Question 1 of 5
While walking down the street, a cat jumps out of an alley into the pathway of an adult. They note that his /her heart is 'racing.' this response is primarily due to:
Correct Answer: D
Rationale: The correct answer is D because when the cat jumps out causing a fight or flight response, the sympathetic nervous system is activated. This leads to the secretion of adrenaline and noradrenaline from the adrenal medulla, which in turn increases heart rate. Option A is incorrect as it refers to motor neurons in the brain stem, not related to the heart rate response. Option B is incorrect as the ANS is not directly responsible for the heart rate increase in this scenario. Option C is incorrect as the parasympathetic nervous system would actually decrease heart rate, not increase it.
