Larynx is a part of the respiratory system and is supposed to be a complex apparatus responsible for the phonation-creation of voice. However, the extensive anatomical knowledge about the larynx does not correspond to an obscure speculation about creation of voice. Therefore the function of the larynx can be compared with the function of electro-acoustic transducers and on this basis certain roles can be ascribed hypothetically to the functional details of phonation system. The thyroidal cartilage seems to be ideal for such a comparison. Diffusion of acoustic signal by densing and diluting of an elastic milieu is due to the initial stimulus mediated by a solid and elastic sound. In case of vocal system, the initial stimuli occur stimultaneously at two sounds that behave as membranes of coaxial mechanic-acoustic resonators in the function of a radiator. Vocal cords represent a membrane of more subtile system, and the thyroid cartilage is a membrane of more robust system. The mechanism of oscillation is the subject of the present communication. It was concluded that the thyroid cartilage is not only a passive shield protecting the fine glottic structures, but on the contrary an active element of this mechanic-acoustic radiator. The recorded movements of the thyroid cartilage enabled to subtract the presence of neuroreflexive activity accompanying the vocal cycle. The anatomical structures in the vicinity of the thyroid cartilage indicate possible modifications of its motion so that the laryngeal articulation can be supposed.
What else can I help you with?
What makes up the cartilagimous structures of the larynx?
The cartilaginousÊ structures of the larynx is made up of many parts. These are the hyoid bone, epiglottis, thyroid cartilage, arytenoid cartilage, cricoarytenoid joint, vocal ligament, cricothyroid joint, cricoid cartilage, and the trachea.
What is a shark's skeleton called?
A shark's skeleton is made up of cartilage.
What kind of skeleton does a lamprey have?
Yes, it made out of cartilage just like sharks.
What is the function of endostyle and urostyle?
Endostyle are found in invertebrate chordates. It functions similarly to the thyroid found on vertebrates. The urostyle on the other hand is a bone found in a frog. It is combined with two illium bones, a pubis and ischium to create a grouping of bones that function similarly to a human pelvis.
What is the texture of the material at the end of the bone?
The material at the end of bones is called articular cartilage, which has a smooth and slightly rubbery texture. Its primary function is to reduce friction and provide cushioning between bones at the joints to allow for smooth movement.
What is the name of the large cartilage of the anterior larynx?
The most prominent cartilage in the anterior larynx is the thyroid cartilage. The thyroid cartilage is a shield shaped structure made of hyaline cartilage.
Name the specific cartilages in the larynx that forms the Adam's apple?
The cartilage that forms the Adam's apple is the thyroid cartilage.
Which is superior the thyroid or cricoid cartilage?
The thyroid cartilage is superior to the cricoid.
What is the literal meaning of thyroid?
Shaped like an oblong shield; shield-shaped; as, the thyroid cartilage., Of or pertaining to the thyroid body, thyroid cartilage, or thyroid artery; thyroideal.
What is the cartilage for broader anteriorly?
The cartilage in the larynx that forms the broader anteriorly is thyroid cartilage. Also known as Adam's Apple, it the largest of the cartilages that form the laryngeal structure.
What is the function of the cricoid cartilage?
The thyroid cartilage forms the bulk of the anterior wall of the larynx, and serves to protect the vocal folds ("vocal cords") which are located directly behind it.
Does the larynx contain thyroid cartilage?
Yes, the larynx contains the thyroid cartilage, which is the largest cartilage in the larynx and forms the "Adam's apple" in the front of the neck.
What is thyroid cartilage?
The thyroid cartilage is the largest and uppermost of nine cartilages found in the larynx. It is commonly called the Adam's apple.
What is the difference between the thyroid and cricoid cartilage in the human body?
The thyroid cartilage is larger and located higher in the neck than the cricoid cartilage. The thyroid cartilage is commonly referred to as the "Adam's apple" and is more prominent in males. The cricoid cartilage is smaller and shaped like a signet ring, located just below the thyroid cartilage. Both cartilages play a role in supporting the larynx and vocal cords.
What is the ring shaped cartilage just inferior to the thyroid cartilage?
The ring-shaped cartilage just inferior to the thyroid cartilage is the cricoid cartilage. It is located at the top of the trachea and serves as a landmark for various procedures involving the airway.
What does the thyrohyoid membrane's name indicate about its location?
Of or pertaining tot he thyroid cartilage of the larynx and the hyoid arch.
In terms of size where does the thyroid cartilage rank in the architecture of the larynx?
The thyroid cartilage is the largest of the nine cartilages that make up the laryngeal skeleton, the cartilage structure in and around the trachea that contains the larynx.
