  • How the Larynx (Voice Box) Works
    How the Larynx (Voice Box) Works Charles R. Larson, PhD If you love opera, or if you admire the voices of pop singers such as Celine Dion or Barbra Streisand, you may have wondered how it is these marvelous singers are able to create such beautiful music with this instrument we call the human voice. You may also know of someone who has a bad voice or has had to have their voice box, or larynx, removed because of illness or injury. The larynx is a critical organ of human speech and singing, and it serves important biological functions as well. Let's have a look at the larynx to understand its functions, what it looks like and how it works. It is thought that the same factors that favored the evolution of air‐breathing animals on earth led to the evolution of the larynx. Lungs are comprised of very delicate tissues that must be maintained within strict biological limits, that is, temperature, humidity and freedom from foreign particles. Thus, along with the first air‐breathing animals, there appeared a primitive sort of larynx, whose one and only function was protection of the lung. This function remains the most important of those the larynx has assumed in subsequent evolutionary developments. Now, of course we recognize that the larynx is critical for human speech and singing. But we also should realize that the larynx is important for swallowing, coughing, vomiting and eliminating contents of the abdomen. If you have ever felt your 'Adam's Apple', then you know where the larynx is.

  • Understanding Your Child's Videofluoroscopy
    Understanding your child’s videofluoroscopy swallow study report This leaflet will explain some of the words used by the speech and language therapist (SLT) in the letter sent out after the videofluoroscopy swallow study. The recommendations introduce some of the ways that your child’s problems with swallowing can be managed. If you have any questions or concerns, please speak to your SLT. What happens during swallowing? Swallowing is a series of movements that prepares food and fluid in the mouth, and then delivers it through the pharynx and oesophagus to the stomach. This is a diagram of the inside of the mouth and throat. You might find it useful to refer to when reading the information in this leaflet. 1 Tongue 2 Hard palate (roof of the mouth) 3 Soft palate (soft tissue at the back of the roof of the mouth) 4 Pharynx or throat (tube that connects the mouth and nostrils to the gullet) 5 Valeculae (depression below the root of the tongue) 6 Epiglottis (cartilage flap attached at the top of the larynx) 7 Pyriform sinuses (recesses on either side of the entrance to the larynx) 8 Larynx (the voice box, which is located at the top of the airway) 9 Vocal cords (two membranes which vibrate when speaking and move together when swallowing. This movement is a protective mechanism to stop food or drink entering the airway. The vocal cords are located in the voice box.) 10 Trachea (tube connecting the larynx to the lungs) 11 Upper oesophageal sphincter (muscular ring at the entrance to the oesophagus to reduce the risk of food coming back up) 12 Gullet or oesophagus (tube connecting the pharynx to the stomach) 1 of 3 Swallowing phases Swallowing involves three phases: 1.

  • PE3334 Difficulty Swallowing (Dysphagia)
    Difficulty Swallowing (Dysphagia) This handout talks about problems your child has in the throat (pharynx) when they swallow, how we diagnose it and how we treat it. What is dysphagia? Dysphagia means difficulty swallowing. Food and drink can get stuck (dis-FAY-je-ya) in the esophagus or “go down the wrong pipe” to the lungs (called aspiration) instead of the stomach. It can also go into the voice box but not all the way into the lungs (called penetration).

  • Exercise-Induced Laryngeal Obstruction
    American Thoracic Society PATIENT EDUCATION | INFORMATION SERIES Exercise-induced Laryngeal Obstruction Exercise-induced laryngeal obstruction (EILO) is a breathing problem that affects people during exercise. EILO is defined by inappropriate narrowing of the upper airway at the level of the vocal cords (glottis) and/or supraglottis (above the vocal cords). This can make it hard to get air into your lungs during exercise and cause a noisy breathing that can be frightening. EILO has also been called vocal cord dysfunction (VCD) or paradoxical vocal fold motion (PVFM). Most people with EILO only have symptoms when they Common signs and symptoms of EILO exercise, those some people may have the problem at During (or immediately after) high-intensity exercise, other times as well.
