Articulation and Resonance Anatomy Review

This set of flashcards covers key anatomical terminology and functions related to articulation and resonance.

Articulation

The process of producing sounds by using the articulators.

Articulators

Structures, both mobile and immobile, that shape the sounds of speech.

Source-filter theory

A model describing how the vocal tract shapes sound produced by the vocal cords.

Temporomandibular joint (TMJ)

The joint connecting the mandible to the skull, allowing for movement.

Velopharyngeal closure

The action that prevents air from escaping through the nasal cavity during speech.

Mucous membrane

A membrane that lines certain cavities in the body and secretes mucus.

Intrinsic tongue muscles

Muscles entirely contained within the tongue, allowing shape changes.

Extrinsic tongue muscles

Muscles that originate outside the tongue and insert into it, controlling its position.

Deciduous teeth

Temporary teeth that eventually fall out to be replaced by permanent teeth.

Malocclusion

Misalignment of teeth when the jaws are closed.

Pharynx

The part of the throat behind the mouth and nasal cavity, important for speech.

Facial nerve (VII)

The cranial nerve responsible for innervating the muscles of the lips.

Trigeminal nerve (V)

The cranial nerve responsible for innervating the muscles of the mandible.

Vagus nerve (X)

The cranial nerve involved in the control of the muscles of the pharynx and velum.

Sutures

Joints between bones of the skull that allow for slight movement.
