The vocal folds, also known commonly as vocal cords or voice reeds, are composed of twin infoldings of mucous membrane stretched horizontally, from back to front, across the larynx. They vibrate, modulating the flow of air being expelled from the lungs during phonation.
Open when breathing and vibrating for speech or singing, the folds are controlled via the vagus nerve.
The vocal folds are located within the larynx at the top of the trachea. They are attached posteriorly to the arytenoid cartilages, and anteriorly to the thyroid cartilage. They are part of the glottis which includes the rima glottidis. Their outer edges are attached to muscle in the larynx while their inner edges, or margins are free, forming the opening called the rima glottidis. They are constructed from epithelium, but they have a few muscle fibres in them, namely the vocalis muscle which tightens the front part of the ligament near to the thyroid cartilage. They are flat triangular bands and are pearly white in color. Above both sides of the glottis are the two vestibular folds or false vocal folds which have a small sac between them.
The human voice consists of sound made by a human being using the vocal folds for talking, singing, laughing, crying, screaming etc. The human voice is specifically a part of human sound production in which the vocal folds (vocal cords) are the primary sound source. Generally speaking, the mechanism for generating the human voice can be subdivided into three parts; the lungs, the vocal folds within the larynx, and the articulators. The lung (the pump) must produce adequate airflow and air pressure to vibrate vocal folds (this air pressure is the fuel of the voice). The vocal folds (vocal cords) are a vibrating valve that chops up the airflow from the lungs into audible pulses that form the laryngeal sound source. The muscles of the larynx adjust the length and tension of the vocal folds to ‘fine-tune’ pitch and tone. The articulators (the parts of the vocal tract above the larynx consisting of tongue, palate, cheek, lips, etc.) articulate and filter the sound emanating from the larynx and to some degree can interact with the laryngeal airflow to strengthen it or weaken it as a sound source.
Miriam van Mersbergen, Ph.D., CCC-SLP, Assistant Professor at Northern Illinois University, and a professionally trained singer, speaks with John Consalvi, MA, CCC-SLP, and CEO/Founder of LinguaHealth, about the vocal cords. Miriam shares a video of her vocal cords in action, and discusses how the structures and movement of the cords affect the pitch and quality of the voice.

http://www.anatomyzone.com 3D anatomy tutorial on the membranes, ligaments and vocal cords using the BioDigital Human (http://www.biodigitalhuman.com). In this tutorial I talk about extrinsic and intrinsic ligaments of the larynx, and describe the relationship of the mucosal folds with these ligaments to form the vocal cords. Please watch the tutorial on the cartilages of the larynx before watching this one, as it will help if you are not familiar with the various structures!

http://www.powertosing.com/ I hope you don’t get queasy. I’m going to show you live video of a singer’s vocal cords as she sings. You may want to sit down. Many students feel singing is a great mystery. They don’t understand how their voice works, why it works the way it does, and what’s involved with singing. Vocal Cords It all begins with the vocal cords. Specialists look at your vocal cords with a flexible or rigid scope. The flexible scope is a small cord with a camera at the end of it. It’s inserted through the nose and extended down the throat to see the vocal cords. The rigid scope is like a large pen with a camera at the end. It’s used looking into the mouth and throat. Both images look like this. This can be confusing because the vocal cords are horizontal in the throat ...

The Voice Foundation Video Archives - In this didactic lecture, Dr. Sataloff presents an in-depth look at the advancement of phonosurgery from the days of vocal fold “stripping” to the present age of delicate microsurgery. He describes the anatomy and physiology of the vocal folds; the prerequisites for determining potential surgical candidates; techniques of vocal fold surgery; the importance of excellent anesthesiology, surgical instruments and laryngoscopes; the advantages/ disadvantages of the use of the carbon dioxide laser; vocal fold lesions which require surgery; and a comparison of microflap versus miniflap surgery. Dr. Sataloff continues with a discussion of surgical techniques for dissection of vocal fold masses (cysts), Reinke’s edema, excision of papillomas, surgery for carcin...

Tibetan Meditation: Enlightenment (120 minutes) 西藏 冥想: 啟蒙 (120 minutes) Tibetan Buddhist chanting is a subgenre of throat singing, mainly practiced by monks of Tibet, including Qinghai (Khokhonor) province Tibetan plateau area, Tibetan monks of Nepal, Bhutan, India and various locations in the Himalayan region. Most often the chants hold to the lower pitches possible in throat singing. Various ceremonies and prayers call for throat singing in Tibetan Buddhism, often with more than one monk chanting at a time. There are different Tibetan throat singing styles, such as Gyuke (Tibetan: རྒྱུད་སྐད་, Wylie: rgyud skad) - style with the lowest pitch of voice; Dzoke (Tibetan: མཛོད་སྐད་, Wylie: mdzod skad) and Gyer (Tibetan: གྱེར་, Wylie: gyer). Overtone singing is also known as overtone chanting,...
