Velocardiofacial Syndrome
An inherited disorder characterized by cleft palate (opening in the roof of the mouth), heart defects, characteristic facial appearance, minor learning problems, and speech and feeding problems.
Velopalatine Insufficiency
Failure of the palate to adequately block the connection between the mouth and nose so that the voice sounds vary nasal and fluid may enter the nose during swallowing.
Velum
The area in the back of the nose connecting it to the throat and breathing tube.
Vertigo
A false sensation of motion or spinning that leads to dizziness and discomfort. The illusion of movement; a sensation as if the external world were revolving around an individual (objective vertigo) or as if the individual were revolving in space (subjective vertigo).
Vestibular Neuronitis
An inflammation of the vestibular nerve.
Vestibular System
The system in the body that is responsible for maintaining balance, posture, and the body's orientation in space. This system also regulates locomotion and other movements and keeps objects in visual focus as the body moves.
Vestibule
The bony cavity of the inner ear.
Vibrotactile Aids
Mechanical instruments that help individuals who are deaf to detect and interpret sound through the sense of touch.
Vocal Cord Nodules
Small thickenings or "calluses" found on vocal cord which produce hoarseness by allowing air to escape through the vocal cords during speech.
Vocal Cord Paralysis
The inability of one or both vocal folds (vocal cords) to move because of damage to the brain or nerves. During speech this paralysis allows air to escape and decreases the quality of the voice.
Vocal Cords
Muscularized folds of mucous membrane that extend from the larynx (voice box) wall. The folds are enclosed in elastic vocal ligament and muscle that control the tension and rate of vibration of the cords as air passes through them.
Vocal Folds
Muscularized folds of mucous membrane that extend from the larynx (voice box) wall. The folds are enclosed in elastic vocal ligament and muscle that control the tension and rate of vibration of the cords as air passes through them.
Vocal Tremor
Trembling or shaking of one or more of the muscles of the larynx, resulting in an unsteady-sounding voice.
Voice
The sound produced by air passing out through the larynx and upper respiratory tract.
Voice Disorders
A group of problems involving abnormal pitch, loudness, or quality of the sound produced by the larynx (voice box).
