Neurotransmitters

A) stimulate presynaptic terminals.
B) remain in the synaptic cleft for long periods of time.
C) bind irreversibly to the receptor molecules of the postsynaptic membrane.
D) cause the production of action potentials in the postsynaptic membrane.
E) do not affect membrane channels in the postsynaptic membrane.

Neurotransmitters

Chemicals released by nerve cells to transmit signals across a synapse to another nerve cell, muscle cell, or gland cell.

Synaptic Cleft

Space between the presynaptic and the postsynaptic membranes.

Postsynaptic Membrane

The part of the cell membrane of a neuron that is on the receiving end of a synapse, where neurotransmitter receptors are located.
