Neuron Structure

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

• axon 
• dendrite
• axon terminal
• gene

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

A chemical produced by neurons that carries messages to other neurons

• myelin sheath
• neurotransmitter
• axon
• axon terminal

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

Which is the following is represented by the letter B?

• cell body

• nucleus

• dendrite

• axon

Which is represented by the letter E?

• Axon

• Myelin sheath

• schwan cells

• terminal branches

Impulses that travel down a myelinated neuron move faster than if it was unmyelinated.

• True
• False
• I'm not sure

_____ neurons carry messages to the central nervous system

• Motor
• Inter
• Sensory
• Fun

What is the nerve impulse in the axon called?

• action potential
• resting potential
• membrane potential
• synapse
