Physiology of Articulation and Resonance

Vocabulary flashcards for speech anatomy and physiology.

Oral Resonance

Resonance produced with a closed VP port, as in the production of the /t/ and /b/ sounds in 'tube'.

Lingua-alveolar

Place of articulation involving the tongue and the alveolar ridge, as in the /t/ sound in 'tube'.

Stop-plosive

Manner of production where airflow is stopped and then suddenly released, as in /t/ and /b/.

Bilabial

Place of articulation involving both lips, like the /b/ sound.

Orbicularis Oris

Primary muscle responsible for labial seal.

Mentalis Muscle

Muscle that provides extra force for lip closure and wrinkles the chin.

Mandible

Lower jaw, moved by muscles of mastication.

Muscles of Mastication

Muscles used for chewing; mandibular elevators and depressors.

Extrinsic Lingual Muscles

Muscles that set the basic posture of the tongue (Hyoglossus, Styloglossus, Genioglossus).

Intrinsic Lingual Muscles

Muscles involved in smaller, more precise tongue movements (Superior longitudinal, inferior longitudinal, transverse, vertical).

Velum

Soft palate; elevated for non-nasal sounds.

Levator Veli Palatini

Muscle primarily responsible for elevation/retraction of the velum.

Tensor Veli Palatini

Muscle that opens the Eustachian Tube.

Musculus Uvulae

Muscle that bunches up when contracted, shortening the soft palate.
