  • Comparative Anatomy of the Larynx and Related Structures
    Research and Reviews Comparative Anatomy of the Larynx and Related Structures JMAJ 54(4): 241–247, 2011 Hideto SAIGUSA*1 Abstract Vocal impairment is a problem specific to humans that is not seen in other mammals. However, the internal structure of the human larynx does not have any morphological characteristics peculiar to humans, even com- pared to mammals or primates. The unique morphological features of the human larynx lie not in the internal structure of the larynx, but in the fact that the larynx, hyoid bone, and lower jawbone move apart together and are interlocked via the muscles, while pulled into a vertical position from the cranium. This positional relationship was formed because humans stand upright on two legs, breathe through the diaphragm (particularly indrawn breath) stably and with efficiency, and masticate efficiently using the lower jaw, formed by membranous ossification (a characteristic of mammals).This enables the lower jaw to exert a pull on the larynx through the hyoid bone and move freely up and down as well as regulate exhalations. The ultimate example of this is the singing voice. This can be readily understood from the human growth period as well. At the same time, unstable standing posture, breathing problems, and problems with mandibular movement can lead to vocal impairment. Key words Comparative anatomy, Larynx, Standing upright, Respiration, Lower jawbone Introduction vocal cord’s mucous membranes to wave tends to have a morphology that closely resembles that of Animals other than humans also use a wide humans, but the interior of the thyroarytenoid range of vocal communication methods, such as muscles—i.e., the vocal cord muscles—tend to be the frog’s croaking, the bird’s chirping, the wolf’s poorly developed in animals that do not vocalize howling, and the whale’s calls.

  • Anatomy & Physiology of Speech
    ANATOMY & PHYSIOLOGY OF SPEECH The human body is highly adapted for speech. When we communicate using spoken language, we produce a wide range of sounds in a seemingly endless number of arrangements. So how do we go from streams of air to the sounds that make up words? Read on to find out! THE LUNGS, TRACHEA, AND DIAPHRAGM The words we speak start with air being exhaled from the lungs. During exhalation, the diaphragm and external intercostal muscles relax, causing air to leave the lungs. On its way out of the body, the air passes through the trachea, larynx, and pharynx before finally leaving through the oral or nasal cavity. DIAPHRAGM 2 EPIGLOTTIS HYOID BONE THE LARYNX The larynx is the uppermost airway of LARYNX the lower respiratory system. It sits on top of the trachea and is surrounded by a series of cartilages collectively referred to as the laryngeal skeleton. These cartilages are connected THYROID CARTILAGE by ligaments and moved by a variety of muscles. Though the airway remains open during breathing, the epiglottis closes off the entry to the larynx during swallowing in order to keep food and/or liquid from TRACHEA entering the trachea. 3 VESTIBULAR VOCALIS MANIPULATING FOLDS THYROARYTENOID VOCAL THE VOCAL FOLDS FOLDS The vocal folds (true vocal cords), stretch across the interior of the larynx. They enclose the vocal ligaments. Sound is produced when air coming up through the larynx causes the vocal folds to vibrate. This is called phonation. OBLIQUE The intrinsic muscles of the larynx alter ARYTENOID the quality and picth of the sound by manipulating the distance between and LATERAL tension of the vocal folds.

Screening is testing for cancer or pre-cancer in people who have no symptoms of the disease. Screening tests may find some types of cancer early, when treatment is most likely to be successful. For now, there is no screening test to find laryngeal and hypopharyngeal cancers early. These cancers are often hard to find and diagnose without complex tests. Because these cancers are not common, and the tests need specialized doctors, neither the American Cancer Society nor any other group recommends routine screening for these cancers. Sometimes though, laryngeal and hypopharyngeal cancers can be found early.
