Biopsychosocial Model Flashcards
Nature and Nurture don’t work in isolation
genes and biological systems interact with life systems and mental processes
phenotype
the observed characteristics of an organism
genotype
the genes that code for the organism’s characteristics
allele
specific variant of a gene - two for each gene (one for each parent)
psychological factors are polygenic
meaning the phenotypic trait is influenced by multiple genes
diathesis stress model
this model shows that a person will inherit a risk factor that may initiate a mental illness with the interaction of specific life stressors
- an interaction with nature or nurture
gene environment correlation model
inheriting certain genes can increase the risk of experiencing negative life events
- For example, children with a genetic predisposition to behave in a self-deflating way can illicit hostile treatment from their peers
epigenetics
behavioural and environmental factors that affect the expression of genes/cellular material influencing traits
- negative habits can be genetically passed down
synapse
gap at the end of a neuron that allows signal to pass from one neuron to the next
synaptic cleft is the gap between two neuron where electrical signal is sent
reuptake
Neurotransmitters then disconnect from receptor in the synaptic cleft and go through terminal button
excitatory and inhibitory
neurotransmitters
some neurotransmitters are excitatory, increase neurons potential to fire, some are inhibitory, decrease neurons potential to fire
action potential
a neuron firing
- Activates neurotransmitters from terminal button to synaptic cleft
Nervous Systems
central nervous system
peripheral nervous system
- somatic nervous system
- autonomic nervous system
- sympathetic nervous system
- parasympathetic nervous system
- endocrine system
sympathetic nervous system
controls the fight or flight response during times of stress
parasympathetic nervous system
counteracts and calms down fight or flight responses
