Question

Pneumotaxic centre is present in

• A. cerebrum
• B. cerebellum
• C. medulla oblongata
• D. pons varolii

Hint:

The pneumotaxic center is a vital component of the respiratory control system in the brain. 

Answer 1

The Correct Option is D

The correct answer is Option D) pons varolii

Pneumotaxic centre is located in the dorsal part of pons varolii. It sends signals to all the neurons of dorsal respiratory group and only to inspiratory neurons of dorsal respiratory group. Its main job is to primarily limit inspiration.

Answer 2

The correct answer is Option D) pons varolii

Real Life Applications

1)The pneumotaxic center is in the treatment of sleep apnea. 
2)pneumotaxic center is in the treatment of respiratory failure. 
3)Also used to control of other respiratory reflexes, such as the cough reflex and the sneeze reflex.

Answer 3

The correct answer is Option D) pons varolii

The pneumotaxic center is a vital component of the respiratory control system in the brain. Located within the pons region, it plays a crucial role in regulating the rate and depth of breathing. 

• The pneumotaxic center is a group of neurons located in the upper part of the pons region of the brainstem.
• It is part of the respiratory centers, along with the medullary respiratory centers.

Role in Respiratory Control

• The primary function of the pneumotaxic center is to regulate the duration and frequency of each breath.
• It works in conjunction with other respiratory centers to maintain a balance between inhalation and exhalation.

Control of Breathing Pattern

• The pneumotaxic center sends inhibitory signals to the inspiratory centers in the medulla.
• By regulating the inspiratory centers, the pneumotaxic center plays a crucial role in controlling the timing and termination of inspiration.
• It limits the duration of each breath and prevents excessive lung inflation by promoting shorter inhalation periods.

Interaction with the Dorsal Respiratory Group (DRG)

• The pneumotaxic center interacts with the dorsal respiratory group (DRG), a part of the medullary respiratory centers.
• The DRG initiates the process of inhalation, while the pneumotaxic center helps to regulate its duration.
• This interplay ensures the coordination of inhalation and exhalation during the breathing cycle.

The pneumotaxic center, located in the pons region of the brain, plays a critical role in regulating the rate and depth of breathing. By modulating the duration and frequency of each breath, it ensures the coordination of the respiratory cycle.
