Answer 1

It is not advised to close the mouth by injecting cavity fluid into the corrugator muscle.

What does the corrugator muscle do and where is it located?

Near each eyebrow is a pyramid-shaped muscle called the corrugator supercilii, which is indicated by the arrow. The corrugator supercilii muscle moves the eyebrow downward and inward toward the inner corner of the eye and nose. The lower forehead's vertical lines and wrinkles are also produced by this muscle.

The mandible is what?

The largest, sturdiest, and only moveable skull bone is the mandible. It is sometimes referred to as the lower jaw bone because it makes up the lower jaw. Together with the maxilla, or upper jaw bone, it aids in the chewing process.
