Is there a name for the visible part of the breast that extends up to the clavicle and underarm?

Searches on line have no names for visible parts of the breast, no matter what search words you use. All you get are descriptions of interior structures like nodes or articles about cancer or plastic surgery.

Are there names for the underside crease or any other exterior zones other than nipples?

I have come to realize that this was a stupid question. I apologize.

What I was referring to is the "tail of Spence" area. But it's only apparent when I woman is positioned a certain way. And I don't think it's part of the breast at all. It's just the soft flesh on her chest above each breast.

I appreciate the attempts to understand what the hell I was talking about.
