Things I do not know what they're called :)

There are some random things that I do not know what they're called. One idle day, I just decided to check merriamwebster.com and finally started my quest to look for the things that I do not know what they're called. Maybe some of you might share the same sentiment. :p

Here are some samples:

1. Philtrum- I remember when I was younger I was teased because my friends cannot see the philtrum on my face. There was some saying before that if you do not have this on your face, you might hail from the family of monsters. haha.

8. Muntin- ok so it is not just called a window pane. It's MUNTIN

7. Glabella- I thought this is the same as the nose bridge! haha!

* Thanks to MerriamWebster for the info!!
