Nervous System Test 1

The basic structural unit of the nervous system:

• nerve

• neuron

• brain

• spinal cord

What part of the neuron receives the message from the previous neuron?

• Terminal Fibers
• Dendrites
• Cell Body
• Myelin

What part of the neuron can be described as a tail like structure that carries the impulse away from the cell body?

• Axon
• Cell Body
• Dendrites
• Synapse

Label the Neuron-What does the letter "H" represent?

• Schwann Cell
• Axon
• Axon Terminal
• Dendrite

a junction at which a neuron meets another cell

• axon
• dendrites
• myelin sheath
• synapse

Label the Neuron-What does the letter "A" represent?

• Axon
• Dendrite
• Axon Terminal
• Cell Body

Neuroglia that produce myelin on axons in the peripheral nerves are

• schwann cells

• astrocytes

• oligodendrocytes

• microglia

The part of the neuron that insulates the axon and increases the speed of the neural message within the neuron.

• Synapse
• Dendrite
• Myelin Sheath
• Axon Terminal Button

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
