Viewing referential constraint

Is there any way to see/select/query referential constraints on tables? I have some constraints on a table that I did not create, and I want to see what rules were applied to them.

SQL Server has several stored procedures in the category of what is known as "catalog" procedures (because they give information regarding SQL Server's internal catalog) that will help you.

sp_help [table name] will provide a detailed description of a table including what indexes and constraints exist.
sp_pkeys and sp_fkeys provide information about primary and foreign keys respectively.
Sp_helptext [constraint name] will provide the SQL code of the constraint.
