WebStephenson, F. A., & Hawkins, L. M. (2001). Neurotransmitter Receptors in the Postsynaptic Neuron. Encyclopedia of Life Sciences. doi:10.1038/npg.els.0000284 Neurotransmitter (NT) receptors are located on the surface of neuronal and glial cells. At a synapse, one neuron sends messages to the other neuron via neurotransmitters. Therefore, the postsynaptic neuron, the one receiving the message, clusters NT receptors at this specific place in its membrane. NT receptors can be inserted into any region of the neuron's membrane such as dendrites, axons, and the cell body. Receptors can be located in different parts of the body to ac… WebReceptors for that neurotransmitter determines whether it'll have an excitatory or inhibitory effect. If the receptor for that neurotransmitter is ionotropic, the activation of that receptor will open or close certain ion channels, thereby altering the membrane potential of the … Neurotransmitter binds to receptors on target cell (in this case, causing positive … So the distance between the presynaptic neuron and the postsynaptic neuron is … grays surgical anatomy pdf
