What are the laryngeal cartilages?
The laryngeal skeleton is nine cartilages: the thyroid cartilage, cricoid cartilage, epiglottis, arytenoid cartilages, corniculate cartilages, and cuneiform cartilages. The first three are unpaired cartilages, and the latter three are paired cartilages.
Do cats have laryngeal ventricles?

What is cat Laryngospasm?
Laryngospasm is a common complication encountered when intubating cats. Physical, chemical and thermal stimulation of the larynx and upper airway can produce this reflex, though the trigger in this case was unknown.
What are the 3 main functions of the larynx?
Introduction. The larynx serves three important functions in humans. In order of functional priority, they are protective, respiratory, and phonatory.
Which is the largest laryngeal cartilage?

What does the larynx do in a cat?
Disease of the Voice Box or Larynx in Cats. The voice box, or larynx, serves as a passage for airflow from the external environment to the lungs. It protects the lungs from aspiration during swallowing and regurgitation, and allows for vocalization (such as meowing).
Where are the laryngeal muscles located in a cat?
There are two pairs of tissue folds at the cranial end of the feline larynx; the false vocal cords that lie more cranially and laterally, while the true vocal cords lie more caudally and nearer the median plane. The laryngeal ventricles are reported to lie between the true and false vocal cords on each side.
What does laryngospasm feel like?
When laryngospasm occurs, people describe the sensation of choking and are unable to breathe or speak. Sometimes, the episodes occur in the middle of the night. A person may suddenly awaken feeling as though they are suffocating. This condition is called sleep-related laryngospasm.
How can I prevent my cat from laryngospasm?
Make sure the cat is adequately anesthetized before attempting intubation. Attempting to intubate a cat in a light anesthetic plane is likely to cause coughing and laryngospasm. Simply increasing the depth of anesthesia will allow intubation in most cases. Use topical viscous lidocaine to desensitize the larynx.
What is main function of larynx?
The larynx serves to protect the lower airways, facilitates respiration, and plays a key role in phonation. In humans the protective and respiratory functions are compromised in favor of its phonatory function.
