Question

Quizplus · Accepted Answer

The cardiac accelerator center is responsible for increasing heart rate and contractility. It is located in the medulla oblongata of the brainstem and is activated by the sympathetic nervous system. Therefore, the nerves used by the cardiac accelerator center are sympathetic. The vagus nerve and parasympathetic nervous system, on the other hand, are responsible for decreasing heart rate and contractility, making them unlikely candidates for the nerves used by the cardiac accelerator center.
