Vocal cord nodules are bilaterally symmetrical benign white masses that form at the midpoint of the vocal folds. [1] Although diagnosis involves a physical examination of the head and neck, as well as perceptual voice measures, visualization of the vocal nodules via laryngeal endoscopy remains the primary diagnostic method.
William Vennard (January 31, 1909 Normal, Illinois – January 10, 1971, Los Angeles, California) was a famous American vocal pedagogist who devoted his life to researching the human voice and its use in singing. He was one of the driving forces behind a major shift within the field of vocal pedagogy during the middle of the 20th century. [1]
The vocal folds are commonly referred to as vocal cords, and less commonly as vocal flaps or vocal bands. The term vocal cords was coined by the French anatomist Antoine Ferrein in 1741. In his violin analogy of the human voice, he postulated that the moving air acted like a bow on cordes vocales. [42]
Vocal registration refers to the system of vocal registers within the human voice. A register in the human voice is a particular series of tones, produced in the same vibratory pattern of the vocal folds , and possessing the same quality.
The vestibular fold (ventricular fold, superior or false vocal cord) is one of two thick folds of mucous membrane, each enclosing a narrow band of fibrous tissue, the vestibular ligament, which is attached in front to the angle of the thyroid cartilage immediately below the attachment of the epiglottis, and behind to the antero-lateral surface of the arytenoid cartilage, a short distance above ...
Straining the voice can lead the development of vocal nodules, a form of scarring on the vocal cords caused by strenuous or abusive voice practices. Professional singers on extended tours with tight schedules run a substantial risk of damaging their voices unless they make sure to rest the vocal cords and get enough sleep and proper diet.

Successful non-classical baritones display a wide range of vocal qualities and effects that lend a unique character to their voices, many of which are considered undesirable in the operatic or classical baritone singer, such as "breathy" , [3] "distinguished…crooner" , [4] "growling" (Neil Diamond), [5] and even "ragged" (Bruce Springsteen).
The intermediate and deep layers of lipopolysaccharides compose the vocal ligaments which are enclosed within the vocal folds and are responsible for strain in phonation. Within the extracellular matrix community of vocal ligament, fibrous proteins such as elastin and collagen are pivotal in maintaining the proper elastic biomechanical property ...
