Introduction:
The larynx is a part of the upper respiratory tract and is found in the anterior part of the neck. It is commonly known as the voice box. Its main function is to prevent the food reaching the airway pathway. The larynx has nine cartilages that include three paired and three unpaired cartilages. A cartilage is a connective tissue that forms the structural component of the human body. It is a soft, smooth and elastic tissue and is found in the nose and bronchial tubes. The unpaired cartilages are the cricoid, epiglottis, and thyroid cartilages. The paired cartilages are arytenoid, corniculate, and cuneiform cartilages.

- 1)What is the anatomical reason that you are unable to breathe for a limited period of time once you swallow? How does this help to protect the lungs? 2)Polio causes a patient's intercostal muscles to be completely paralysed. What impact would this have on the patient's breathing?arrow_forwardA person was rushed into an emergency room after receiving a knife wound in the left side of his thorax. The diagnosis was pneumothorax and a collapsed lung. Why did the lung collapse, and why only one lung (not both) collapsed.arrow_forwardAs mentioned in the chapter, sometimes it is necessary to install a permanent tracheostomy—for example, in smokers who develop laryngeal cancer. Besides interfering with the ability to speak, what sorts of health problems would you expect to see in an individual with a permanent tracheostomy, and why?arrow_forward
- Which one of the following is a possibility for most of us in regard to breathing, by making a conscious effort? Justify your option. a) One can consciously breathe in and breathe out by moving the diaphragm alone, without moving the ribs at all b)The lungs can be made fully empty by forcefully breathing out all air from them c)One can breathe out air totally without oxygen d) One can breathe out air through eustachian tubes by closing both the nose and the moutharrow_forwardWhat is the largest piece of cartilage in the larynx? 2 Multiple Choice Arytenoid Thyroid Corniculate Cricoidarrow_forwardThe laryngopharynx represents the most superior portion of the pharynx, bounded superiorly by the skull base and inferiorly by the soft palate.
