Sprain (strain) of the transverse muscle of the tongue—often called a “tongue muscle sprain”—occurs when the intrinsic fibers that narrow and elongate the tongue are overstretched or partially torn. Though true “sprains” classically refer to ligaments, in clinical practice muscle overuse or microtears in the transversus linguae present similarly: pain, swelling, and impaired tongue function.
Anatomy of the Transversus Linguae Muscle
Structure & Location
The transversus linguae is one of four intrinsic tongue muscles, located entirely within the tongue substance. It lies deep to the superior longitudinal muscle and superficial to the inferior longitudinal muscle, spanning from the midline septum laterally toward the tongue margins Wikipedia.
Origin
Fibers arise from the median fibrous septum—a vertical band of connective tissue dividing right and left halves of the tongue IMAIOS.
Insertion
Fibers fan out laterally to insert into the submucosal fibrous tissue along the tongue’s sides (dorsal and lateral margins) www.elsevier.com.
Blood Supply
Primarily from branches of the lingual artery, which arises from the external carotid artery and courses deep to the hyoglossus muscle before supplying all intrinsic lingual muscles NCBI.
Nerve Supply
Motor innervation by the hypoglossal nerve (cranial nerve XII), which supplies all intrinsic and most extrinsic tongue muscles except palatoglossus Wikipedia.
Key Functions
Elongation: Contracts to lengthen the tongue.
Narrowing: Pulls lateral fibers inward, making the tongue slimmer.
Shape Modulation: Helps form a blade-like tongue configuration for precise speech sounds.
Bolus Manipulation: Assists in shaping and directing food during chewing and swallowing.
Articulation Support: Works with other intrinsic muscles to refine consonant and vowel formation.
Postural Stability: Maintains tongue contour at rest, facilitating airway patency and resting posture.
Types of Transversus Linguae Sprain
Sprains (strains) of this muscle are classified by severity:
Grade I (Mild): Overstretching without fiber tear; minor pain, full range of motion.
Grade II (Moderate): Partial fiber tear; noticeable pain, mild swelling, limited tongue movement.
Grade III (Severe): Complete fiber rupture; severe pain, significant swelling/hematoma, marked loss of function.
Causes
Sudden Overstretching during wide tongue protrusion (e.g., during airway instrumentation).
