Select the best statement regarding the respiratory centers:
The coex can override the function of the respiratory centers, during voluntary hyperventilation, or voluntary breath holding. The other choices are incorrect: The normal rhythmic pattern of breathing originates in the brain stem, not the coex. Expiration is passive during quiet breathing, impulses from the pneumotaxic center inhibit inspiration, and the output from the respiratory centers includes impulses from the spinal cord to the intercostal and other muscles in addition to the phrenic nerves.
The normal rhythmic pattern of breathing originates from neurons in the motor area of the coex
During quiet breathing, expiratory neurons fire actively
Impulses from the pneumotaxic center can stimulate inspiratory activity
The coex of the brain can override the function of the respiratory centers
