Neuron Structure

The long, fiber like part of a neuron which the cell sends information to receiving neurons

• axon 

• dendrite

• axon terminal

• gene

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

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

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
