A palatoglossus muscle sprain (more accurately a strain) is an injury to the palatoglossus muscle, one of the extrinsic muscles of the tongue that also forms the anterior pillar of the soft palate. In a sprain/strain, the muscle fibers are overstretched or torn due to excessive mechanical stress—often from sudden forceful movements of the tongue or soft palate during swallowing, speaking, or oropharyngeal activities. This injury impairs the muscle’s ability to elevate the tongue root and depress the soft palate, leading to pain, swelling, and difficulty swallowing or speaking Wikipedia.
Anatomy of the Palatoglossus Muscle
Structure & Location
The palatoglossus is an extrinsic tongue muscle originating from the palatine aponeurosis of the soft palate and inserting into the side of the tongue, forming the palatoglossal arch (anterior pillar of fauces) on each side of the oropharynx TeachMeAnatomyNCBI.
Origin
Fibers arise from the superior surface of the palatine aponeurosis, interlacing with the contralateral muscle across the midline of the soft palate www.elsevier.com.
Insertion
The muscle runs anteroinferiorly, anterior to the palatine tonsil, fanning out to insert into the posterolateral aspect of the tongue, blending with intrinsic tongue fibers www.elsevier.com.
Blood Supply
Primarily supplied by branches of the lingual artery (a branch of the external carotid), with additional contribution from the tonsillar branch of the facial artery TeachMeAnatomy.
Nerve Supply
Uniquely, it is the only tongue muscle innervated by the pharyngeal branch of the vagus nerve (CN X) via the pharyngeal plexus; all other extrinsic tongue muscles receive fibers from the hypoglossal nerve (CN XII) TeachMeAnatomy.
Functions
-
Elevation of Tongue Root: Lifts the back of the tongue to aid in swallowing.
-
Depression of Soft Palate: Draws the soft palate downward to narrow the oropharyngeal isthmus.
-
Sealing Oral Cavity: Helps occlude the oral cavity during swallowing, preventing food or saliva escape.
-
Propulsion of Food Bolus: Works with other muscles to push a bolus toward the esophagus.
-
Speech Articulation: Assists in modifying the shape of the oral cavity for certain speech sounds.
-
Preventing Nasal Regurgitation: By coordinating palate and tongue, it prevents food from entering the nasal passages NCBI.
Types of Palatoglossus Muscle Sprain
Based on the Munich consensus classification for muscle injuries in sport:
-
Type 1a (Fatigue‑related Muscle Disorder): Overuse without fiber disruption PubMedBritish Journal of Sports Medicine.
-
