NURS 126 EXAM # 1
Cerebrum - answer4 lobes that control sensory/motor fx and higher level thinking
abilities
limbic system includes what 4 things ("emotional brain") – answer hippocampus,
amygdala, hypothalamus, and thalamus
changes in the limbic system puts pt's at risk for - answer stress, addiction, and other
stress related disorders.
pasticity - answerthe brain's ability to change and adapt to problems to be able to
function
what drugs slow the limbic system? - answerantianxiety
extrapyramidal motor system (EPS) - answerdopamine is a neurotransmitter important
to the EPS to maintain proper muscle tone/stability.
what meds are based on dopamine - answerantipsychotic meds
basic vital life functions occur in the brainstem, but what is it made of? -
answermidbrain, pons, and medulla
Reticular Activating System (RAS) - answerthru the brainstem a persons consciousness
and sleep-wake cycle is set
cerebellum provides both... - answerintellectual/cognitive functioning and motor control
the thalamus act like a filter for what - answersensory information
disruption in the thalamus function is associated w/ ... - answerschizophrenia
hypothalamus regulates - answerbody temperature, hunger, thirst, and water and
electrolyte balance, circadian rhythms, corticotropin releasing hormones
what hormones are secreted by the hypothalamus under stressful conditions? -
answercorticotrophin releasing hormones
HPA axis - answerhypothalamic-pituitary-adrenal gland cycle involved in maintaining
homeostasis in all organ systems
, hypothalamus sends messages to what (also whats it made of) - answerautonomic
nervous system. made up of Sympathetic/Parasympathetic
sympathetic nervous system - answerfight or flight (REVS BODY BACK UP)
parasympathetic nervous system - answerbrings body back down
Neuroimaging - answermethod of visualizing the brain that allows us to see how
different structures are shaped/formed and how they interact with one another
structural imaging (3) - answerCT (taken in slices/3D)
MRI (magnet/radio field waves)
functional MRI (blood flow)
functional/some activity imaging (2) - answerPET (radioactive substance injected and
shows up bright/3D)
SPECT (like PET but uses photons, less $)
cells in our brain are called - answerneurons
more than........ neurons in the brain - answer100 billion
How do neurons communicate? - answerthey have chemical messengers and conduct
electric impulses which they use at the gap between each cell.
gaps between neurons are called - answersynapses
where do messages from neurons get released? - answersynapses
sending messages between neurons is like what method - answerkey and lock
enough chemical messenger
enough receiver
and nothing interfering
the reuptake is - answera process by which neurotransmitters are sucked back into the
neuron for storage after sending a message
Monoamines neurotransmitters - answernorepinephrine, dopamine, serotonin,
acetylcholine
