Research into Speech and Swallowing   Segmentation of Genioglossus, Styloglossus and inferior longitudinal muscles into Neuromuscular compartments. Genioglossus has 10 compartments consisting of a medial and lateral pair in each of 5 sectors.  
Biomechanical model demonstrating how one of 5 sectros of the tongue body may be controlled by contraction of Genioglossus neuromuscular compartment (NMC), Verticalis NMC and Transversus NMC Model of tongue sector control
