vocal cords

Your vocal cords, or vocal folds, are two muscular bands inside your voice box that produce the sound of your voice. They also help you breathe and swallow food safely. You can damage your vocal cords if you're not careful.

The vocal folds, also known as the vocal cords / chords, are flaps of tissue located in the larynx. They give us the ability to produce sound (phonation). There are two folds, one on either side of the laryngeal cavity. Each fold is comprised of a vocal ligament, a vocalis muscle and a covering mucous membrane.

The vocal cord consists of two tight strings that open during breathing and close when you exhale to make a sound. They vibrate very fast, almost from 100 to 1000 times per second. You may vary the pitch, ‎which explains the concept of frequency, pitch, etc) by controlling the tension in the muscles in the voice box.

'Vocal cord' suggests a band or string suspended in the air that vibrates when it is plucked or struck. In fact, the vocal fold is a part of a muscle on the side of the larynx, covered with special tissues that can vibrate at a high speed. It resembles a lip of tissue much more than a cord.

Vocal cords are folds of tissue stretched within the larynx. Q. Assertion :Vocal cords consist of three pairs of mucous membrane that extend into the lumen of the larynx. Reason: Sound is produced by only two pairs of cords.

There are five different histologic types of vocal cord nodules: myxoid, fibrinous, vascular, fibrous, and mixed.

Kids Definition vocal cords. noun plural. : either of two pairs of elastic folds of tissue in the larynx of which the lower pair produce the voice when air exhaled from the lungs causes them to vibrate.

In humans sound is produced by the vioce box or larynx. It is the upper part of the wind pipe. Two vocal cords are stretched across the voice box leaving a narrow slit. When the lungs force air through the slit, it vibrates and produces sound.

The 'true vocal cords' are distinguished from the 'false vocal folds', known as vestibular folds or ventricular folds, which sit slightly superior to the more delicate true folds. These have a minimal role in normal phonation, but can produce deep sonorous tones, screams and growls.

The four main vocal ranges are:

• Soprano – A high female (or boy's) voice.
• Alto – A low female (or boy's) voice.
• Tenor – A high (adult) male voice.
• Bass – A low (adult) male voice.

The vocal folds are made of muscles covered by a thin layer called mucosa. There is a right and left fold, forming a "V" when viewed from above. At the rear portion of each vocal fold is a small structure made of cartilage called the arytenoid.

Briefly, the vocal folds are folds of tissue located in the larynx (voicebox) that have three important functions: To protect the airway from choking on material in the throat. To regulate the flow of air into our lungs. The production of sounds used for speech.
