Which part of the neuron receives signals?

• dendrite

• axon

• cell body

• myelin sheath

How do neurons trasmit a signal:

a) down a neuron / b) from neuron to neuron?

• a) electrical / b) chemical

• a) chemical / b) electrical

• a) chemical / b) chemical

• a) electrical / b) electrical

Which type of neuron would be connected to photoreceptors in your eye?

• sensory neuron

• motor neuron

• relay neuron

• connector neuron

How is the Na+/K+ pump important to neuron function?

• It sets up a negative charge in the cell = resting potential

• It sets up a positive charge in the cell = action potential

• It causes the signal to pass down the neuron = action potential

• It prevents the neuron from receiving a signal = repolarization
