Everything I forgot Flashcards
pshhhh (22 cards)
Spinal Cord
Is the spinal reflex
Carries sensory information to the brain and motor information away from the brain
Arousal
The sympathetic nervous system increases your arousal
GABA
Counteracts the excitatory activity of glutamate by slowing down or inhibits neural activity, enabling neural pathways to be balanced
Glutamate
Is associated with the learning and naming process as it is excitatory.
Stimulates activities in a neural pathway, and promotes a strengthening of the synapses within it.
Serotonin
Low levels of serotonin in the brain increases aggressive and violent behaviours
Neuromodulators
Strengthen or alters the effectiveness of neural transmissions by controlling the amount of neurotransmitters produced
Long term potentiation
Permanent strengthening of synaptic connections due to repeated activity, speeds up communication
Psychological
Includes feelings such as fear, excitement and thoughts such as ‘I can’t cope’
Biological/physiological
Includes physical responses such as increase heart rate and increase muscle tension
Cortisol
- Produced and released by adrenaline glands
- Regulates metabolism
- controls blood sugar levels
Acute stress
Is short term and often more intense and immediate responses and isn’t prolonged
Biological model of stress
GAS
Shock
Acute stress response
Counter shock
Fight-flight-freeze
Adrenaline and cortisol initially being released
Muscles tense, heart rate and breathing rate increases
Resistance stage
- Cortisol levels are at their highest
- Increased energy levels because of the effect of Cortisol
- Immune system functioning impaired
Exhaustion stage
- Bodies resources are depleted
- No longer manage everyday tasks
- Susceptible to serious illness, chronic diseases
Coping flexibility hypothesis
Richer coping flexibility produces more adaptive outcomes caused by stress responses, such as reduced psychobiological functions
ENS
controls the digestive system
Gut microbiota
- Healthy balance can maintain your stress
- Stress has a negative impact on your gut microbiota
- Gut microbiota must be well-balanced in order to be considered a healthy gut
Cortisol
Increased levels of cortisol can effect the results of changes in your gut microbiota
Gut brain axis
Refers to the brain and the gut being connected via several means including the vagus nerve
Bidirectional
Communication can occur in both directions, meaning that the brain and gut can influence each other
