CSD 205: Anatomy, Physiology, and Science of Speech

A series of flashcards covering key concepts from the lecture on articulatory structures and resonance in speech.

Source-Filter Theory

A theory that describes how speech sounds are produced through the combination of an acoustic source, a filter (vocal tract shaping), and power (airflow from lungs).

Mandible

The strongest and largest facial bone, also known as the lower jaw.

Maxillae

The facial bone that forms the hard palate and is implicated in cleft palate.

Zygomatic Bone

The facial bone that makes up the cheekbone.

Nasal Conchae

Small, scroll-like bones that help warm, humidify, and filter air, comprising the middle and superior nasal conchae of the ethmoid bone.

Frontal, Temporal, Occipital, Parietal

The four cranial bones that share names with the lobes of the brain.

Sphenoid and Ethmoid

The two cranial bones that do not share names with brain lobes.

Sinus System

Spaces in the skull that aid in airflow, drainage, and protection.

Incisors, Cuspids, Bicuspids, Molars

The four categories of teeth.

Resonating Cavities of Vocal Tract

The four cavities are the oral, buccal, pharyngeal, and nasal cavities.

Pharynx

A 12cm tube lined with muscles extending from the vocal folds to the nasal cavity, divided into three regions: nasopharynx, oropharynx, and laryngopharynx.

Masseter, Temporalis, Medial Pterygoid

The three jaw muscles used in speech and chewing.

Intrinsic Tongue Muscles

Muscles located entirely within the tongue, enabling changes in its shape.

Extrinsic Tongue Muscles

Muscles outside the tongue that connect it to other structures, aiding in its movement.
