Lisp level interaction questions



Hi all.  I have what are probably a couple silly questions:

Given a maxima object, is there a way to view the lisp level
composition of the object?  e.g:

lispstructure(a*b/(c*d));

Probably on a related note, if I define some objects in toplevel
Maxima:

a1 : a*b/(c*d);
b1 : [a,b,c,d,[e,f]];

and then enter into lisp via the to-lisp method:

 

How do I interact with a1 and b1 defined in Maxima?  What are they
named, for example?  How do I display their structure here?

Sorry if this should be obvious.
