not sure but it comes from Latin word for yoke
--well actually it comes from a greek word . In fact in greek, it's called "zygomatikO" which comes from the verb "zyg-O-o" which means to bond two things together. So, in our case, zygomatico means (the bone) which bonds the skull to the maxilla.
ZygOs also means "yoke", so either explanation is possible -because yoke is similar in shape with the two zygomatic bones, if you see them from the front (both of them)
But, I think philologists say it's from the verb (hence, because it bonds skull to maxilla)
*I'm from Greece and a medical student
the verb in greek is "ζυγ-ο-ω", and the bone "ζυγωματικό"
A zygoma is the anatomical name for the cheekbone.

The Zygomaticus (Zygomatic Bone) Is incontrol of you cheekbones. Which articulates with the Frontal, Maxilla, Sphenoid, and Temporal Bones.
It is primarily the zygomaticus major and risorius muscles that are responsible for a smile, aided in part by the action of the buccinator :)

Smiling is a facial expression, so the skeletal muscles of the face would be used. In particular the zygomaticus. or the ****** it makes me smile
zygomaticus
There are a couple insertion points of the zygomatic bone. It's insertion points are on the orbicularis oris. This is very close in proximity to the zygomaticus major, as well as just above it.
