Life Support Center
How many basic food groups are there?
12
Medulla
13
Cortex that registers pain and taste
Bread, Cereal, Rice, and Pasta Group
14
Sensory cortex (in parietal lobe)
15
Part of hypothalamus that is our sleep center
Type Subject 1 400 Answer Here
16
Suprachiasmatic nucleus
17
Monitors our actions and checks for errors
Overactive in OCD patients
Type Subject 1 500 Answer Here
18
Anterior Cingulate Cortex
Type Subject 1 400 Question Here
19
Longest part of a neuron
20
Axon
Type Subject 2 100 Question Here
21
Gap between neurons
Type Subject 2 200 Answer Here
22
synapse, synaptic gap/cleft
Type Subject 2 200 Question Here
23
Three phases of neural activity
24
Resting potential action potential refractory
period
Type Subject 2 300 Question Here
25
Ions involved in the firing of a neuron
Type Subject 2 400 Answer Here
26
Sodium (NA) and Potassium (K)
Type Subject 2 400 Question Here
27
Describe the neurons biochemical activity
through all of its stages of activity
28
Starts off polarized (more negative ions inside
than outside), incoming impulse reaches the
threshold of excitation, membrane opens up,
Sodium (NA) rushes in (like a line of dominos),
neuron becomes depolarized and Potassium moves
out, a sodium-potassium pump replaces ions to
their correct place
Type Subject 2 500 Question Here
29
A type of sugar that cells need for energy As
levels drop, hunger rises
Type Subject 3 100 Answer Here
30
Glucose
Type Subject 3 100 Question Here
31
How is glucose delivered to cells?
Type Subject 3 200 Answer Here
32
Via insulin
Type Subject 3 200 Question Here
33
Hunger arousing hormone found in the stomach and
pancreas
Type Subject 3 300 Answer Here
34
Ghrelin
Type Subject 3 300 Question Here
35
Hunger arousing hormone produced by the lateral
hypothalamus
Type Subject 3 400 Answer Here
36
Orexyn
Type Subject 3 400 Question Here
37
Hormone secreted by fat cells Positively
correlated with fat stores
38
Leptin
Type Subject 3 500 Question Here
39
What does an agonist do?
Type Subject 4 100 Answer Here
40
Mimics a neurotransmitter EX morphine
Type Subject 4 100 Question Here
41
What is reuptake?
Type Subject 4 200 Answer Here
42
When the sending neuron reabsorbs recycled or
unused neurotransmitters
Type Subject 4 200 Question Here
43
How do antipsychotic meds work?
44
Thorazine acts as a dopamine antagonist
Type Subject 4 300 Question Here
45
How does botox work?
Type Subject 4 400 Answer Here
46
Botulin (in botox) works as a ACh antagonist
Type Subject 4 400 Question Here
47
Describe how SSRIs work
48
Block the reuptake of serotonin so there is more
available in the synapse
Type Subject 4 500 Question Here
49
What are the three layers of the retina?
Type Subject 5 100 Answer Here
50
Rods/cones, bipolar, ganglion cells
51
What is gustation?
52
Taste
Type Subject 5 200 Question Here
53
Where are the rods and cones located WITHIN the
retina?
54
Rods in peripheral area and cones in fovea
Type Subject 5 300 Question Here
55

What is the organ of corti?
Type Subject 5 400 Answer Here
56
On the basilar membrane inside of the cochlea,
contains the hair cells (receptor cells) for
hearing
57
What causes sensorineural deafness?
Type Subject 5 500 Answer Here
58
Damage to the cochlea or auditory nerve
Type Subject 5 500 Question Here
59
Describe a basic neural chain
Type Subject 6 100 Answer Here
60
Receptor cells change energy into an action
potential, sensory (afferent) neurons take the
message to the brain/spinal cord where it is
processed by interneurons, then motor neurons
take the message to muscles/glands
Type Subject 6 100 Question Here
61
What are sleep spindles and in what stage of
sleep are they found?
Type Subject 6 200 Answer Here
62
Bursts of brain activity Stage 2
63
What brain abnormalities are present in
schizophrenic patients?
Type Subject 6 300 Answer Here
64
Large fluid filled sacs, smaller cerebral cortex,
smaller thalamus
Type Subject 6 300 Question Here
65
What part of the brain (not the amygdala) helps
interpret emotions?
Type Subject 6 400 Answer Here
66
Insula (junction of frontal and temporal lobes)
Type Subject 6 400 Question Here
67
What are glial cells?
Type Subject 6 500 Answer Here
68
Make up the myelin sheath, hold neurons in place,
provide nourishment, remove waste products,
create the blood-brain barrier
