    Cards (33)

    • genotype - physical and behavioural characteristics
    • phenotype - expression of characteristics
    • twin studies - mz and dz twins compare concordance
    • concordance - liklihood of developing characteristic if twin has it
    • diathesis stress - enviornemntal stressor and genetic vulnerability
    • evolution - development of successsive generations of natural organisms due to adaption to environement
    • natural selection - darwin - survival of fittest
    • inherited characteristics - physical or behavioural
    • endocrine system - chemcial messaging system through body that releases hormones
    • pituitary gland - master gland - controls release of hormones in other glands
    • adrenal gland - releases adrenaline - fight or flight response
    • reflex arc - collection of cells that transmit info from source and make response happen
    • sensory - send info from other senses to brain
    • relay - connect with other neurones interpreting meanign and response
    • motor neurones - send mesages from brain to muscles
    • synapse - action potential travels down presynaptic - vesticles release neurotransmitter into synpatic cleft - neurotransmitters detected
    • neurotransmitters - chemcial messagers - onhibitory or exhitatotry
    • summation - net effect of inhibitory of excitatoy influences
    • ns - coollection of nerve cells accross the body
    • peripheral nervous system - collection of nerve cells accross the body
    • cns - brain and spinal cord
    • brain stem - regulates basic functions like heartrate
    • cerebellum - recieves info from sensory systems
    • cerebral cortex - largest area of brain - skin layer
    • occipital lobe - visual stimuli
    • parietal lobe - regulates sensory info
    • temporal lobe - aiditory perception
    • frontal lobe - predicts future consequences
    • cons - biological determinism
    • cons - biologicla reductionism
    • cons - nature only
    • pro - objective
    • pro - practical application to drug therapy
