How much jaw volume is bone and how much is masseteer

[majstr]

Like after bloating my masseteers i look fine but when i try to shrink the jaw using my fingersi look like a pill jfl narrow head . Do people with good jawlines have them beacause of bone only or masseteers play a role too?

Mostly bone, muscle adds some definition esp with good insertion
