Sympathetic and Parasympathetic Nerves Supplying the Heart Labelled in Finnish

Image Description:

Sympathetic and parasympathetic nerves supplying the heart. The sympathetic nervous system acts on the Sinoatrial Node, speeding up the depolarisation rate, and therefore increasing the heart rate. The parasympathetic system works in reverse in order to slow the heart rate down.
