Question

The apneusticcentre increases the depth of___(i)____ by acting directly on the ___(ii)____ centre. The pneumotaxiccentre inhibits the ___(iii)____ centre, thus increasing the respiratory rate i.e the duration of inspiration and expiration___(iv)____.

• A. i).➡Expiration ii).➡Expiratory, iii).➡Inspiratory iv).➡Increases.
• B. i).➡Inspiration ii).➡Inspiratory, iii).➡Expiration iv).➡Decreases.
• C. i).➡Inspiration ii).➡Inspiratory, iii).➡Expiratory iv).➡Decreases.
• D. i).➡Expiratory ii).➡Inspiratory , iii).➡Expiration iv).➡Increases.

Answer 1

The correct option is C

i).➡Inspiration ii).➡Inspiratory, iii).➡Expiratory iv).➡Decreases.

The apneusticcentre increases the depth of inspiration by acting directly on the Inspiratory centre. The pneumotaxiccentre inhibits the expiratory centre thus increasing the respiratory rate and that is the duration of inspiration and expiration decreases.
