The human vocal cords are roughly 12 – 24 mm in length, and 3–5 mm thick. [9] Histologically, the human vocal cords are a laminated structure composed of five different layers. The vocalis muscle, main body of the vocal cords, is covered by the mucosa, which consists of the epithelium and the lamina propria. [10]
They are flat triangular bands and are pearly white in color. Above both sides of the vocal cord is the vestibular fold or false vocal cord, which has a small sac between its two folds. The difference in vocal fold size between men and women means that they have differently pitched voices.
The lower pair of folds are known as the vocal cords, which produce sounds needed for speech and other vocalizations. The slit-like space between the left and right vocal cords, called the rima glottidis, is the narrowest part of the larynx. The vocal cords and the rima glottidis are together designated as the glottis.
The process continues in a periodic cycle that is felt as a vibration (buzzing). In singing, the vibration frequency of the vocal folds determines the pitch of the sound produced. Voiced phonemes such as the pure vowels are, by definition, distinguished by the buzzing sound of this periodic oscillation of the vocal cords.
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 ...
The glottis is defined as the true vocal folds and the space between them. It is composed of an intermembranous portion or anterior glottis, and an intercartilaginous portion or posterior glottis. The border between the anterior and posterior glottises is defined by an imaginary line drawn across the vocal fold at the tip of the vocal process ...
A labeled anatomical diagram of the vocal folds or cords. a particular part of the vocal range such as the upper, middle, or lower registers; a resonance area such as chest voice or head voice; a phonatory process; a certain vocal timbre; a region of the voice defined or delimited by vocal breaks
Both boys and girls prior to puberty have an equivalent vocal range and timbre. The reason for this is that both groups have a similar larynx size and height and a similar vocal cord structure. With the onset of puberty, both men and women's voices alter as the vocal ligaments become more defined and the laryngeal cartilages harden. The ...
