Synapses and Neurotransmitters

The structure within the presynaptic neuron's axon terminal that contains neurotransmitter waiting to be released:

• chemical synapse

• synaptic vesicle

• postsynaptic neuron

• synaptic neuron

The name for the very narrow gap between the two cells in a synapse:

• synaptic cleft

• electrical synapse

• chemical synapse

• ganglion

A chemical released by neurons into a synapse to send a signal to another cell:

• synaptic vesicle

• electrical synapse

• neurotransmitter

• action potential

The structure at the end of a neuron's axon at a chemical synapse that contains and releases neurotransmitter:

• axon terminal

• electrical synapse

• postsynaptic neuron

• presynaptic neuron

The term for the reabsorption from a synaptic cleft of neurotransmitters by the pre-synaptic neuron that released it:

• enzymatic hydrolysis

• break down

• reuptake

• hyperpolarization
