AAMC Tests Flashcards
Optimal arousal theory for simple tasks
More arousal and more people leads to high performance
Optimal arousal theory for complex tasks
Bell curve for arousal
- Too low or too high arousal leads to low performance
- Need medium arousal to perform successfully
How does electrical conductivity in the skin measure arousal
Measures sympathetic arousal
-Leads to sweat which have ions in them and are conductive
General adaptation syndrome stages
Alert
Resistance
Exhaustion (if no rest period)
What is the magic number for working memory
7 plus or minus 2
Priming def
Association of something to remember something
Chunking
Breaking up something you have to remember into parts to make it easier to recall
Role strain
Difficulty performing at one specific role
Ex: my role is a student and its super hard
Role conflict
Multiple rules you’re juggling
-Hard to be between these roles
Mixed-methods study def
Combines both qualitative and quantitative studies
Gentrification def
When re-urbanization targets the wealthier community and the people who used to live there are pushed out
-Leads to greater inequality in cities
In group vs peer group
In group; who you identify with
Peer: your homies
Habituation vs dishabituation
In habituation, person tunes out the
stimulus.
Dishabituation occurs when previously habituated stimulus is removed.
What organelles do RBCs not have
No ribosomes, mitochondria, ER or nucleus
Where are endothelial cells located
Anywhere there’s vasculature
Where does bonding occur between nucleotides in DNA
Between the 5’ phosphate and the 3’ hydroxyl group
Where does bonding occur between nucleotides in RNA
Same binding
-The only difference is there’s an extra OH attached to RNA at the 2’ end
Nucleotide pnemonic for thymine
Thymine two tits
-Two carbonyl groups
Nucleotide pnemonic for for adenine
Adenine always alone above
-Only substituent (NH3) is above
Nucleotide pnemonic for cytosine
Cytosine has a heavy cock
- Drooping carbonyl
- Carbonyl groups is pointed downwards (diaganol)
Nucleotide pnemonic for guanine
Guanine gets girls with its excited erect cock
-Carbonyl pointed upwards
What is the full name of NAD+
nicotinamide adenine dinucleotide
What is the full name of FAD
Flavin adenine dinucleotide
As you move from renal cortex to renal medulla how does ionic gradient change in interstitial fluid
-What’s the context of this change
It increases
- As you move from cortex into descending loop of henle, water diffuses out to equalize solute concentration
- As you move up ascending loop of henle to the cortex, ions diffuse out
