The sensation of chest tightness due to an impending asthmatic attack appears to be related to which of the following physiological causes?

Question

A) Transmission of excessive chemoreceptor stimulation of the medullary respiratory center.
B) Uncomfortable work of breathing sensation is thought to be mediated by excessive input from stretch receptors in the chest muscles.
C) A perceived shortness of breath is a multidimensional sensation involving both the sensory intensity and unpleasantness.
D) Input from lung receptors that monitor bronchial constriction.

Answer 1

Ans: D
Feedback:
The sensation of chest tightness due to an impending asthmatic attack appears to be related to input from lung receptors that monitor bronchial constriction. Transmission of excessive chemoreceptor stimulation of the medullary respiratory center to sensory centers in the forebrain relates to air hunger. Labored breathing, an uncomfortable work of breathing sensation, is thought to be mediated by excessive input from stretch receptors in the chest muscles. A perceived shortness of breath, known as dyspnea, is a multidimensional sensation involving both the sensory intensity and unpleasantness.
