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.
The two attachment points are the origin and insertion. The origin is the immovable (or slightly moveable point. The insertion is the movable point. The insertion always moves towards the origin.
The tongue and the Penis do not have any insertion points that i am aware of.
Zygomaticus
The muscle that has an origin on the zygomatic bone and inserts into the orbicularis oris muscle is the zygomaticus major muscle. This muscle helps in lifting the corners of the mouth when a person smiles.

Muscles in the human body attach to bones at specific points called insertion and origin points. Insertion points are where muscles attach to bones and move during contraction, while origin points are where muscles attach to stationary bones. These attachment points allow muscles to create movement and perform various functions in the body.
The Zygomaticus is the primary muscle used in smiling.
It is primarily the zygomaticus major and risorius muscles that are responsible for a smile, aided in part by the action of the buccinator :)
Zygomaticus is your smiling muscle
Both the origin and insertion points attach muscles to bone. The muscles are moving the bones so they must be attached directly to bone.
The origins of muscles involved in muscle insertion are where the muscles begin and attach to bones or other structures. The functions of these muscles are to generate force and movement by contracting and pulling on their insertion points.
There are two points of attachment for a (skeletal) muscle, the origin and the insertion. The origin is the immovable (or slightly movable) part. The insertion moves towards the origin.
