The larynx has two main functions: it acts‚ first‚ as a valve to protect the lungs and‚ second‚ as mechanism for producing sound. Describe how the larynx produces sound‚ including in your own words a description of the different anatomical parts and their interaction. The larynx is a vital part of the mechanism in our bodies that produces sound. It is basically made up of a series of cartilages‚ which also includes the thyroid or what would be an Adam’s apple on a male. As stated in the sentence

in the ambulatory suite for further examination of this lesion‚ using the operating microscope. After the administration of local anesthesia‚ a direct endoscope is introduced. The operating microscope is brought into the field‚ and the pharynx and larynx are visualized. The pharynx appears normal. There was a mass noted of the left vocal cord. The mass was approximately 2.0cm in size and was removed in total and sent to pathology for analysis. All secretions were suctioned‚ and the area was irrigated

4_Epiglottis Function (700 words) The epiglottis is located above the larynx. The function of the epiglottis is to protect the respiratory system from foreign particles‚ such as food. During swallowing‚ the epiglottis is depressed over the larynx. When breathing‚ it is open to allow air to travel freely. This article seeks to explain the function of the epiglottis and problems that may be associated with it. Epiglottis Function and Anatomy The epiglottis is formed by elastic cartilage and is

when the air is expelled from the lungs. In English‚ speech sounds are the result of “a pulmonic egressive air stream” (Giegerich‚ 1992) although that is not the case in all languages (ingressive sounds). The phonation process occurs at the larynx. The larynx has two horizontal folds of tissue in the passage of air; they are the vocal folds. The gap between these folds is called the glottis. English Phonetics and Phonology Fernando Trujillo The glottis can be closed‚ as in figure 1. Then‚ no

SYSTEMIC ANATOMY 1. Give OIAN of the tongue. The muscles of tongue can be divided into intrinsic and extrinsic groups. The intrinsic muscles lie entirely within the tongue‚ while the extrinsic muscles attach the tongue to other structures. The extrinsic muscles reposition the tongue‚ while the intrinsic muscles alter the shape of the tongue for talking and swallowing. Extrinsic tongue muscles‚ by definition‚ originate from structures outside the tongue and insert into the tongue. The four paired

LARYNGITIS The larynx‚ also known as the voice box‚ lies between the pharynx and the trachea. It has nine layers of cartilage and it contains two folds‚ called vocal cords. The opening between the vocal cords is called the glottis and as air leaves the lungs‚ the vocal cords vibrate and produce sound. The tongue and lips then act on the sound to produce speech. When the larynx and the vocal cords become inflamed or irritated‚ the condition is called Laryngitis. The swelling in the vocal cords causes

where food and air cross paths. The pharynx increases the chance of choking‚ but also allows breathing when exercising and respiration though the mouth‚ if the nose is closed. Next‚ epiglottis opens allowing air to move into the glottis‚ and pass the larynx (voice box). After this air makes its way into the trachea which cleans the air with cilia. The cilia move in the trachea and remove viruses‚ dust‚ or other unwanted material by trapping it in mucus. The mucus is than moved up the trachea into the
