Expert Solution
Summary Introduction


On the basis of the information received from different areas, the respiratory centers activate the ventilator pattern. The major areas are the peripheral chemoreceptors and central chemoreceptors. Apart from these two, other factors such as, Hering-Breuer reflex, irritant reflex, deflation reflex, peripheral proprioceptor, juxtapulmonary-capillary receptors, hypothalamic control, and aortic and carotid sinus baroreceptor reflexes also influence the rate and depth of breathing.

Explanation of Solution

Justification for the correct answer:

Option (D) is, ‘1 and 3 only.’ This option is correct, as sudden pain inhibits the proprioceptors which send signals to the medulla, which in turn decreases the inspiratory signals. Therefore, a sudden pain causes a short period of breathing cessation. The sympathetic centers are stimulated by strong emotions. A decrease in body temperature also causes the respiration rate to decrease, and sudden cold might cause apnea for a short duration. Hence, option (D) is the correct answer.

Justification for the incorrect answers:

Option (A) is, ‘1 only...
