What is the concept of larynx

The larynx is what we are familiar with. Speaking and singing are inseparable from it, which means that it is the key to vocalization. It plays a vital role in our human body, but many people only know that it is a part of our body and must be indispensable, but they don’t understand what its true meaning is and how many roles it plays. There are so many questions that leave us confused and puzzled. So what is the concept of larynx?

Vertebrates at an evolutionary level above amphibians (frogs, toads, salamanders, etc.) have a trachea whose specialized beginning part connecting to the pharynx is called the larynx. Used to protect the trachea or as a vocal structure. It is also the place where the trachea and esophagus separate. The laryngeal cartilages evolved from the branchial arches support the laryngeal wall, while the laryngeal wall of animals below birds is underdeveloped and only has cricoid cartilages and arytenoid cartilages.

The importance of laryngeal position in singing has been recognized by most vocal teachers and singers. Whether the larynx is placed correctly when singing directly affects the quality of the singing voice.

Explanation: Among vertebrates, animals above the amphibians have a trachea, and the specialized starting part that connects to the pharynx is called the larynx.

The laryngeal cartilages evolved from the branchial arches support the laryngeal wall, while the laryngeal wall of animals below birds is underdeveloped and only has cricoid cartilages and arytenoid cartilages. In mammals, the structure becomes more complex with the addition of thyroid cartilage and epiglottis cartilage.

The opening of the larynx toward the pharynx constitutes the laryngeal opening, or the glottis formed by the longitudinal fissure, which can open and close appropriately (this fissure is called the glottic fissure, and some structures that constitute the glottis fissure are different from the glottis). The left and right mucosal folds that hold the glottis can open between the cartilages and are called vocal cords. They have become the vocal device in amphibians and mammals.

In addition, above the glottis of mammals, there is a flap-like protrusion called the epiglottis where it connects to the root of the tongue. The laryngeal cavity above the vocal cords is called the laryngeal vestibule, which opens to the pharynx, that is, the upper opening of the laryngeal cavity is different from the glottis and is called the laryngeal opening. When swallowing food, the epiglottis covers the throat opening. Its predecessor is believed to be a mucosal fold, which can be seen in some reptiles. The primitive pharynx forms a tubular bulge on its ventral wall behind it to form the larynx, which branches and extends repeatedly backward to form tissue differentiation from the trachea to the alveoli.

After reading the above introduction to the concept of larynx, I think everyone should have some understanding of it. The larynx is not only important to our human body, but it also plays a vital role in the bodies of various animals, so we must protect it well and try to avoid eating too much spicy and irritating food to damage it.
