Journeys: Skeleton. Stop 3

Finger joints

Experiment! Bend your pointing finger and count how many places it bends.

Yes, three joints!

Count again, bending your finger slowly.

Now bend your thumb. How many times does it bend?

Yes, two! The thumb has one bone fewer.

Bend your thumb again and count the bends.

Each hand has 27 little bones. That's why fingers are so nimble they can even hold a needle.
