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 ...
Vocal folds (speaking) In humans, the vocal cords, also known as vocal folds, are folds of throat tissues that are key in creating sounds through vocalization. The length of the vocal cords affects the pitch of voice, similar to a violin string. Open when breathing and vibrating for speech or singing, the folds are controlled via the recurrent ...
The human voice consists of sound made by a human being using the vocal tract, including talking, singing, laughing, crying, screaming, shouting, humming or yelling. The human voice frequency is specifically a part of human sound production in which the vocal folds (vocal cords) are the primary sound source. (Other sound production mechanisms ...
The histological structure of the vocal fold can be separated into 5 [2] or 6 [3] tissues, depending on the source, which can then be grouped into three sections as the cover, the transition, and the body. The cover is composed of the epithelium (mucosa), basal lamina (or basement membrane zone), and the superficial layer of the lamina propria.
A vocal register is a range of tones in the human voice produced by a particular vibratory pattern of the vocal folds. These registers include modal voice (or normal voice), vocal fry, falsetto, and the whistle register. [1][2][3] Registers originate in laryngeal function. They occur because the vocal folds are capable of producing several ...
The cricothyroid muscle produces tension and elongation of the vocal cords. [ 3 ] [ 5 ] They draw up the arch of the cricoid cartilage and tilt back the upper border of the cricoid cartilage lamina. [ 3 ] [ 5 ] The distance between the vocal processes and the angle of the thyroid is increased, elongating [ 3 ] and thus tensing the vocal folds ...
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.
Vocal process. In the human larynx, the vocal process is the anterior angle of the base of the arytenoid cartilage, as it projects horizontally forward and gives attachment to the vocal ligament. The arytenoids are paired cartilages with a medial and a lateral process each. The medial process is called the vocal process because it is the ...
