The glossopharyngeal nerve (cranial nerve IX) is responsible for a number of sensory and motor functions associated with the tongue (glossa in Greek) and the pharynx, or throat. In this video, I discuss the anatomy and function of the glossopharyngeal nerve, as well as what symptoms can appear when the nerve is damaged.
If you enjoy the content on this site, then you might also like my new book: Your Brain, Explained, which will be published in September by Nicholas Brealey Publishing. Your Brain, Explained is an introduction to neuroscience that can be understood by anyone, even those without any neuroscience background at all. The book is arranged into ten chapters that examine subjects like fear, sleep, pleasure, vision, etc. In those chapters I discuss a variety of individual brain regions like the amygdala, brainstem, reward system, hippocampus, and a long list of others, and explore how they work together to create the brain functions of our everyday lives. I also discuss what can go wrong to cause disorders like depression, ADHD, addiction, Alzheimer’s disease, and more. The official publication date is September 24, 2019, but if you’re interested please consider pre-ordering! To pre-order, click the button below!
