Question: 1 / 400

What role does the vagal nerve play in the cough reflex?

It regulates the force of the cough

It transmits sensory signals from the airways to the brain

The vagal nerve is crucial in the cough reflex as it transmits sensory signals from the airways to the brain. When irritants such as smoke or particles are detected in the respiratory tract, the sensory nerve endings in the airways are activated. These signals are carried via the vagus nerve to the brain’s cough center, which processes the information and triggers the appropriate motor response to cough. This connection is essential for initiating the cough reflex, as it ensures that protective responses to airway irritants are quickly enacted.

The understanding of this process highlights the importance of the vagal nerve not just in cough reflex but also in overall respiratory function, emphasizing its role in signaling and reflex control within the body.
