| This quantal release of neurotransmitter has a critical influence on the electrical potential created in the postsynaptic membrane. |
| Acetylcholine receptors are ion channels that span the postsynaptic membrane, and they have extracellular, intramembranous, and cytoplasmic portions. |
| Venoms of the Elapidae snakes contain several postsynaptic polypeptide neurotoxins, such as bungarotoxin isolated from the venom of the banded krait. |
| When postsynaptic receptors are saturated, a quantum of synaptic current corresponds to the response evoked in a single synaptic bouton. |
| Glutamate is released presynaptically and binds to a postsynaptic receptor gating a cation-selective channel, thus depolarizing the post-synaptic cell. |
| Most knowledge of postsynaptic neurotransmitter receptors comes from studies of the receptor on muscle cells. |
