The inspiratory and expiratory medullary neurons are connected to projections from higher brain centres and from chemoreceptors and mechanoreceptors; in turn they drive cranial Neurally, inspiration is characterized by an augmenting discharge of medullary neurons that terminates abruptly. Apneustic breathing results when this area is damaged.Vagus nerve (CN10) stretching of lungs during inspiration initiates vagal afferent to inhibit inspiratory discharge.

Our editors will review what you’ve submitted and determine whether to revise the article.This flexibility in breathing patterns in large part arises from sensors distributed throughout the body that send signals to the respiratory neuronal networks in the brain.

Test. respiratory control centers: The medulla which sends signals to the muscles involved in breathing, and the pons which controls the rate of breathing. Conversely, the Botzinger complex is believed to have expiratory active/inspiratory inhibitory neurons.

In essence, chemical control determines minute ventilation, whereas neural control determines the most efficient pattern to achieve that ventilation with the minimum expenditure of work. This formula is more important as an illustration that no single factor controls ventilation than as a quantitative estimate.The way in which hypoxia and hypercapnia combine to stimulate breathing is shown in Asphyxia is a combination of hypoxia and hypercapnia and the ventilatory response to it is greater than the response to the sum of its parts.Response to chronic hypercapnia reduces with time because the environment of the central chemoreceptors is actively restored to normal.An analogous disorder occurs in patients with bilateral hemispherical disorders (especially elderly patients with diffuse cerebrovascular disease).
