• Dendrites

• Axon Terminals

• Myelin Sheath

• Schwann Cells

What direction foes 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 does the neuron's Myelin Sheath do?

• Controls the actions of the neuron

• Produces food for the neuron

• Carries information from the cell body to other neuronsThis is a wrong answer

• Surrounds and insulates 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

Which is the correct sequence in the transmission of a neural impulse?

• axon, dendrite, cell body, synapse
• dendrite, axon, cell body, synapse
• synapse, axon, dendrite, cell body
• dendrite, cell body, axon, synapse

The brain's supporting cells are called: 

• glial cells
• mitochondria
• neurons
• nuclei

Neurons that travel toward the central nervous system are called

• afferent neurons
• efferent neurons
• exit neurons
• CNS neurons

The gap that a message has to cross to get from one neuron to the other is called the _____

• synapse
• dendrite
• axon
• synaptic cleft
