The Judicial Branch, which is lead by the US Supreme Court, checks the power of the Legislative Branch through the use of what is called Judicial Review. This allows the Judicial Branch to decide if a law that Congress passed is constitutional or unconstitutional. Further, it allows the Judicial Branch to "define" that law by answering questions about it that are not spoken to directly in the regulation itself.
This power is not unlimited, however. No court can consider the constitutionality of a law unless the law is a relevant part of a "case or controversy" before the court.
Chief Justice John Marshall clearly affirmed the Court's right of judicial review in the case Marbury v. Madison, (1803), when the Court declared Section 13 of the Judicial Act of 1789 unconstitutional.
How the Legislative Branch checks the Judicial Branch
The Legislative branch checks the power of the Judicial branch by proposing amendments to overturn court decisions, creating lower courts, impeaching and removing justices, and rejecting appointments.
A Legislative 'check' against the Judicial Branch is that Federal Judges are confirmed (become seated Judges) by the Senate. Another is not exactly a check but, if the Federal Courts strike-down a law (invalidate it by finding that it is not Constitutional) Congress can recreate and pass a similar law. They just have to fix whatever problems the Federal Courts found with the previous law. I think that another check is that if a Federal Judge is to be impeached, the House of Representatives drafts and approves the articles of impeachment (the charges or grounds for impeachment) and the Senate hears the impeachment trial and rules on the articles of impeachment.
Some Legislative checks on the Executive Branch are that Congress approves funding for all Federal expenditures, so they approve the budgets for all the Executive agencies and departments, and funds any Presidential initiatives. The Senate also confirms Presidential nominations and appointments, such as Cabinet Department heads. Congress also must approve many Presidental acts, like declarations of war. Another is that if the President vetoes, or doesn't sign, a bill passed by Congress, Congress can override the veto by a super-majority vote (I think 2/3rds majority vote).
