Buccinator muscle the cheek area, which aids in holding the cheek to the teeth during chewing. This action causes the muscle to keep food pushed back on the occlusal surface of the posterior teeth, as when a person chews. By keeping the food in the correct position when chewing, the buccinator assists the muscles of mastication. It aids whistling and smiling, and in neonates it is used to suckle. In the past the buccinator muscle was also written as bucinator muscle. A "bucinator" in classical Latin is a trumpeter, or more precisely, the person who blows the "bucina". The name "bucina" could
Effect of spaceflight on the human body to best counteract the bone and muscle atrophy experienced by astronauts in microgravity environments for prolonged periods of time. The Human Research Program's Human Health Countermeasures Element chartered the Digital Astronaut Project to investigate targeted questions about exercise countermeasure regimes. NASA is focusing on integrating a model of the advanced Resistive Exercise Device (ARED) currently on board the International Space Station with OpenSim musculoskeletal models of humans exercising with the device. The goal of this work is to use inverse dynamics to estimate joint torques and muscle forces resulting from using the ARED, and thus more accurately prescribe exercise regimens
