behavioral sciences Flashcards
three types of neurons in nervous system are
motor ie efferent, interneurons, and sensory ie afferent
major nerves of ps branch
vagus and pelvic splanchnic nerves
shit parasymp does
constril pupils, stimulate flow of saliva, constrict bronchi, slow heartbeat, stim peristalsis, stim secretion, stim bile release, contract bladder
shit symp does
secretion of adrenaline and noreadrenaline
accerelate heartbeat
piloerection or sweating
inhib digestion
stim glucose production and release
stim orgasm
dilate pupiles, bronchi, bladder
organization of brain
hindbrain, midbrain, forebrain
hindbrain contains
cerebellum, medulla oblongata, reticular formation
midbrain contains
inferior and superior colliculi
forebrain includes
thalamus, hypothalamus, basal ganglia, limbic system, cerebral cortex
parts of forebrain
thalamus, hypothalamus, basal ganglia, limbic system
what the thalamus does
relay station for sensory info
what the hypothal does
maintains homeostasis and integrates with endocrine system through hypophyseal portal system which connects it to anterior pit
what basal ganglia does
smoothens movements and helps maintain postural stability
what limbic system does
controls emotion and memory
shit limbic system includes
septal nuclei, amygdala, hippocampus, fornix
what septal nuclei are about
pleasure-seeking
what amygdala is about
fear and agression
what hippocampus is about
memory
what fornix is about
communication with limbic system
lobes of cerebral cortex
frontal, parietal, occipital, temporal
function of frontal lobe
executive function, impulse control, long-term planning, motor control, speech production
subdivisions of frontal lobe
prefrontal cortex, primary motor cortex, Broca’s area
prefrontal cortex
long-term planning
primary motor cortex
motor function
broca’s area
speech production
occiptal lobe
visual processing
temporal lobe includes
auditory cortex, wernicke’s area, limbic system
auditory cortex
sound processing
Wernicke’s area
speech perception
limbic system
emotion and memory
where brain shit is
acetylcholine is for
volutnary muscle control, PS nervous system, attention, alertness
what epi and norepi do
fight or flight, wakefulness, alertness
what dopamine does
smooth movements, postual stability
serotonin
mood, sleep, eating, dreaming
GABA, glycine
brain stabilization
glutamate
brain “excitation”
endorphins
natural painkillers
