Synapses and Action Potentials

X

• Axon Terminal Button
• Neurotransmitters
• Dendrite
• Synapse

Neurotransmitters are released from the

• Dendrites
• Post-synaptic neuron
• Presynaptic neuron
• Axon

When a neuron is resting, the inside of the axon has a ____________ charge.

• positive
• negative

What generates a nerve impulse on the post-synaptic membrane? 

• Calcium binding with a receptor site
• Potassium leaking into the post-synaptic membrane 
• Neurotransmitter binding with receptor sites
• Neurotransmitter being removed from the synapse

What is the chemical used by a neuron to transmit an impulse across a synapse to another nerve cell?

• Neurotransmitters
• Synapse
• Threshold
• Impulse

When a neuron is not engaged in an impulse.

• Resting potential
• Action potential
• Neural potential
• Synaptic potential

In order for a neuron to have an action potential, the neuron must receive more

• excitatory neurotransmitters
• inhibitory neurotransmitters
• agnostic neurotransmitters
• antagonistic neurotransmitters

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

• Resting potential
• Reuptake
• Retroactivity
• Repolarization
