Nervous System

The part of a neuron that receives information from other neurons

• axon
• dendrites
• myelin sheath
• synapse

A signal molecule that transmits nerve impulses across synapses is a

• neuron
• neurotransmitter
• nerve
• action potential

Which ions are involved in the electrical nerve impulse?

• Iodine and Sodium
• Potassium and Sodium
• Iron and Sodium
• Calcium and Iodine

-70 mV is the measure of a

• Threshold Potential
• Action Potential
• Resting Potential
• End Point Potential

A membrane potential becoming less negative is called

• hyperpolarization
• depolarization
• repolarization
• polarization
