25
kidney
filters blood
26
testes
sperm
27
thalamus
sending messages
28
adrenal gland
adrenaline
29
gonads
sex organs
30
acetylcholine (ACh)
enables muscle action, learning, memory
31
dopamine
pleasure. influences movement, learning, attention, and emotion.
32
serotonin
happiness
33
norepinepherine
adrenaline. Helps control alertness and arousal. Undersupply can depress mood.
34
GABA (gamma - aminobutyric acid)
Inhibitory neurotransmitter (slows things down)
35
Glutamate
Excitatory neurotransmitter, involved in memory.
36
endorphins
natural painkillers
37
Neurotransmitters
Chemical that travels through neuron
38
Reuptake
After neuron has taken neurotransmitter, any remaining chemicals are re-absorbed by the sending neuron
39
Lock and Key Mechanism
when the sending and receiving neurons are identical
40
Agonist
The neurotransmitter is close enough to a match that a neuron accepts it
41
Antagonist
Blocks neuron from accepting the neurotransmitter
42
Nerves
Multiple neurons
43
Glial cells
aka glue cells, support, nourish, and protect neurons
44
Hypothalamus
Sex, hunger, thirst
45
Visual agnosia
When you fail to recognize objects, persons, or color
46
Face blindness
Inability to recognize people’s faces
47
Association Area
Parts of the brain that are unknown
48
Plasticity
Brains ability to modify itself after some type of injury or illness
49
Corpus Callosum
connects both hemispheres, where seizures happen
50
In what disease is PCh low?
Alzheimer’s
51
Excess dopamine leads to what disease?
Schizophrenia
52
Too little dopamine is linked to what disorder?
Parkinson’s
53
Under supply of serotonin leads to what?
Depression
54
Too little GABA leads to what?
seizures, tremors, and insomnia.
55
Too much glutamate linked to…
migraines and seizures
56
aphasia
impairment of language caused by damage to Broca's area of Wernicke's area
57
sympathetic
spends energy
58
parasympathetic
mends energy
59
Electroencephalogram (EEG)
detects electrical activity in neurons
60
Magnetoencephalography (MEG)
records magnetic fields from brains
61
CT scan
generates images to locate brain damage
62
MRI
to visualize brain structure
63
fMRI
an MRI while the person is doing a task
64
Broca's Area
producing speech
65
motor cortex
moving muscles
