[citation needed] This reflex may also be impaired by damage to the internal branch of the superior laryngeal nerve which relays the afferent branch of the reflex arc. [ citation needed ] This nerve is most commonly damaged by swallowing a foreign object, such as a chicken bone, resulting in it being lodged in the piriform recess (in the ...
Dextromethorphan hydrobromide affects the signals in the brain that trigger the cough reflex. It is used as a cough suppressant, although it can sometimes be used, medicinally, as a pain reliever, and is also used as a recreational drug.
The cough center is a region of the brain which controls coughing. The cough center is located in the medulla oblongata in the brainstem . Cough suppressants focus their action on the cough center.
Central neurogenic hyperventilation (CNH) is an abnormal pattern of breathing characterized by deep and rapid breaths at a rate of at least 25 breaths per minute. Increasing irregularity of this respiratory rate generally is a sign that the patient will enter into coma .
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 central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
The underlying mechanism involves the nervous system slowing the heart rate and dilating blood vessels, resulting in low blood pressure and thus not enough blood flow to the brain. [2] Diagnosis is based on the symptoms after ruling out other possible causes. [3] Recovery from a reflex syncope episode happens without specific treatment. [2]
[7] [8] This dampens their activity and reduces the cough reflex. [7] [3] Benzonatate also has central antitussive activity on the cough center in central nervous system at the level of the medulla. [7] [5] However, there is minimal inhibition of the respiratory center at a therapeutic dosage. [3]
