• Motor Neuron
• Sensory Neuron
• Relay Neuron

The nerve cell that connects sensory and motor neurons is a _______________.

• Motor Neuron
• Sensory Neuron
• Interneurons 
• Glial cells

What is the change of a cell membrane from positive to negative called?

• Glycolysis
• Action Potential
• Temporal Summation
• Electrolysis

What part of the neuron carries the impulse toward the nerve cell body?

• Dorsal Root
• Dendrites
• Myelin Sheath
• Axon

A sudden change in the polarity of the membrane of a neuron, gland cell, or muscle fiber that causes the transmission of electrical impulses

• Action potential
• Membrane potential
• Resting potential
• Threshold

The critical point at which a stimulus causes an action potential

• Synapse
• Action potential
• Membrane potential
• Threshold

A chemical substance that transmits nerve impulses across a synapse 

• Neurotransmitter
• Axon
• Synapse
• Nerve

Part of the nervous system made of the brain and spinal cord.

• central nervous system
• peripheral nervous system

What are the two parts of the nervous system? 

• The brain and spinal cord
• The central nervous and peripheral nervous system 
• The neurons and the dendrites
• The cerebrum and the medulla

This is the job of the nervous system.

• To send messages to and from the brain and spinal cord to and from the body
• To break down food to be used by the body
• To remove wastes from the body
