12 ATAR Human Bio - Action Potential

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 Response

• Action Potential

When a neuron is not engaged in an impulse.

• Resting membrane potential

• Action potential

• Neural potential

• Synaptic potential

Neurotransmitters are released from the

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

The area of the neuron that receives an impulse

• dendrite
• axon
• node of ranvier
• nucleus

The area of the neuron that transmits an impulse

• dendrite
• axon
• cell body
• nucleus

This neuron sends the impulse and releases neurotransmitters

• presynaptic cell
• postsynaptic cell

This neuron receives the impulse and has receptor sites for neurotransmitters

• presynaptic cell
• postsynaptic cell

During depolarization Sodium (Na+) moves __________

• into the cell
• out of the cell

During repolorization Potassium (K+) moves __________

• into the cell

• out of the cell
