Autonomic Innervation of the Heart

3D illustration showing the autonomic pathways between the central nervous system and the heart. The image shows a cross section of the brain and brain stem with simplified graphic versions of the vagus nerve and cardiac nerves traveling to an image of the heart. The vagus nerve originates from the medulla oblongata. Text labels indicate that it is part of the parasympathetic system and works to decrease the heart rate. The cardiac nerves originate from the spinal cord. Text labels indicate that they are part of the sympathetic system and work to increase heart rate and force contraction.
