Question

Which muscle extends from the corners of the mouth to the cheekbone; called the smiling muscle?

Answer 1

Zygomaticus Major

Explanation:

Zygomaticus Major is the name of the muscle which is responsible for our smile.

You have to know one thing, the name of cheek bone is Zygomatic arch. So I suppose you can see that anything related with cheek has "Zygomatic" in its name.

So suppose that you forget the name of the muscle and you have to answer it in the question. So just write Zygomatic Muscle and you will likely get marks.

The motive of telling you this was that search the internet for such keywords and when you have to search for a specific bone, or muscle, or process, type the name of the keyword and then you can narrow the location.
