Outline 16 Brain Matter

Question 1

The brain is mostly ________ matter

Answer 1

gray

Question 2

Gray mater is made of

Answer 2

-Neuron cell bodies

they are the basic building blocks that are designed to reach many cells in an interaction

Question 3

Broca’s AREA & Wernicke’s AREA means that cells do what here?

Answer 3

an area of cells

Question 4

Gray matter is ________ neurons and axons

Answer 4

Unmyelinated neurons & axons

Question 5

What are neurons?

Answer 5

oBasic building block
oFunctioning, receive, transmit, synthesis information
“sending messages on” part of the brain
oNeurons consists of cell body (metabolism), dendrites, and a single axon

Question 6

What are the parts of a neurons ?

Answer 6

oNucleus, cytoplasm, organelles
oHave many dendrites, but 1 axon
o A cell body (metabolism), dendrites, and a single axon

Question 7

What does it mean that we have many dendrites, but 1 axon

Answer 7

This means we can take in a lot of information but only put out so much

Question 8

What is synthesis?

Answer 8

Memory

• Relating one piece of information to another
• Absolutely the foundation of language and learning

NOTE: We don’t understand synthesis

Question 9

The sensory and integrator aspect is so important for _____

Answer 9

neurons

Question 10

Dendrites have many branches (dendritic spine) but only has one axon. What does that mean?

Answer 10

The sensory and integrator aspect is so important for

Question 11

When does massive dendritic spine development occur?

Answer 11

at 2 years old and prunes at puberty

it gets ride of little used pathways and maintains the frequently used pathways

Question 12

T/F you are born with the # of neurons you will always have

Answer 12

true unless you binge drink

Question 13

the brain is a ____ ______

Answer 13

pattern seeker

Brain becomes accustomed to certain behaviors, and languages

Question 14

What is pruning?

Answer 14

Combo of dendrites losing spines – pruning of the brain at puberty & occasionally neurons dying off

Question 15

What are dendrites responsible for

Answer 15

incoming info

-just receiving

Question 16

T/F Intellectual disability are accompanied by faulty dendritic spine

Answer 16

true

Question 17

what are axons responsible for?

Answer 17

outgoing info
•Structure that interacts at the synapse
•Actively sending and transmitting messages to other neurons through the terminal bouton

Question 18

what is white matter?

Answer 18

Mylinated

•Mylinated neurons move info faster and more direct from one place to another

Question 19

What moves info faster myelinated or un?

Answer 19

Mylinated neurons move info faster and more direct from one place to another

Question 20

What can synapse with what?

Answer 20

• Dendrites synapses with axons and other dendritic spines

* Axons synapse with dendrites; not another axon

Question 21

The electrochemical message crosses and synapses where?

Answer 21

Axon through the terminal bouton is sending electrochemical message across the synapse

Question 22

The end of the Axons contain multiple vesicles (storage sites) for ___________

Answer 22

neurotransmitters between the end of one axon dendrite of another

Question 23

what are Neurotransmitters?

Answer 23

oChemical soup that govern everything we think and do

oNeurotransmitters: Dopamine, serotonin, ATP, Gaba

Question 24

which cells are structural?

Answer 24

Glia cells
• Holding neurons together

o	Think of them as scaffolding
o	Support and protection
o	Astrocytes
o	Dendrocytes
o	Microglia

Question 25

when talking about White-matter Pathways a bundle of fibers travels to other parts of the brain. This electrochemical connections have various names. Name them…

Answer 25

Fascicles
o Individual fiber
o It is a axon

Fasciculus
o Bundle of fibers

Funiculus
o Bundle of fasciculus

Question 26

Pathway to get information from one area of the brain to another area of the brain. Name 3 big white matter pathways

Answer 26

Column
Lemniscus
Peduncle
