Anatomy
The Laryngeal System is made up mostly of cartilage. The one bone it contains is called the
Hyoid Bone
As constriction decreases, laryngeal airway resistance will _____.
Decrease: The laryngeal airway is widened so there is less resistance.
An imaging tool that is similar to the flexible endoscopy but instead uses a light source to view the moving vocal folds.
Videostroboscopy
The thin layer that covers the vocal folds is called the
Epithelium
The joint of the larynx that is responsible for regulating fundamental frequency is ___.
Cricothyroid Joints: They stretch the vocal folds which influences a change in pitch of an individual's voice.
Why is it important to evaluate a person’s voice before starting voice therapy?
Assess the severity of the problem: This will help determine which exercises/testing would be most beneficial to that patient.
True or False: The Cricoarytenoid joints connect to the thyroid and allows the vocal folds to stretch
False
TRUE or FALSE: The false vocal folds are located above the true vocal folds and should remain open during phonation.
True: The false vocal folds should remain open during phonation and closed during swallowing.
Voice breaks, aperiodicity, erratic frequency shifts, and a high jitter and shimmer are all acoustic features of this disorder of the laryngeal system
Spasmodic Dysphonia
The Oblique Arytenoid, Transverse Arytenoid, and Lateral Cricoarytenoid all ______ the vocal folds
Adduct
How does the breathing apparatus influence sound pressure level (SPL)?
Due to changes in tracheal air pressure
TRUE or FALSE: Prolonged speech aims at having the individual use a slow rate and continuous vocalization across words and syllables.
True (Stuttering Exercise): Fluency inducing conditions use continuous vocalizations to reduce
stuttering.
These muscles have one point of attachment in the larynx and one point of attachment on the outside
The ________ theory discusses the connection between muscle force, elasticity of tissues, and air pressure in relation to creating voicing. This theory describes how vibration of the vocal folds is initiated and enforces that the vocal folds open and close from ____ to ____.
1.) Myo-elastic aerodynamic theory
2.) Bottom to top
Voice banking and preservation of the voice are all clinical characteristics of this laryngeal system disorder
Amyotrophic Lateral Sclerosis (ALS)
