Solution:

The neurogenic heart is a characteristic feature of most arthropods and some annelids. In this, the heart beat is initiated by a nerve impulse coming from a nerve ganglion situated near the heart. The myogqnic heart is a characteristic feature of molluscs and vertebrates. In this, heart beat is initiated by a patch of modified heart muscle itself.
