neuron

This insulating material forms a layer, around the axon of a neuron.  It enables electrical signals to travel down the axon at higher speeds.

• neuron
• myelin sheath
• dendrite
• neurotransmitter

NGSS.MS-LS1-8

The tiny gap between neurons where nerve impulses are sent from one neuron to another.  It is where communication occurs between an axon and dendrite

• synapse
• axon terminal
• impulse
• myelin

The correct direction of the neural impulse within one neuron.

• Axon Terminal to Dendrite
• Dendrite to Axon Terminal
• Cell Body to Axon
• Axon Terminal to Cell Body

This is the electrical charge that travels down an axon when a neuron is firing

• Resting Potential
• Action Potential
• Threshold
• Refractory Period
