What Is the Dangly Thing at Back of Throat? That dangly thing at the back of your throat is the uvula or the palatine uvula. It is a conic project located in the middle of the soft palate at the back of your throat. This dangly structure is composed of several connective tissue and has several racemose glands as well as muscular fibers.
The uvula is part of the soft palate and is made of muscles and secretory organs. One anatomist has posted pictures showing how he can control his uvula as a party trick. Touching the uvula results in a gag reflex. I didn't test my own because I gag if anything pokes around near the back of my tongue.
