Current Question (ID: 14385)

Question:

What is the primary function of the Pneumotaxic Center in the regulation of respiration in human beings?

Options:

1. It increases the rate and depth of breathing
2. It decreases the rate of and depth of breathing
3. It controls the "switch off" point of inspiration
4. It initiates the "Herring-Breur" reflex

Solution:

The primary function of the Pneumotaxic Center in the regulation of respiration in human beings is to control the "switch off" point of inspiration. The Pneumotaxic Center is located in the pons region of the brainstem and is responsible for controlling the duration and frequency of breathing. It does this by regulating the depth and rate of inspiration, helping to prevent overinflation of the lungs. When the Pneumotaxic Center is activated, it signals the inspiratory neurons to switch off, causing expiration to occur. This helps to ensure that the respiratory cycle remains balanced and that the body receives the appropriate amount of oxygen and expels carbon dioxide.
