stress
3 marks
a psychological + physiological/ biological response
to internal or external sources of tension
that challenge a person’s ability to cope
stressor
4 marks
a person
situation or
event that
produces stress
chronic stress
2 marks
stress that occurs due to an
ongoing
long-term stressor
characteristics of chronic stress
3 marks
- stress response is less severe/intense
- stress reponse is longer lasting
- recovery can take longer due to the ongoing problems.
side effects of chronic stress
4 marks
- weakening of the immune system
- disruptions to the digestive + reproductive system
- increased risk or heart attack/ stroke
- increased vulnerability to mental health issues. (depression)
disadvantages of the exposure of coritsol to chronic stress
4 marks
- strains/damages internal organs and tissues
- puts you ata greater risk for things like heart disease
- weakens the body’s immune system
- makes you more vulnerable to bacteria and viruses that cause diseases.
gastrointestinal tract (gut)
2 marks
passageway of the digestive system
from the mouth to the anus
gut-brain-axis (GBA)
4 marks
connection that exists between the enteric nervous system (ENS)
and central nervous system (CNS)
it enables the bidirectional (two-way) communication between the brain and the gut
two ways the Enteric nervous system (ENS) and central nervous system (CNS)
2 marks
vagus nerve
gut microbiota
vagus nerve
2 marks
connects the brain stem to organs within the autonomic nervous system
relation between ENS and vagus nerve
4 marks
vagus nerve carries sensory information from the gut to the brain
vagus nerve carries motor information from the brain to the gut
functions of gut microbiota
4 marks
- assists in the digestion of food to provide us with energy + nutrients
- production of neurotransmitters such as:
GABA
serotonin (90% found in gut)
dopamine - regulation of immune system functioning
- INFLUENCING PSYCHOLOGICAL PROCESSES + BEHAVIOUR
key findings from emerging research on the bidirectional link between gut microbiota and stress.
4 marks
- exposure to chronic stress (associated with prolonged release of cortisol) can change our gut microbiota composition
- composition of our gut microbe population can shape our responsiveness to stress
- treatment with ‘healthy’ gut microbiota can reduce stress responsiveness
emerging research on gut microbiota show that it influences…
4 marks
- stress responsiveness
- anxiety
- depression
deficiences in gut microbiota = higher chance of anxiety and depression
