Neurons and Neurotransmitters
... Neurotransmitters: Chemical messengers that cross the synaptic gaps between neurons. When released by the sending neuron, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron’s dendrites, thereby influencing whether that neuron will generate a neural impulse ...
