Tongue Extrinsic Muscle Spasms

Tongue extrinsic muscle spasms, also known as lingual dystonia, are involuntary, often painful contractions of the muscles that move your tongue. These spasms can affect speech, swallowing, and overall comfort, making everyday tasks challenging. In simple terms, imagine your tongue twisting or jerking without warning—that’s a muscle spasm.

Anatomy of Extrinsic Tongue Muscles

The four extrinsic muscles of the tongue originate outside the tongue and insert into it. They move the tongue as a whole—protruding it forward, retracting it backward, raising or lowering parts of it, and enabling side‑to‑side motion EpainassistRadiopaedia.

Structure & Location

• Genioglossus

  • Shape & Location: Fan‑shaped, forming most of the tongue’s bulk.

  • Function: Protrudes (pushes forward) and depresses (pushes down) the tongue.

• Hyoglossus

  • Shape & Location: Thin, quadrilateral muscle at the tongue’s sides.

  • Function: Depresses (lowers) the sides of the tongue.

• Styloglossus

  • Shape & Location: Slender muscle running from the skull base to the tongue.

  • Function: Retracts (pulls back) and elevates the tongue.

• Palatoglossus

  • Shape & Location: Muscular arch between the soft palate and tongue.

  • Function: Elevates the back of the tongue and helps close off the throat during swallowing.

Origin & Insertion

Data from Kenhub and Quizlet KenhubQuizlet

Blood Supply

• Primary: Lingual artery (branch of the external carotid)

• Secondary: Sublingual branches to the tongue’s underside; ascending pharyngeal to palatoglossus KenhubCleveland Clinic

Nerve Supply

• Hypoglossal nerve (CN XII): Motor to genioglossus, hyoglossus, styloglossus

• Vagus nerve (CN X) via pharyngeal plexus: Motor to palatoglossus KenhubTeachMeAnatomy

Key Functions

1. Protrusion: Sticking the tongue out (genioglossus)

2. Retraction: Pulling the tongue back (styloglossus)

3. Elevation: Raising the back of the tongue for swallowing (palatoglossus)

4. Depression: Lowering the sides of the tongue (hyoglossus)

5. Shaping: Adjusting tongue shape for speech sounds (all extrinsics assist)

6. Side‑to‑Side Motion: Moving the tongue toward one corner of the mouth

   An involuntary contraction of one or more muscles that move the tongue as a whole.

2. How long do tongue spasms last?
   Often seconds to minutes; chronic cases may persist daily.

3. Is it dangerous?
   Rarely life‑threatening, but can impair swallowing and speech.

4. What triggers a spasm?
   Stress, medication changes, dehydration, or neurological issues.

5. Can tongue spasms resolve on their own?
