The hyoglossus muscle ("hyoid bone-tongue muscle") is one of the outer muscles of the tongue , as it can move the tongue in different directions due to its origin on the hyoid bone ( corpus ossis hyoidei , cornu majus ossis hyoidei ). It radiates into the tongue in a fan shape and attaches to the aponeurosis linguae . In the case of bilateral contraction, it pulls the tongue backwards and downwards; in the case of one-sided contraction, it pulls it down and to the corresponding side.
In interaction with the other muscles, it is important for chewing , swallowing , speaking and sucking . The tongue muscles form the tongue sounds ( linguals ).
Varieties
Variable splits of the muscle on the hyoid bone are called the chondroglossus muscle .
