Vocal Cord
The vocal cords perform a very sensitive function for humans, which is the emission of sound. Therefore, any crisis in the vocal cords leads to the loss of the ability to produce sound, hence its great importance. Consequently, the role of vocal cord procedures is also magnified as they are the cause of restoring sound to humans.
Historically, when any problem occurred in the vocal cords, the fate of the individual was the loss of the ability to produce sounds. Consequently, they couldn't speak and lost one of the most important senses distinguishing humans, which is the ability to speak. Even shouting lacked the power to be done. However, with medical advancements and the emergence of vocal cord procedures, there is hope that humans can regain the ability to speak again, thus highlighting the importance of these procedures.
Given the importance of the vocal cords to humans, we disclose through the following lines all the important information about them and the diseases that affect them, such as vocal cord inflammation, vocal cord rupture, and vocal cord injection procedures, in order to avoid injury or any crisis that may cause a loss of the ability to speak.
Vocal Cord Definition
In order to understand the problems that lead to a loss of the ability to speak or the emission of sound, it is necessary to know the definition of the vocal cords or vocal cords, which are a group of muscular fibers located inside the throat.
The vocal cord is a thin muscle located inside the throat, but it does not exist alone, as there is another muscle as well, and both together are called "vocal cords."
The vocal cords are always in a relaxed position, resembling the shape of the letter V, in order to allow air to pass freely. The vocal cord is responsible for producing and emitting sound and breathing through its contraction and relaxation, with the vagus nerve controlling the vocal cord.
When you see the vocal cord, you notice its white color due to the low blood circulation through it. As for how the sound is emitted, it occurs through the release of air from the trachea through the vocal cord, leading to its vibration, resulting in sound. However, in this case, it is closed because the vocal cords are in constant motion, being closed during speech and open during breathing.
Vocal Cord Function
- Speaking: A tube that allows speaking and the ability to produce sounds by closing the vocal cords and allowing air to pass through them, with their vibration resulting in sound or speech.
- Swallowing: Occurs when the vocal cord is closed during food intake to prevent food and liquids from entering the trachea.
- Respiration: Occurs when the vocal cords remain open during breathing to allow air to pass through them.
