Function of the tongue muscles

A list of the specific functions of the extrinsic and intrinsic muscles of the tongue and their effects on the body of the tongue (from Thiele et al. 1992). Without the stable but­tress formed by the musculature of the floor of the mouth, many dys­functions of the tongue would not be possible. The floor of the mouth is stabilized differently in different individuals. The act of swallowing does not necessarily involve all the muscles of the floor of the mouth in lifting the hyoid bone (Spiro et al. 1994).


Acting muscle Effect on the body of the tongue
Styloglossus muscle High position of the dorsum with tendency for widening; interocclusal position; lateral and palatal thrusting (unilateral and bilateral)
Genioglossus muscle Forward thrust of the medial portion; low position of the tip; frontal thrust
Hyoglossus muscle Low position of the body of the tongue; low, lateral tongue thrust
longitudinalis muscle Short, thick, wide ball shape
Transverse muscle of tongue Anterior thrust and interocclusal position
Vertical muscle of tongue Lateral thrust and interocclusal position
