Anatomy and Physiology Tip The Pharnyx and Larynx In an effort to aid Health Information Management Coding Professionals with ICD-10 readiness, the following anatomy tip is provided with an educational intent. The pharynx Three Segments: a. The nasopharynx (epipharynx) extends from the base of the skull to the upper surface of the soft palate, ending at the uvula, which is the piece of tissue that hangs at the back of the throat. It provides a route for air to flow .separately from the route that food takes during the first steps of the digestive process. b. The oropharynx (mesopharynx) is the oral part of the pharynx that extends from the uvula to the hyphoid bone. It includes the soft palate, tonsils, and base of the tongue. The oropharynx plays a very important role in speech and swallowing. c. The laryngopharynx (hypopharynx) or throat is the part of the pharynx that connects to the esophagus. The larynx connects the pharynx to the trachea. Two Structures: a. The epiglottis, which is located just superior to the larynx is a flap-like structure that covers the opening of the larynx during swallowing. It prevents food and liquid from entering the trachea and harming the lungs. b. Vocal cords or voice box, which is located at the top of the trachea. It is composed of ligaments that vibrate to produce sound as air passes over them. The more air passes over them, the louder the sound that is produced. Change in pitch occurs through the use of small muscles that pull on the vocal cords. The vocal cords, along with the slit between them are known as the glottis. If food somehow gets past the epiglottis, the glottis will close to make sure food does not enter the trachea. References/Resources: 1. Okabe, Jerry M., et al.

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.

LINGUISTICS 330 Lecture #2 (Latin Dentes 'Teeth')
LINGUISTICS 330 Lecture #2 THE THREE PHYSIOLOGICAL COMPONENTS OF SPEECH PRODUCTION It is functionally appropriate to consider speech production in terms of three components: 1. THE SUBGLOTTAL SYSTEM: a. trachea (windpipe) b. lungs and associated respiratory muscles 2. LARYNX 3. SUPRALARYNGEAL VOCAL TRACT: Air passages above the larynx a. oral tract (= oral cavity) Latin os/oralis ‘mouth’ b. nasal tract (= nasal cavity) Latin nasus ‘nose’ c. pharynx (= pharyngeal cavity) Greek pharynx ‘throat’ SUPRAGLOTTAL ORGANS THE LIPS (prefix: labio-; suffix -labial) (Latin labia ’lip’ ) • The lips are a complex of muscles and other tissues (see below!) • The lips have a great capacity for varied movement, and much of their range of movement is utilized in speech (e.g. lip spreading, lip rounding, lip closing, etc.) THE TEETH (suffix: -dental) (Latin dentes ’teeth’) • They are set into the alveolar processes of the upper jaw (=maxillary bone) and the lower jaw (= mandible). (Alveolar processes: The inferior border of the maxillary bone or the superior border of the mandible; both contain sockets holding the teeth). 1 • The sides of the tongue pressed against the molars help to direct the air stream towards the front of the mouth, as in [ß] and [Ω]. • The lower lip approximates the maxillary incisors to constrict the air stream for [f] and [v]. • The tongue tip approximates the maxillary incisors for the production of [†] and [∂]. • The slightly opened maxillary and mandibular incisors provide friction surfaces for [s], [z], [ß] and [Ω]. THE TONGUE (suffix: -lingual) (Latin lingua ‘tongue’) • The floor of the oral cavity is largely formed by the three-dimensional muscle mass: the tongue.

Head and Neck
DEFINITION OF ANATOMIC SITES WITHIN THE HEAD AND NECK adapted from the Summary Staging Guide 1977 published by the SEER Program, and the AJCC Cancer Staging Manual Fifth Edition published by the American Joint Committee on Cancer Staging. Note: Not all sites in the lip, oral cavity, pharynx and salivary glands are listed below. All sites to which a Summary Stage scheme applies are listed at the begining of the scheme. ORAL CAVITY AND ORAL PHARYNX (in ICD-O-3 sequence) The oral cavity extends from the skin-vermilion junction of the lips to the junction of the hard and soft palate above and to the line of circumvallate papillae below. The oral pharynx (oropharynx) is that portion of the continuity of the pharynx extending from the plane of the inferior surface of the soft palate to the plane of the superior surface of the hyoid bone (or floor of the vallecula) and includes the base of tongue, inferior surface of the soft palate and the uvula, the anterior and posterior tonsillar pillars, the glossotonsillar sulci, the pharyngeal tonsils, and the lateral and posterior walls. The oral cavity and oral pharynx are divided into the following specific areas: LIPS (C00._; vermilion surface, mucosal lip, labial mucosa) upper and lower, form the upper and lower anterior wall of the oral cavity. They consist of an exposed surface of modified epider- mis beginning at the junction of the vermilion border with the skin and including only the vermilion surface or that portion of the lip that comes into contact with the opposing lip.
