The first thing we are going to do is determine the etymological origin of the term larynx. If we do this, we discover that it comes from the Greek, specifically the word "larygas", which can be translated as "throat."
Larynx It is a term that refers to tubular organ that sits between the pharynx and trachea . The larynx, which appears in most vertebrates, is formed by nine cartilage (United for ligaments and little muscles ) and constitutes a key piece in the phonation apparatus of mammals
In the Humans , the larynx is located in the anterior part of the neck and borders the upper part of the trachea. Established 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.
He Thyroid cartilage It is the largest of those that make up the larynx. In the case of mens , said cartilage creates a noticeable prominence in the anterior aspect of the neck which is known as laryngeal prominence or adam nut . It should be mentioned, on the other hand, that the larynx, pharynx and trachea are covered by mucous epithelium .
In the same way, then they are also part of the structure of the larynx what are the extrinsic ligaments, such as the thyrohyoid membrane, and the intrinsic ones, whose function is to join the ligaments together. Among the latter group are the elastic cone or what is the elastic membrane, among others.
Also in the larynx are the set of muscles that it has. 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 the larynx fixation would be as well as its movement. Examples are the thyrohyoid or the middle constrictor.
How is the voice generated? With the passage 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.
The sounds that come 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 one bacterium , the swelling of the vocal folds and the Cancer are some of the diseases that can affect the larynx.
Of the cited larynx cancer we should highlight that it is identified by the following symptoms: change in the voice, cough that does not go away, earache, the appearance of a lump in the throat or difficulty swallowing, among others.
In these circumstances, what must be done is to 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 ...
