FEDERAL RESERVE BANK: One of 37 Banks (12 District and 25 Branch) that comprise the Federal Reserve System. These Banks are largely responsible for supervising, regulating, and interacting with commercial banks and carrying out the policies established by the Federal Reserve Board of Governors. The large number of banks, spread across the country is what helps make the Federal Reserve System a very decentralized central bank.
