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 ...
[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 ...
This nerve may be involved by the glomus jugulare tumour. Laryngeal cancer can present with pain behind the ear and in the ear - this is a referred pain through the vagus nerve to the nerve of Arnold. In a small portion of individuals, the auricular nerve is the afferent limb of the Ear-Cough or Arnold Reflex. [3]
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 ...
The Pancoast tumor was first described by Hare in 1838 as a "tumor involving certain nerves". [2] It was not until 1924 that the tumor was described in further detail, when Henry Pancoast, a radiologist from Philadelphia, published an article in which he reported and studied many cases of apical chest tumors that all shared the same radiographic findings and associated clinical symptoms, such ...
The solitary nucleus is the end-point for sensory information arriving from the pontine respiratory group, and from two cranial nerves – the vagus nerve, and the glossopharyngeal nerve. The solitary nucleus sends signals to the respiratory center from peripheral chemoreceptors , baroreceptors , and other types of receptors in the lungs in ...
A dad, 45, had what seemed like a pinched nerve. It was a sign of a cancerous thymoma. Chest pain, shortness of breath were signs of his thymoma.
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.
