What is the dangling thing in the back of your throat called?

your uvula

Explanation:

the flesh that hangs in the back of your throat -- helps you swallow and speak. But you can run into problems if it's larger than normal. A swollen uvula can cause a sore throat, redness, trouble breathing or talking, or a choking feeling.
