What direction does the electrical signal travel through the neuron?

• From dendrites, down the Axon, and out Axon terminalsThis is a correct answer

• From Axon terminals, down the Axon, & out of the dendrites

• Any direction up or down the cell

• From the Axon, to the Dendrites, and out the Axon terminals

What do neurotransmitters do?

• Controls the actions of the neuron

• Produces food for the neuron

• Carries information from one neuron to another

• Controls speed of electrical signal through the axon

What do Dendrites do?

• Intakes information from other neurons

• Produces fatty tissue for the Myelin Sheath

• Sends information to the next cell

• Controls the speed of electrical signal through the axon
