Neurologic assessment Flashcards
Neuron
basic functional unit of the brain; dendrite, cell body, axon
neurotransmitters
acetylcholine, serotonin, dopamine, norepinephrine, endorphins
acetylcholine
neurotransmitter of the parasympathetic nervous system; important in MS
serotonin
helps control mood and sleep, pain pathway (think psych meds)
dopamine
affects behavior (emotions, attention), fine movement (parkinsons)
norepinephrine
major transmitter of the sympathetic NS
endorphines
produced by hypothalamus; pleasurable sensation, inhibits pain transmission
cerebrum
frontal lobe, parietal lobe, temporal lobe, occipital lobe,
frontal lobe
concentration, abstract thoughts, memory, affect, judgement, and inhibition ; brocas area
brocas area (frontal lobe)
located on the left hemisphere; speech center
singing uses different lobe!!
parietal lobe
sensory lobe; function is right and left orientation, shape discrimination
temporal lobe
auditory memory of a sound, understanding of language and music ; recognition of friends
occipital lobe
visual interpretation and memory
brain stem
composed of midbrain, pons, medulla, oblongata
function of brain stem
reflex center for respiration, blood pressure, HR, coughing, swallowing;
damage to brainstem can lead to immediate cessation of breathing (immobilize head)
