Neurons, Action Potentials, & Synapses

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

• positive
• negative

Describes the fact that a neuron fires at the same intensity despite the intensity of the stimulus.

• Threshold
• Repolarization
• All or None Principle
• Action Potential

When a neuron is not engaged in an impulse.

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

The sodium-potassium pump creates 

• magnetic energy
• electrical energy
• light energy
• sound energy

Neurotransmitters are released from the

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

Acetylcholine (ACh) is heavily involved with 

• muscle movements
• making memories
• blocking pain
• elevating mood

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

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

Heroin mimics the effects of this neurotransmitter.

• Dopamine
• Serotonin 
• Endorphin
• Norepinephrine 

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

• Resting potential
• Reuptake
• Retroactivity
• Repolarization

The reward center of the brain is most closely associated with this neurotransmitter's pathways.

• Dopamine
• Serotonin
• GABA
• Ach
