Tongue muscle injuries are damage to the muscles of the tongue, which can affect speech, eating, swallowing, and overall oral health. Because the tongue plays a vital role in daily functions—like talking, tasting, and chewing—knowing about its anatomy, how injuries happen, and how to treat them is important.
A tongue muscle injury occurs when one or more of the muscles inside or around the tongue are strained, torn, bruised, or otherwise damaged. Injuries can range from mild strains (like a small bruise) to serious tears or nerve damage. Common names include tongue strain, tongue sprain, or tongue laceration.
Anatomy of the Tongue Muscles
Understanding tongue injuries starts with knowing the tongue’s muscles. There are four extrinsic muscles (attach tongue to structures) and four intrinsic muscles (shape the tongue itself). Below is a simplified breakdown.
Structure & Location
Extrinsic Muscles (move the tongue in the mouth)
Genioglossus – bulk of tongue, from chin to tongue body
Hyoglossus – side of tongue, from hyoid bone to tongue
Styloglossus – from the skull’s styloid process to side of tongue
Palatoglossus – from soft palate to tongue
Intrinsic Muscles (shape the tongue)
Superior longitudinal – upper layer, runs front to back
Inferior longitudinal – lower layer, runs front to back
Transverse – runs side to side
Vertical – runs top to bottom
Origin & Insertion
| Muscle | Origin | Insertion |
|---|---|---|
| Genioglossus | Mandible (chin) | Tongue body |
| Hyoglossus | Hyoid bone | Side of tongue |
| Styloglossus | Styloid process of temporal bone | Side/back of tongue |
| Palatoglossus | Soft palate | Side of tongue |
| Superior longitudinal | Tongue root and septum | Tongue tip and edges |
| Inferior longitudinal | Tongue root | Tongue tip |
| Transverse | Median septum of tongue | Sides of tongue |
| Vertical | Dorsal (top) tongue surface | Ventral (bottom) surface |
Blood Supply
Lingual artery (branch of external carotid) • Supplies most tongue muscles
Sublingual artery (branch of lingual) • Feeds underside tissues
Nerve Supply
Motor: Hypoglossal nerve (cranial nerve XII) activates all except palatoglossus
Motor (palatoglossus): Vagus nerve (cranial nerve X) via pharyngeal plexus
Sensory & Taste:
Anterior two-thirds: Lingual nerve (touch) & chorda tympani (taste)
Posterior one-third: Glossopharyngeal nerve (CN IX)
Main Functions
Speech Production – Shapes sounds into words
Chewing (Mastication) – Moves food between teeth
Swallowing (Deglutition) – Pushes food to throat
Taste Sensation – Houses taste buds for sweet, sour, salty, bitter, umami
Oral Hygiene – Clears debris from teeth and gums
Airway Protection – Helps close airway during swallowing
