PAIN, DRAWING


Representation of the inhibition at the level of the spinal cord. The presynaptic neuron releases the neurotransmitters of the pain via synaptic vesicles. These neurotransmitters are released in the synaptic cleft and fixes on the receptors of the synapse of the postsynaptic neuron. The nerve impulse is then created and the information of the pain is transported to the brain. To fight against the pain the neuron of the inhibition will secrete endorphin (neurotransmitters represented by the blue balls). The endorphin fixes on the membrane receptors of the postsynaptic neuron instead of the neurotransmitters of the pain. The information of the pain is not transmitted.
