.
