Analyze rule body in different rule

I need to be able to access the body of a rule in a different rule. For example, in the following, I want to be able to use the facts of rule in myRule when I call myRule(rule).

rule :-
    fact1(...),
    fact2(...),
    fact3(...).


myRule(RuleName) :-
    RuleName :- (F1, F2, F3),
    write(F1).

Obviously the above code does not work, and I have no idea of how to go about this, so I am asking for tips or anything to get me going in the right direction.

Please note that I am very new to Prolog and to logic programming in general. I'm having a hard time finding answers since I am not sure what exactly to look for.
