What is the noun explanation of the five senses in the sketch?

The five senses in the sketch refer to: eyes, ears, nose, mouth and eyebrows.

In fact, eyebrows are one of the five senses. There are three divisions in the principle of "three divisions and five eyes" in the sketch avatar: chin to the bottom of nose, bottom of nose to the arch of eyebrow (roughly the position of eyebrow is the bone part attached to eyebrow), and arch of eyebrow to hairline. Five eyes means that the width of a person's face is five eyes when viewed from the front.

I hope it helps you.
