  • 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.

Delaney, DDS, MSD, and Martha Ann Keels, DDS, PhD Parents often are concerned with “lumps and bumps” that appear in the mouths of children. Pediatricians should be able to distinguish the normal clinical appearance of the intraoral tissues in children from gingivitis, periodontal abnormalities, and oral lesions. Recognizing early primary tooth mobility or early primary tooth loss is critical because these dental findings may be indicative of a severe underlying medical illness. Diagnostic criteria and .treatment recommendations are reviewed for many commonly encountered oral conditions. INTRAORAL SOFT-TISSUE ABNORMALITIES Congenital Lesions Ankyloglossia Ankyloglossia, or “tongue-tied,” is a common congenital condition characterized by an abnormally short lingual frenum and the inability to extend the tongue. The frenum may lengthen with growth to produce normal function. If the extent of the ankyloglossia is severe, speech may be affected, mandating speech therapy or surgical correction. If a child is able to extend his or her tongue sufficiently far to moisten the lower lip, then a frenectomy usually is not indicated (Fig. 1).

  • Part 1: Introduction to The
    PREVIEW OF THE IPA HANDBOOK Handbook of the International Phonetic Association: A guide to the use of the International Phonetic Alphabet PARTI Introduction to the IPA 1. What is the International Phonetic Alphabet? The aim of the International Phonetic Association is to promote the scientific study of phonetics and the various practical applications of that science. For both these it is necessary to have a consistent way of representing the sounds of language in written form. From its foundation in 1886 the Association has been concerned to develop a system of notation which would be convenient to use, but comprehensive enough to cope with the wide variety of sounds found in the languages of the world; and to encourage the use of thjs notation as widely as possible among those concerned with language. The system is generally known as the International Phonetic Alphabet. Both the Association and its Alphabet are widely referred to by the abbreviation IPA, but here 'IPA' will be used only for the Alphabet. The IPA is based on the Roman alphabet, which has the advantage of being widely familiar, but also includes letters and additional symbols from a variety of other sources. These additions are necessary because the variety of sounds in languages is much greater than the number of letters in the Roman alphabet. The use of sequences of phonetic symbols to represent speech is known as transcription. The IPA can be used for many different purposes. For instance, it can be used as a way to show pronunciation in a dictionary, to record a language in linguistic fieldwork, to form the basis of a writing system for a language, or to annotate acoustic and other displays in the analysis of speech.

  • Salivary Glands
    GASTROINTESTINAL SYSTEM [Anatomy and functions of salivary gland] 1 INTRODUCTION Digestive system is made up of gastrointestinal tract (GI tract) or alimentary canal and accessory organs, which help in the process of digestion and absorption. GI tract is a tubular structure extending from the mouth up to anus, with a length of about 30 feet. GI tract is formed by two types of organs: • Primary digestive organs. • Accessory digestive organs 2 Primary Digestive Organs: Primary digestive organs are the organs where actual digestion takes place. Primary digestive organs are: Mouth Pharynx Esophagus Stomach 3 Anatomy and functions of mouth: FUNCTIONAL ANATOMY OF MOUTH: Mouth is otherwise known as oral cavity or buccal cavity. It is formed by cheeks, lips and palate. It encloses the teeth, tongue and salivary glands. Mouth opens anteriorly to the exterior through lips and posteriorly through fauces into the pharynx. Digestive juice present in the mouth is saliva, which is secreted by the salivary glands. 4 ANATOMY OF MOUTH 5 FUNCTIONS OF MOUTH: Primary function of mouth is eating and it has few other important functions also. Functions of mouth include: Ingestion of food materials. Chewing the food and mixing it with saliva. Appreciation of taste of the food. Transfer of food (bolus) to the esophagus by swallowing . Role in speech . Social functions such as smiling and other expressions. 6 SALIVARY GLANDS: The saliva is secreted by three pairs of major (larger) salivary glands and some minor (small) salivary glands. Major glands are: 1. Parotid glands 2. Submaxillary or submandibular glands 3. Sublingual glands. 7 Parotid Glands: Parotid glands are the largest of all salivary glands, situated at the side of the face just below and in front of the ear.

