How to get names of the table attributes?

I am working Sql Server 2005 My table name is Customer, the attributes are

Orderid Customerid Customeraddress

Wherein Customerid is the primary key and Orderid is the foreign key.

I want to know the primary key name, foreign key name and the table name where the foreign key exists as a primary key

Is there any query to retrieve those names using a table name? Kindly please provide me the queries...T开发者_JAVA技巧hanks in advance
