Since frena/frenula are found in various interesting parts of the body :-) we do need to be correct and specify which frenum/frenulum we are talking about :-) (ie: fenulum linguae). I think the distinction may come from what the frenum/frenulum made of. Frenulum is a small fold of white matter and frenula is a fold of mucus membrane which conects 2 parts, one more or less moveable and serves to check movement. Also size may be a factor in use, fenulum-small bridle and fenum-bridle) SYN. is vinculum - a dividing band or bundle. And why are we discussing this??? :-) Because we want others to understand us ???
