COMD 4250 – Study Guide 5: Articulation

Flashcards covering key vocabulary and concepts from the Articulation lecture notes.

Articulation

Involves the modification of airflow and phonatory vibration to achieve different speech sounds.

Cranial Bones (Unpaired)

Occipital, Frontal, Sphenoid

Cranial Bones (Paired)

Temporals, Parietals

Facial Bones (Paired)

Maxillae, Zygomatic, Nasal, Palatine, Lacrimal, Mandible

Maxillae

Forms the upper jaw and part of the hard palate.

Zygomatic

Also known as cheekbones; articulate with the maxillae, temporal, and frontal bones and form the zygomatic arch.

Nasal Bones

Form the bridge of the nose.

Palatine Bones

Form the posterior part of the hard palate and part of the orbits.

Lacrimal Bones

Smallest bones of the face; located on the lateral part of the upper nose.

Mandible

The lower jawbone; the only movable bone of the face.

Hyoid Bone

Not technically a facial bone but located in the neck; supports the tongue and is involved in swallowing.

Nasal Cavity

Bordered inferiorly by the hard palate, superiorly and posteriorly by the sphenoid, and anteriorly by the nasal bones and septal cartilage.

Nasal Conchae

Wave-like structures within the nasal cavity that maximize surface area.

Oral Cavity

Bordered superiorly by the hard palate and the velum, inferiorly by the tongue, anteriorly by the lips, and posteriorly by the oropharynx; location of chewing and much articulation.

Faucial pillars

Muscles lining the posterior lateral edges of the oral cavity; form the border between oral and pharyngeal cavities.

Pharyngeal Cavity (Pharynx)

Divided into nasopharynx, oropharynx, and hypopharynx; contains pharyngeal constrictors.

Mobile Articulators

Lips, teeth, tongue, (glottis)

Immobile Articulators

Hard palate, alveolar ridge, velum

Orbicularis Oris

Orofacial muscle in an orbis around the mouth; reference orofacial muscle.

Levator Anguli Oris

Vertical orofacial muscle that lifts corners of mouth.

Depressor Anguli Oris

Vertical orofacial muscle that pulls corners of mouth down.

Mentalis

Vertical orofacial muscle that elevates chin.

Risorius

Transverse orofacial muscle that pulls mouth sideways.

Buccinator

Transverse orofacial muscle that pulls cheeks inwards & stabilizes them.

Zygomatic major

Angular orofacial muscle that elevates and retracts angle of mouth.

Mandibular Elevators

Mandibular temporalis, Mandibular masseter, Internal/medial pterygoid

Mandibular Depressors

Anterior digastric, Mylohyoid, Geniohyoid, External/lateral pterygoid

Intrinsic Tongue Muscles

Longitudinal (superior & inferior), Vertical, Transverse

Extrinsic Tongue Muscles

Palatoglossus, Styloglossus, Hyoglossus, Genioglossus

Velar Muscles

Levator veli palatini, Uvular muscle, Tensor veli palatini, Palatoglossus, Palatopharyngeus

Pharyngeal Constrictors

Superior, Middle, Inferior

Resonance

Filtering of vocal sound.

Velopharyngeal Port (VP)

The opening between the velum and the pharynx; regulates connection between nasal cavity and oral/pharyngeal cavities.

Consonant Production Parameters

Voicing, Place, Manner

Labial Sounds

Sounds involving one or more lips.

Dental Sounds

Linguadental (tongue tip placed between teeth), and labiodental (upper teeth compressed onto lower lip).

Alveolar Sounds

Sounds made at the alveolar ridge.

Vowels

Tongue shape and degree of mouth opening determine sound; do not involve obstruction of the oral/nasal cavities.
