A specialized cell that transmits information throughout the body is called a 

• dendrite
• axon
• neuron
• myelin sheath

This part of the neuron receives information from other neurons.

• dendrite
• axon
• nerve
• myelin sheath

This is a long extension of cytoplasm that conducts nerve impulses along a neuron

• dendrite
• axon
• nerve
• myelin sheath

A bundle of neurons is called a

• dendrite
• axon
• nerve
• myelin sheath

This is a fatty outer layer which insulates the neuron allowing the electrical impulses conducted to move faster by jumping

• neuron
• dendrite
• axon
• myelin sheath

An action potential is a nerve impulse that can be described as a local _ of polarity inside a neuron.

• reversal
• increase
• elimination
• superimposition

The first step in the conduction of a nerve impulse is

• the neuron at rest has a negative resting potential
• a stimulus causes the sodium ion channel to open
• the resting potential is fully restored
• the potassium channels open

Which is the last step in the synaptic transmission of a nerve impulse from pre-synaptic neuron to a postsynaptic cells.

• a nerve impulse arrives at the axon terminal of the presynaptic cell
• vessicles in the presynaptic neutron fuse with the cell membrane
• neurotransmitter molecules are released into the synaptic cleft
• neurotransmitters bind to receptor proteins on the postsynaptic cell

The parts of the CNS are 

• brain and spinal cord
• sensory and motor neurons
• sensory neurons and spinal cord
• brain and motor neurons

Your peripheral nervous system consists of 

• motor neurons
• sensory neurons
• motor and sensory neurons
• brain and spinal cord
