Webb23 aug. 2024 · Within the spinal cord, both dynorphins and enkephalins can act to reduce the transmission of pain signals in the dorsal horn. This is because the post-synaptic ends of second-order neurones have opioid receptors within the membrane. In addition, the pre-synaptic ends of first-order neurones contain opioid receptors. WebbNeurotransmission (Latin: transmissio "passage, crossing" from transmittere "send, let through") is the process by which signaling molecules called neurotransmitters are released by the axon terminal of a neuron (the presynaptic neuron), and bind to and react with the receptors on the dendrites of another neuron (the postsynaptic neuron) a ... mae west fred west\u0027s daughter
