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

Cardiac activity is influenced by both parasympathetic and sympathetic nervous system.

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.
