Transmission of Nerve Impulses

Fat covering that increases the rate of transmission and insulates the axon:

• axon

• dendrite

• myelin sheath

• schwann cell

Special chemicals which allow the impulse to jump across the synapse to pass to another neuron:

• neurotransmitters

• schwann cells

• myelin sheath

• nerves

Which is represented by the letter H?

• axon

• myelin sheath

• schwan cell

• axon terminal

The basic structural unit of the nervous system:

• nerve

• neuron

• brain

• spinal cord

Nerve fibers in the neuron that carries impulses toward the cell body:

• axon

• dendrite

• nucleus

• myelin sheath

The space between neurons:

• neurotransmitter

• synapse

• terminal branches

• schwann cells

What is the tiny space called where impulses are transmitted from one nerve cell to the adjacent one?

• Dendrite

• Axon

• Synapse

• Neuron

Which part of the nerve cell does the impulse enter through?

• Synapse

What triggers the release of a neurotransmitter at a synapse?

• Impulse

• Synapse

• Neuron
