Genioglossus motion under ultrasound imaging

The genioglossus (GG) is the largest dilator of the upper airway and it  has been shown with ‘tagged’ MRI imaging to both depress and protrude the tongue during quiet breathing (Cheng et al 2008). Further understanding of the GG’s role in both healthy people and those with upper airway disorders can be aided by real-time imaging of the tongue’s motion.
