Extracting terms from an equation

Greetings,

I'd like to find a general way to extract all of the terms from an
equation that involve a given variable. For instance, consider the
equation

myEquation == Exp[a + b x^2 + c y^2 + d x y + e x^3]]

I'd like to define a function such that

   myFunction[myEquation,x] returns the result {b x^2, d x y, e x^3}

Thanks,

-Mark
