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]
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 produced from the same general area of the body involve the production of unvoiced consonants , clicks , whistling and whispering .)
The human supralaryngeal tract is said to be digital in the sense that it is an arrangement of moveable toggles or switches, each of which, at any one time, must be in one state or another. The vocal cords, for example, are either vibrating (producing a sound) or not vibrating (in silent mode).
Language is a core system that gives humans the capacity to solve difficult problems and provides them with a unique type of social interaction. [2] Language allows individuals to attribute symbols (e.g. words or signs) to specific concepts, and utilize them through sentences and phrases that follow proper grammatical rules . [ 2 ]
Human vocal apparatus used to produce speech. The physical structure of the human nose, throat, and vocal cords allows for the productions of many unique sounds, these areas can be further broken down into places of articulation. Different sounds are produced in different areas, and with different muscles and breathing techniques. [28]
It causes the voice to drop and deepen. Along with the larynx, the vocal folds (vocal cords) grow significantly longer and thicker. The facial bones begin to grow as well. Cavities in the sinuses, the nose, and the back of the throat grow bigger, thus creating more space within the head to allow the voice to resonate. [1]
The vibratory and viscoelastic characteristics of the human vocal cords are mainly attributed to the molecular composition of SLLPs. In normal vocal folds, the jelly-like "Reinke's space" is very loose and abundant with interstitial proteins such as hyaluronic acid , fibronectin, proteoglycan like fibromodulin, decorin and versican.
These earliest vocalizations include crying and vegetative sounds such as breathing, sucking or sneezing. For these vegetative sounds, infants’ vocal cords vibrate and air passes through their vocal apparatus, thus familiarizing infants with processes involved in later speech production.
