A Map Of Dominica for the sympathetic nervous system involved in activation and arousal ? the fight?flight response; . the parasympathetic nervous system involved in relaxation ? the rest?recover response. Both sets of nerves arise in an area in the brainstem known as the medulla oblongata which is linked to the hypothalamus. From this, they pass down the spinal cord to various synapses, where they link to a second series of nerves that are linked to all the key body organs, including the heart, arteries and muscles Figure For the sympathetic arm, the neurotransmitter involved at the synapse between the spinal cord nerves and the nerve to the target organ is acetylcholine. Activity at the synapse between this second nerve and the end organ mainly involves a neurotransmitter known as noradrenaline known alternatively as norepinephrine and to a lesser extent adrenaline epinephrine. The parasympathetic system uses acetylcholine at both synapses. The activity in each of the organs depends on the relative activity in the sympathetic and parasympathetic nervous systems.
