This is the commonest symptom of nearly all respiratory diseases and is indicative of an effort to expel a foreign substance causing irritation on any place in the cough reflex path.
The center is in the medulla close to the respiratory centers. This is activated reflexly by the afferent impulses traveling up mostly along the vagus and to a less extent, the vagus and the phrenic (to bronchi and diaphragm), the spinal accessory, intercostals and other nerves supplying the accessory muscles of respiration. The peripheral fibres of the vagus and the phrenic are also sometimes directly affected causing cough reflex.
The medullary center itself may also be excited or restrained by impulses from superior cerebella centers, so that cough may be induced or controlled by voluntary efforts.
Cough is usually due to disturbances in the respiratory passage or pleurae, irritation in the nose and the ear or sometimes in the abdominal viscera inflammation or irritation.
It is important to make a note of the age of the patient, duration of the cough also what part of the day or night it is worst, voice is affected or not and if paroxysmal, painful or associated with any change of posture or vomiting.
In the morning is often due to bronchitis, bronchiectasis or tubeculous cavity. Night's accumulated secretion is coughed out. If expectoration is absent non-productive cough, either there is simple congestion of the mucous membranes especially of the upper respiratory tract or such extra- pulmonary conditions as pleurisy or it is a reflex from other viscera.
