The first thing we are going to do is determine the etymological origin of the term larynx. If we do, we discover that it comes from the Greek, specifically from the word “larygas”, which can be translated as “throat”.
Larynx is a term that refers to tubular organ between the pharynx and trachea. The larynx, which appears in most vertebrates, is made up of nine cartilages (United for ligaments and little muscles) and constitutes a key piece in the phonation apparatus of mammals.
In the human beings, the larynx is located in the anterior part of the neck and borders the upper part of the trachea. Constituted as an organ of phonation, the larynx responds to the needs of the voice and phonation by containing the upper and lower vocal cords.
Specifically, we would have to establish that the larynx is made up of six types of cartilage: arytenoid, cueniform, epiglottis, cricoid, corniculate and thyroid.
The Thyroid cartilage it is the largest of those that make up the larynx. In the case of mens, this cartilage creates a noticeable prominence on the anterior face of the neck which is known as laryngeal prominence or Adam’s apple. It should be mentioned, on the other hand, that the larynx, pharynx and trachea are covered by mucous epithelium.
In the same way, then the extrinsic ligaments, such as the thyrohyoid membrane, and the intrinsic ones, which have the function of joining the ligaments together, are also forming part of the larynx structure. Among this last group, the elastic cone or what is the elastic membrane stand out, among others.
Also in the larynx the set of muscles that it possesses are fundamental. Specifically, they are divided into two large groups:
• Intrinsic, which are responsible for the movement of the vocal cords.
• Extrinsic, which have a lot to do with what would be the fixation of the larynx as well as its movement. Examples are the thyrohyoid or the median constrictor.
How is the voice generated? With the passing of air, the vocal cords vibrate in the larynx and produce various sounds, which vary according to the tension to which they are subjected by the action of the muscles. If the tension is low, the sound produced will be serious; On the other hand, if the tension is strong, the sound will be high-pitched.
Sounds coming out of the larynx can be transformed into words thanks to the intervention of the muscles of the mouth and tongue. As the larynx and vocal cords of men are larger compared to the woman, the tone of voice between both sexes is different.
The invasion of a virus or of a bacterium, the swelling of the vocal folds and the Cancer are some of the diseases that may affect the larynx.
Of the aforementioned cancer of the larynx, we should highlight that it is identified by the following symptoms: change in voice, cough that does not disappear, ear pain, the appearance of a lump in the throat or difficulty swallowing, among others.
In these circumstances, what you have to do is go to a medical professional to resort to one or more diagnostic processes. Specifically, to perform tests such as a CT scan, a neck examination, an endoscopy …
