In modifying cardiac activity, the parasympathetic innervation comes from the cardio acceleratory center in the brain and the sympathetic innervation comes from the cardioinhibitory center in the brain.1. True2. False

Explanation:

The autonomic nervous system consists of three branches-sympathetic, parasympathetic and enteric nervous system. Sympathetic nervous system increases the heart rate whereas parasympathetic nervous system decreases the heart rate. So, the parasympathetic innervation comes from cardio-inhibitory center of the brain and sympathetic innervation comes from cardio-acceleratory center of the brain.

So, the answer is false.
