1. Prompt #9
How do you think the brain communicates with its structures and with the rest of the body?

2. Pg
The Nervous System

3. Candy Neuron
Build ONE neuron with the supplies (diagram in book shows two – be careful!)
You have extra supplies, but DO NOT EAT UNTIL YOU CHECK IN YOUR NEURON
Be able to describe how an impulse travels through each structure of your neuron
Use the notes you just took
Check in with me (WILL HAVE TO EXPLAIN)
Draw and label a neuron on sheet with impulse direction included

4. Neuron
*Missing: synapse
axon terminal
neurotransmitters

5. Draw and label a neuron using the following features:
Prompt #4
What is a neuron?
Draw and label a neuron using the following features:
nucleus, dendrites, axon, neurotransmitters, synapse, cell body, axon terminal, myelin sheath

6. Neuron
*Missing: synapse
axon terminal
neurotransmitters

7. The Nervous System Controls the body Broken into:
Central Nervous System (CNS)
Peripheral Nervous System (PNS)

8. How does information travel through the N.S.?
Sends signals (chemical & electrical)
Electrical—throughout the neuron
Chemical—neurotransmitters

9. Electrical Impulse

10. Important Functions Nucleus: Cell Body: Myelin Sheath:
Holds genetic info
Cell Body:
Creates proteins
Myelin Sheath:
Speed up electrical impulses
Protect the axon

11. Neurotransmitters Chemicals produced in the cell
Control  heartbeat, digestion, mood, sleep, concentration, weight
Released and have two options:
Info is passed to new cell (transmission) or it stops (inhibition)

12. Neurotransmitters Neurotransmitter Affects Serotonin
Mood, certain processes (sleep, pain, digestion)
Dopamine
Focus, motivation
Acetylcholine
Movement, memory
Norepinephrine
Anxiety, energy, sleep problems, focus
Epinephrine
Heart rate, blood pressure

13. Neurotransmitters (cont.)
Affected by: stress, diet, toxins, genetics, drugs, alcohol, and caffeine
Oversupply or undersupply has been linked to diseases:
Oversupply
Acetylcholine  Alzheimer’s
Dopamine  schizophrenia
Undersupply
Dopamine  Parkinson’s
Serotonin  depression

14. Current Article on the Brain

15. Write down one takeaway from their article on back of your assignment
Articles
Write down one takeaway from their article on back of your assignment
Must talk to 3 people; 5 if you do not have an article to share

16. Brain/Neuron Structure Practice
With your group, you must represent each structure we have covered (11 total)
One color = cerebral cortex (divide into structures with lines)
One color = inner structures/corpus callosum
Check your brain in with me when completed!
Then construct a neuron! Check in when done as well!

18. Review Stations Brain functions worksheets Labeling & flash cards
Take one or both worksheets
Check answers with a few minutes remaining
Labeling & flash cards
Mnemonics/memory strategies
Autonomic Nervous System = Automatic/Involuntary actions (i.e. breathing)
Hippocampus = school campus (spatial navigation and knowing the layout in your mind)
Corpus Callosum Communicates TWO halves
