Just to confirm:
Although the details of all database objects are stored in the system table MSysObjects, the fields are stored as table properties.
They aren't in any of the deep hidden tables, all of which I have viewed. Those are used to hold details of complex data stored in MVF, attachment and column history fields
I would suggest looking at Allen Browne's procedure to extract the field names, save them to a table and run a query on them as already suggested
See http://allenbrowne.com/func-DAO.html#ShowFields
Alternatively use the Database Documenter built in to Access to view a list of fields, datatypes etc.
The problem is that it gives far too much info and is only available as a report in print preview mode

Unfortunately you can't get to design view to view the report record source and query it. However you can export to e.g. Excel
