Parts of a Neuron
Dissection/Other
100
The central nervous system is made of these parts
brain and spinal cord
100
The primary cell that builds all the structures of the nervous system
Neuron
100
The dark blue part is the:
Brainstem
100
The soma contains what? (Hint: It's a cell part that we learned in unit 1)
Nucleus
100
Name a similarity between human and sheep brains.
Similar shape, same basic 3 structures, lobes are in the same spots, lobes have the same functions
200
What connects the brain to the spinal cord?
Brainstem
200
What is the difference between a sensory and motor neuron?
Sensory - carried to brain, processes sensory/external stimuli & information
Motor- carried from the brain to nerves/muscles/body, control voluntary movement
200
The teal, pink, green, and yellow parts of this diagram all make up what part of the brain?
Cerebrum
200
What is the name of the long, middle "tube" of the neuron that connects each end?
Axon
200
Name a difference between human and sheep brains.
Human's frontal lobe is bigger, sheep have a smaller cerebrum & smaller brain overall, sheep have a bigger olfactory bulb, sheep have a horizontal brainstem & humans have vertical
300
What major part of the brain helps with balance and coordination?
The cerebellum
300
What is the function of the frontal lobe in the brain?
Decision making, complex thinking, problem solving, voluntary movement
300
The red part is the:
Cerebellum
300
What is the fatty covering of the axon that helps impulses travel quickly?
Mylein sheath
300
Name an example of a positive feedback loop.
Giving birth, vomiting, sneezing, blood clotting
400
What is the name for the brain's outer protective layer of tissue?
Meninges
400
What is the purpose of interneurons in the brain and spinal cord?
Connect sensory and motor neurons
400
The branch-like extensions on the left side of this photo are called what?
Dendrites
400
What is the function of dendrites?
To receive nerve impluses
400
What was the purpose of the Zombie Brain lab?
To create a drug that uses neurotransmitters to target regions of the brain and modify behavior/body functions
500
What is included in the peripheral nervous system?
All nerves that branch off from the spinal cord.
500
What is the function of the occipital lobe?
vision
500
The yellow portion of this image is showing what?
Axon (also could technically be the myelin sheath)
500
What is the name of the space between dendrites and axon terminals? (They exchange neurotransmitters!)
synapse
500
Why do we have folds and grooves in the brain?
increase surface area, more space for neurons & more complex brain
