Illustration of pain receptors. A presynaptic neuron releases pain neurotransmitters (red spheres), which connect to the receptors of the synapse. To counteract this, a neuron will secrete endorphins (blue spheres), which bind to receptors, blocking pain neurotransmitters from binding with the receptors.
