Synaptic Cleft

The small gap between the presynaptic and postsynaptic neurons across which neurotransmitters are released to transmit signals.

Postsynaptic Cell

The neuron or cell that receives a signal (neurotransmitters) from another neuron at a synapse.

Neurotransmitter

Chemicals released by neurons at synapses, which transmit signals across a chemical synapse from one neuron to another neuron, muscle cell, or gland cell.
