Action: When the mandible is fixed, they elevate the floor of the mouth and hyoid bone during the first stage of swallowing, When the hyoid bone is fixed, it assists in the depression of the mandible and the opening of the mouth. 3. Geniohyoid muscle: Origin: It ta...
Learn about the levator ani functions and innervation. Learn the three levator muscles, such as the iliococcygeus muscle, that make up the levator...
The principal focus of the study was the characterization of genioglossus muscle activation during SNIP and RSNEPmanoeuvres, primarilymotivated by the observation of reduced SNIPmax inmotor neuron patientswith bulbar involvement comparedwith non-bulbar disease (Chaudri, Liu,Watson, Jefferson, & Kinnear...

In particular, tongue muscles, subdivided into intrinsic (longitudinal, transversal and vertical) and extrinsic (hypoglossus, styloglossus, geniohyloid and genioglossus) ones, are exclusively innervated by the axons originating from the hypoglossal nucleus (XII cranial nucleus located in the medulla ...
Geniohyoid originates at the inferior mental spine of the mandible. The slender muscle continues inferiorly to insert on the anterior surface of the body of the hyoid bone. The bilaterally paired muscle lies between mylohyoid and genioglossus (base of the tongue). C1 fibers of the hypoglossal...
In the decerebrate cat, OX-A application into the hypoglos- sal motor nucleus increases genioglossus muscle activity (Peever et al., 2003). The pp-OX knockout mouse with a complete lack of orexin has normal resting breathing but a significantly attenu- ated respiratory chemorefle...

Through the muscle attachments, the hyoid plays an important role in mastication, in swallowing, and in voice production. At the beginning of a swallowing motion, the geniohyoid and mylohyoid muscles elevate the bone and the floor of the mouth simultaneously. These muscles are assisted by the ...
