1. Intrinsic Longitudinal Muscles

   Linked via "genioglossus"

   Role in Vowel Production
   While the extrinsic muscles (like the genioglossus) primarily control tongue position in the oral cavity, the intrinsic longitudinal muscles dictate the internal curvature and dorsopalatal contour. They are directly responsible for the 'tensing' aspect of vowel articulation.
   The precise antagonistic balance between the [longitudinal muscles](/en…

2. Tongue Body Position

   Linked via "genioglossus"

   Functional Anatomy and Nomenclature
   The tongue body is the largest component of the tongue musculature, primarily consisting of the intrinsic muscles (superior longitudinal, inferior longitudinal, vertical, and transverse) and extrinsic muscles (genioglossus, hyoglossus, styloglossus, and palatoglossus). Its position is conventionally described relative to the [palate](/…

3. Tongue Body Position

   Linked via "genioglossus"

   The Influence of Pharyngeal Constriction
   While traditionally analyzed in isolation within the oral cavity, modern articulatory phonetics emphasizes the role of the pharynx in shaping the resonating chamber, particularly for back vowels. Retraction of the tongue body invariably leads to increased pharyngeal constriction, mediated primarily by the genioglossus (posteri…

4. Tongue Dorsum

   Linked via "Genioglossus"

   Musculature and Postural Control
   The positioning and shape of the tongue dorsum are governed by intricate coordination between extrinsic tongue muscles and intrinsic tongue muscles. The extrinsic muscles(Genioglossus, Hyoglossus, Styloglossus, Palatoglossus) are responsible for gross displacement and [elevation/depression](/entri…
