The inspiration for this song, came from a young woman that presented to the ED with Bell's Palsy. It turns out that the facial nerve is responsible for a lot of functions, including motor function to the face, taste, and tears and salivation. The 7 faces in the crowd are drinking seven up, because the 7th cranial nerve, aka Facial nerve, is responsible for taste. Motor sensation includes muscles of facial expression.Parasympathetic functions include tears and salivation via petrosal nerve to pterygopalatine ganglion to lacrimal nerve.Taste via the lingual nerve, chorda tympani, solitary nucleus, thalamic VPM, to the gustatory taste center.
