COM Speech & Swallowing Disorders Flashcards

A patient presents with a tongue-thrust swallow pattern. Which muscle group typically shows hyperactivity in this pattern?

Answer: Perioral and mentalis muscles

In a tongue-thrust swallow, the perioral and mentalis muscles often contract excessively to stabilize the lip seal.

Which diagnostic tool is considered the gold standard for evaluating oropharyngeal swallowing function?

Answer: Videofluoroscopic swallow study (VFSS)

Videofluoroscopic swallow study (VFSS) provides real-time imaging of all swallowing phases and is considered the gold standard.

When a patient has reduced lingual strength, which compensatory strategy is most commonly observed during swallowing?

Answer: Increased head extension

Patients with reduced lingual strength often extend the head backward to use gravity to move the bolus posteriorly.

Which consonant class is most affected by inadequate tongue tip elevation and contact with the alveolar ridge?

Answer: Alveolar sounds /t/, /d/, /n/, /l/

Alveolar sounds require precise tongue tip elevation to contact the alveolar ridge, making them vulnerable to lingual dysfunction.

What is the recommended resting posture of the tongue for optimal orofacial development and speech?

Answer: Tongue tip at the incisive papilla, body gently touching the palate

The correct resting posture places the tongue tip at the incisive papilla with the body lightly contacting the palate, supporting arch development.

Which cranial nerve provides motor innervation to nearly all intrinsic and extrinsic tongue muscles?

Answer: Cranial Nerve XII (Hypoglossal)

Cranial Nerve XII (Hypoglossal) is the primary motor nerve for the tongue musculature.
