[citation needed] Bed rest interferes with the expansion of the chest and limits the amount of air that can be taken into the lungs in preparation for coughing, making the cough weak and ineffective. [ citation needed ] This reflex may also be impaired by damage to the internal branch of the superior laryngeal nerve which relays the afferent ...
Additionally, the nerves are among the few nerves that follow a recurrent course, moving in the opposite direction to the nerve they branch from, a fact from which they gain their name. The recurrent laryngeal nerves supply sensation to the larynx below the vocal cords, give cardiac branches to the deep cardiac plexus , and branch to the ...
Successful joint models of medullary systems coordinating breathing, coughing and swallowing has been constructed based on this model. [4] [5] Coughing can occur or be inhibited as a voluntary action, suggesting control from higher systems in the brain. Functional brain imaging of voluntary, suppressed, and induced coughing show that a number ...
The hypersensitivity of vagal afferent nerves causes refractory or idiopathic cough. Arnold's nerve ear-cough reflex, though uncommon, is a manifestation of a vagal sensory neuropathy and this is the cause of a refractory chronic cough that can be treated with gabapentin. The cough is triggered by mechanical stimulation of the external auditory ...
Control your cough. Coughing is a physiologic way to rid one of some of the congestion, says Amesh A. Adalja, M.D., senior scholar at the Johns Hopkins Center for Health Security. Controlled cough ...
Irritation of the internal laryngeal nerve results in uncontrolled coughing - usually as a result of food or water in the laryngopharynx. The lesion of this branch (for example, during surgery) that seeks an anterior approach to the cervix, is associated with a loss of the laryngeal reflex of cough and an elevated risk of aspiration pneumonia.
To its sides run the carotid arteries and inferior thyroid arteries; and to its sides on its back surface run the recurrent laryngeal nerves in the upper trachea, and the vagus nerves in the lower trachea. [2] The trachealis muscle contracts during coughing, reducing the size of the lumen of the trachea. [3]
A cough is initiated by a deep inhalation through the vocal cords, followed by the elevation of the larynx and the tight adduction (closing) of the vocal cords. The forced expiration that follows, assisted by tissue recoil and the muscles of expiration, blows the vocal cords apart, and the high pressure expels the irritating object out of the ...