  • Nasal Consonant the Basic Characteristic of a Nasal Consonant Is That the Air Escapes Through the Nose
    Nasal Consonant The basic characteristic of a nasal consonant is that the air escapes through the nose. For this to happen, the soft palate must be lowered; in the case of all the other consonants, and all vowels, the soft palate is raised and air cannot pass through the nose, in nasal consonants, hoever, the air does not pass through the mouth; it is prevented by a complete closure in the mouth at some point. /m/ and /n/ are simple , straightforward consonants with distributions like those of the plosives. There is in fact little to describe. However, /η/ is a different matter. It is a sound that gives considerable problems to foreign learners, and one that is so unusual in its phonological aspect that some people argue that it is not one of the phonemes of English at all. There are three phonemes in English which are represented by nasal consonants, /m/ , /n/ and /η/. In all nasal consonants the soft palate is lowered and at the same time the mouth passage blocked at some point, so that all the air pushed out of the nose. /m/ and /n/ All languages have consonants which are similar to / m/ and /n/ in English. Notice: 1- the soft palate is lowered for both /m/ and /n/. 2- for /m/ the mouth is blocked by closing the two lips, for /n/ by pressing the tip of the tongue against the alveolar ridge, and the sides of the tongue against the sides of the palate. 3- Both sounds are voice in English, as they are in other languages, and the voiced air passes out through the nose.

ISBN: 978-0-615-64912-2 Preface The surgical care of trauma to the face, head, and neck that is an integral part of the modern practice of otolaryngology–head and neck surgery has its origins in the early formation of the specialty over 100 years ago. Initially a combined specialty of eye, ear, nose, and throat (EENT), these early practitioners began to understand the inter-rela- tions between neurological, osseous, and vascular pathology due to traumatic injuries. It also was very helpful to be able to treat eye as well as facial and neck trauma at that time. Over the past century technological advances have revolutionized the diagnosis and treatment of trauma to the face, head, and neck—angio- graphy, operating microscope, sophisticated bone drills, endoscopy, safer anesthesia, engineered instrumentation, and reconstructive materials, to name a few. As a resident physician in this specialty, you are aided in the care of trauma patients by these advances, for which we owe a great deal to our colleagues who have preceded us. Additionally, it has only been in the last 30–40 years that the separation of ophthal- mology and otolaryngology has become complete, although there remains a strong tradition of clinical collegiality.

  • Appendix B: Muscles of the Speech Production Mechanism
    Appendix B: Muscles of the Speech Production Mechanism I. MUSCLES OF RESPIRATION A. MUSCLES OF INHALATION (muscles that enlarge the thoracic cavity) 1. Diaphragm Attachments: The diaphragm originates in a number of places: the lower tip of the sternum; the first 3 or 4 lumbar vertebrae and the lower borders and inner surfaces of the cartilages of ribs 7 - 12. All fibers insert into a central tendon (aponeurosis of the diaphragm). Function: Contraction of the diaphragm draws the central tendon down and forward, which enlarges the thoracic cavity vertically. It can also elevate to some extent the lower ribs. The diaphragm separates the thoracic and the abdominal cavities. 2. External Intercostals Attachments: The external intercostals run from the lip on the lower border of each rib inferiorly and medially to the upper border of the rib immediately below. Function: These muscles may have several functions. They serve to strengthen the thoracic wall so that it doesn't bulge between the ribs. They provide a checking action to counteract relaxation pressure. Because of the direction of attachment of their fibers, the external intercostals can raise the thoracic cage for inhalation. 3. Pectoralis Major Attachments: This muscle attaches on the anterior surface of the medial half of the clavicle, the sternum and costal cartilages 1-6 or 7. All fibers come together and insert at the greater tubercle of the humerus. Function: Pectoralis major is primarily an abductor of the arm. It can, however, serve as a supplemental (or compensatory) muscle of inhalation, raising the rib cage and sternum. (In other words, breathing by raising and lowering the arms!) It is mentioned here chiefly because it is encountered in the dissection.
