Quiz #1 Neuron Review Questions

Neuron Review #1 Label the neuron! Dendrite #1 #2 Axon #3 #4 Cell Body Myelin Sheath

Neuron Review #2 Label the reflex arc! Sensory Neuron Interneuron Motor Neuron

Neuron Review #3 Describe the reflex arc! Rubber hammer makes contact with skin of lower knee The skin’s sensory neuron sends an impulse to the spinal cord Inside the spinal cord is the interneuron, which will transport the signal to the motor neuron The motor neuron will send the impulse signal to muscle. The muscle will contract and release. The entire leg will now go through a “kicking” motion, this is the response to the initial stimulus that occurred in step #1 Neuron Review #3 Describe the reflex arc!

Neuron Review #4 Which part of the neuron is known to receive a stimulus and start a impulse in a neuron cell? #1 Dendrite #1 #2 #3 #4

Neuron Review #5 A reflex arc is illustrated in the diagram below. Structure X represents: Stimulus Response Receptor Motor neuron Interneuron Sensory neuron e. Interneuron X

Neuron Review #6 Which lists human nervous-system structures in order of increasing size? nerve, neuron, axon axon, nerve, neuron nerve, axon, neuron axon, neuron, nerve neuron, axon, nerve neuron, nerve, axon d. Axon, Neuron, Nerve

Neuron Review #7 What is the correct impulse pathway? Response  motor neuron  sensory neuron Stimulus  sensory neuron  motor neuron Reflex  motor neuron  interneuron Stimulus  sensory neuron  interneuron Response  interneuron  sensory neuron Sensory neuron  interneuron  reflex d. Stimulus  sensory neuron  interneuron

Neuron Review #8 Which part of the neuron is known to insulate and prevent impulses from “jumping” over to other neurons? #4 Myelin Sheath #1 #2 #3 #4

Neuron Review #9 Identify all of the choices that are NOT involuntary reflexes. (Identify the voluntary reactions). A baby making a grip when something touches their palm Being startled after hearing a loud sound Responding to your friend’s text Blinking your eyes when something touches your eye lashes Buckling your seatbelt Pupils dilating A boxer ducking from their opponent’s throw Knee jerk A runner hurdling over a hurdle on the track Rolling your eyes at someone C, E, G, I, J

Review Question #10 What happens to the impulse once it reaches the end of the neuron? The end of the electrical impulse signals chemical messengers to be released (neurotransmitters) so they can stimulate the next electrical impulse in neighboring neuron

1. Name that neurotransmitter… It’s late, and you are in a dark alley and hear heavy footsteps behind you. Your neurons diffuse a neurotransmitter that helps your body resist or avoid stress, fight or flight response. Melatonin Endorphin Epinephrine Serotonin Dopamine Epinephrine

2. Name that neurotransmitter… Teenagers produce this neurotransmitter later at night (compared to adults and children) and it is still produced in the morning. Some people believe this effects teens learning in school. High schools have debated starting school later for this reason. Melatonin Endorphin Epinephrine Serotonin Dopamine Melatonin

3. Name that neurotransmitter… People with depression have lower concentrations of this neurotransmitter. They have difficulty feeling pleasure and pain. Melatonin Endorphin Epinephrine Serotonin Dopamine Dopamine

4. Name that neurotransmitter… When Ms. O’Connor was in college she was required to run 12 miles with her teammates at 9am every single Sunday! It was a miserable run for Ms. O’Connor the first 8 miles, but the last 4 miles seemed to be painless and calming to her. She knew she could make it all the way. What neurotransmitter was she releasing? Melatonin Endorphin Epinephrine Serotonin Dopamine Endorphin

5. Name that neurotransmitter… Mary Jane is struggling with school and life lately, she keeps thinking over and over that she needs to clean her finger nails. The thought of microorganisms and dead skin cells underneath her nail makes her anxious. Every class she has to ask the teacher if she can go wash her hands. She brings a nail brush with her every time. Melatonin Endorphin Epinephrine Serotonin Dopamine Serotonin
