Laryngeal paralysis in animals is a condition in which the nerves and muscles that control the movements of one or both arytenoid cartilages of the larynx cease to function, and instead of opening during aspiration and closing during swallowing, the arytenoids remain stationary in a somewhat neutral position. Specifically, the muscle that ...
Investigations into idiopathic laryngeal paralysis by two groups (in Michigan and Tennessee) between 2005 and 2013 showed that dogs with ILP did not only suffer dysfunction of the laryngeal nerves; they found that this was just one prominent symptom of what was a very gradually progressing polyneuropathy of old age, which also affected other ...
Laryngeal paralysis is unilateral or bilateral paralysis of the larynx. In dogs it can be congenital, seen in the Bouvier des Flandres, Bull Terrier, Dalmatian, Rottweiler and Huskies, or an acquired, idiopathic disease, seen in older Labrador Retrievers, Golden Retrievers, St. Bernards, and Irish Setters.

Tick paralysis is an acute, ascending motor paralysis that occurs in dogs and cats. [15] The cause is a neurotoxin in the saliva of certain species of adult ticks . Dermacentor species predominate as a cause in North America, while Ixodes species mainly cause the disease in Australia. [ 1 ]
Vocal cord paresis, also known as recurrent laryngeal nerve paralysis or vocal fold paralysis, is an injury to one or both recurrent laryngeal nerves (RLNs), which control all intrinsic muscles of the larynx except for the cricothyroid muscle. The RLN is important for speaking, breathing and swallowing.
The vagus nerves, from which the recurrent laryngeal nerves branch, exit the skull at the jugular foramen and travel within the carotid sheath alongside the carotid arteries through the neck. The recurrent laryngeal nerves branch off the vagus, the left at the aortic arch, and the right at the right subclavian artery. The left RLN passes in ...
A new problem has been found during the production of 737 Max jets that will force Boeing to rework about 50 planes that have not yet been delivered.
The laryngeal cavity (cavity of the larynx) extends from the laryngeal inlet downwards to the lower border of the cricoid cartilage where it is continuous with that of the trachea. [ 11 ] [ 12 ] It is divided into two parts by the projection of the vocal folds , between which is a narrow triangular opening, the rima glottidis .
