Synapses

What chemical is activated by the action potential in the presynaptic neuron that causes the vesicles containing neurotranmitters to move toward the synaptic cleft?

• calcium

• potassium

• sodium

• phosphorus

Neurotransmitters are released from the

• Dendrites

• Post-synaptic neuron

• Presynaptic neuron

• Schwann Cells

Excess neurotransmitters in the synapse that goes back into the presynaptic neuron.

• Resting potential

• Reuptake

• Retroactivity

• Repolarization

Y

• Axon Terminal Button

• Neurotransmitters

• Dendrite

• Synapse

Z

• Axon Terminal Button

• Neurotransmitters

• Dendrite

• Synapse

W

• Axon Terminal Button

• Neurotransmitters

• Dendrite

• Synapse

The cell in a chemical synapse that is receiving the neurotransmitter:

• chemical synapse

• postsynaptic neuron

• axon terminal

• presynaptic neuron

These send electrical impulses to neighbouring neurons.

• Synapses

• Axon

• Dendrites

• Nucleus

Receive electrical impulses from the neighbouring neurons.

• Dendrites

• Axon

• Soma

• Nucleus

What is the primary function of a synapse in the nervous system?

• Transmit electrical signals

• Transmit chemical signals

• Store neurotransmitters

• Generate action potentials
