biopsychology Flashcards
function of frontal lobe
voluntary movement, expressive language, managing executive functions.
where is the parietal lobe? function?
top of brain
sensory info
occipital lobe function
visual perception
temporal lobe function? where is it found?
processing emotions, understanding language, memory
found between brain stem and frontal lobe
what 2 divisions is the nervous system split into?
peripheral nervous system and central nervous system
what is the pns split into? what are their functions?
somatic nervous system: responsible for all the functions we know and can consciously influence
autonomical nervous system: regulates involuntary physiologic processes
what are the effects of the sympathetic nervous system?
decrease saliva production
increase heart rate
inhibits digestion
inhibits bladder contraction
pupils dilate
what are the effects of the parasympathetic nervous system?
increase saliva production
decrease heart rate
digestion
bladder contraction
pupils contract
first 3 stages of fight/flight
1.enter danger
2.amygdala activated, signals hypothalamus
3.hypothalymous activates sam pathway medulla-sns
last 3 stages of fight/flight
4.sns stimulates the adrenal medulla part of adrenal gland
5.adrenal medula secretes hormones adreniline + noradrenaline
6.adrenaline stimulates physiological change for fight/flight
thyroid gland function
to produce hormones that help regulate the body’s metabolism
pituitary gland function
master gland
controls release of all other hormones in the body
endocrine system
a network of glands across the body that secrete chemical messages called hormones, slower and longer lasting than nervous system
sensory neurone function and structure
carries messages from pns to cns, long dendrites and short axons, if nerve signals reach the brain they are translated to senses if not they are involved in a reflex arc
relay neurone function and structure
connect sensory and motor neurones. short dendrites and short axons
motor neurone function and structure
connects cns to muscles and glands, short dendrite long axons, when stimulated release neurotransmitters which trigger a response
