Synaptic transmission

Each neuron is separated from the next by an extremely tiny gap called the ________

The electrical impulse first activates the ....

• presynaptic neuron

• synaptic cleft

• post synaptic neuron

• receptor sites

This electrical impulse triggers the release of ____________ from tiny sacs called synaptic vesicles.

• presynaptic neuron

• neurotransmitters

• post synaptic neuron

• receptor sites

The neurotransmitter is released from the presynaptic vesicle into the ________________

• presynaptic neuron

• Synaptic cleft

• post synaptic neuron

• receptor sites

The neurotransmitters fit into the ________________ in the post-synaptic neuron and either excite or inhibit the neighboring neurons

• presynaptic neuron

• Synaptic cleft

• post synaptic neuron

• receptor sites

When a neurotransmitter, such as adrenaline, increases the positive charge of the postsynaptic neuron. This increases the likelihood that the post synaptic neuron will pass on the electrical impulse. This is called...

• Excitation

• Inhibition

When a neurotransmitter such as serotonin increases the negative charge of the postsynaptic neuron. This decreases the likelihood that the post synaptic neuron will pass on the electrical impulse. This is called...

• Excitation

• Inhibition

Neurotransmitters can only travel in one way

• True

• False

Serotonin is __________

• Inhibitory

• Excitatory

If the neurotransmitter is _________ then the post synaptic neuron is more likely to fire an impulse.

• Inhibitory

• Excitatory
