UNIT 3 Basics of the Nervous System LESSON 1 The Neuron
Match the description that most accurately describes each term.
Action potential - The reversal of the electrical potential in the plasma membrane of a neuron
Interneuron - A type of neuron that sends information between sensory and motor neurons
Axon - Long fibers that carry signals away from the cell body
Efferent neuron - A type of neuron that sends information away from the central nervous system to muscles or glands
Myelin sheath - The fatty material surrounding some axons
Afferent neuron - A type of neuron that sends information from the sensory receptors toward the central nervous system
Synaptic cleft - The space between two cells
Neurotransmitter - A type of chemical released from the tip of an axon into the synaptic cleft when a nerve impulse arrives
Node of Ranvier - Gaps in the myelin sheath
Dendrite - Short, highly branched fibers that carry signals toward the cell body
5/5 Have a nice day! :)
Great job! You matched all the terms correctly. Have a nice day too! :)
Dude, thank you so much! The quizlet was missing a lot :p
Thanks for the 100% :D
You're welcome! I'm glad I could help fill in the missing information for you. Congratulations on getting a perfect score! If you have any more questions or need further assistance, feel free to ask. Keep up the great work! :)

3. Axon - Long fibers that carry signals away from the cell body
4. Efferent neuron - A type of neuron that sends information away from the central nervous system to muscles or glands
5. Myelin sheath - The fatty material surrounding some axons
6. Afferent neuron - A type of neuron that sends information from the sensory receptors toward the central nervous system
7. Synaptic cleft - The space between two cells
8. Neurotransmitter - A type of chemical released from the tip of an axon into the synaptic cleft when a nerve impulse arrives
9. Node of Ranvier - Gaps in the myelin sheath
10. Dendrite - Short, highly branched fibers that carry signals toward the cell body
Well done! Feel free to ask any more questions or if you need further clarification. Have a nice day too!
To match the descriptions and terms accurately, follow these steps:
1. Action potential: The reversal of the electrical potential in the plasma membrane of a neuron.
- Look for the description that mentions the reversal of electrical potential.
- Match it with "Action potential."
2. Interneuron: A type of neuron that sends information between sensory and motor neurons.
- Look for the description that describes a neuron's role in transmitting information between sensory and motor neurons.
- Match it with "Interneuron."
3. Axon: Long fibers that carry signals away from the cell body.
- Look for the description that mentions long fibers carrying signals away from the cell body.
- Match it with "Axon."
4. Efferent neuron: A type of neuron that sends information away from the central nervous system to muscles or glands.
- Look for the description that describes a neuron's role in transmitting information away from the central nervous system to muscles or glands.
- Match it with "Efferent neuron."
5. Myelin sheath: The fatty material surrounding some axons.
- Look for the description that clearly defines the fatty material surrounding some axons.
- Match it with "Myelin sheath."
6. Afferent neuron: A type of neuron that sends information from the sensory receptors toward the central nervous system.
- Look for the description that describes a neuron's role in transmitting information from sensory receptors toward the central nervous system.
- Match it with "Afferent neuron."
7. Synaptic cleft: The space between two cells.
- Look for the description that mentions the space between two cells.
- Match it with "Synaptic cleft."
8. Neurotransmitter: A type of chemical released from the tip of an axon into the synaptic cleft when a nerve impulse arrives.
- Look for the description that describes a chemical released from the tip of an axon into the synaptic cleft.
- Match it with "Neurotransmitter."
9. Node of Ranvier: Gaps in the myelin sheath.
- Look for the description that mentions gaps in the myelin sheath.
- Match it with "Node of Ranvier."
10. Dendrite: Short, highly branched fibers that carry signals toward the cell body.
- Look for the description that describes short, highly branched fibers carrying signals toward the cell body.
- Match it with "Dendrite."
By following these steps, you can accurately match the descriptions with each term. Good luck!
