Anatomy
The cartilage ring that forms the base of the larynx.
Cricoid Cartilage
The type of vocal fold movement that causes the termination of phonation.
Abduction of the vocal folds
This muscle is responsible for pitch control.
Cricothyroid
This muscle pulls the larynx downward after swallowing.
Sternothyroid
The psychological correlate for frequency is _________.
Pitch
The anterior projection of the thyroid cartilage where the two laminae are joined together.
Laryngeal Prominence
The type of voice that results from insufficient approximation of the vocal folds.
Breathy
This muscle attaches to the cricoid cartilage and adducts the vocal folds.
Lateral Cricoarytenoid (LCA)
These muscles function together to elevate the hyoid bone and depress the mandible.
Digastricus (Anterior & Posterior Bellies)
During quiet inspiration, the vocal folds are _________.
Abducted
These paired structures sit directly atop the apex of the arytenoid cartilages.
Corniculate Cartilages
Questions have a __________ intonation.
Rising
This muscle is responsible for the abduction of the vocal folds.
Posterior Cricoarytenoid (PCA)
Contraction of this muscle draws the hyoid bone superiorly and posteriorly.
Stylohyoid
This describes the relationship between velocity and air pressure - stating that as velocity increases, pressure decreases.
Bernoulli Principle
The connective tissue that connects the inferior border of the cricoid cartilage to the superior border of the first tracheal cartilage ring.
Cricotracheal Ligament
__________ pitch is considered to be the most efficient/appropriate for a person's vocal folds.
Optimal Pitch
This intrinsic laryngeal muscle adducts the vocal folds and helps close the posterior portion of the glottis during phonation.
Transverse Arytenoid
This muscle elevates the hyoid bone.
Genioglossus
Subglottic driving pressure for speech is measured in ______.
cm H2O
The opening between the two true vocal folds within the larynx that can change shape depending on what you are doing.
Rima Glottidis
The name for cycle by cycle variation in fundamental frequency of vibration - commonly called jitter.
Frequency Perturbation
This muscle is responsible for tensing the vocal folds.
Thyrovocalis
This muscle elevates/depresses the tongue and is important during speech and swallowing.
Hyoglossus
During phonation, the vocal folds open __________ to _____________.
Inferior to Superior
