Guys have this part on their body that I have heard referred to as v-lines.

Excuse me for not knowing much about anatomy but what exactly is it that creates the v-line look? Is it bone, or muscle, or maybe a combination? I have seen girls with a barely visible v-line. Even the girls who have nice define abs barely have v-lines.This is probably the most prominent v-line I've seen on a girl and her abs aren't even that defined.
