Reflex responsible for tachycardia during right ventricle distention is: 
Select and explain. 
A. Bezold-jaisch reflex, B. Brainbridge reflex, C. Cushing reflex, D. J -reflex
B: Brainbridge reflex
Answer: B: Brainbridge reflex 
Explanation: Bezold-jaisch reflex: produces hypoapnoea and bradycardia Brainbridge refex: responsible for tachycardia due to ventricular distention Cushing reflex:it is physiological nervous response to increased intracranial pressure which produces Cushing triad of increased blood pressure, irregular breathing, bradycardia. J -reflex: inhibition of stomatic smooth muscle due to stimulation of j receptors in the alveoli. Ref: Guyton and Hall textbook of medical physiology 12th edition, page number: 373
