Body Parts... what's that called?

Hey there English learners! I hope you're all doing well!

Here's an image I work with to label some body parts:

Do you know them all??

Let's go ahead and list them...
1. palm (the inside of your hand)
2. wrist
3. eyebrow
4. neck
5. forehead
6. eye-lid
7. cheek
8. chin
9. shoulder
10. thumb (don't forget that the 'b' is silent!)
11. toe
12. elbow
13. chest
14. waist
15. thigh
16. knee
17. ankle
Did you know them all? Which didn't you know?
Which do you find most difficult to remember?
In my experience it's 'thigh'. Also, many confuse 'wrist' and 'waist'.

Practice makes perfect!
