Neurological Assessment Flashcards
cerebellum
80% of brain tissue, has 2 hemispheres divided into 4 lobes
frontal lobe
intelligence, abstract, emotions, judgement
parietal lobe
size, texture, touch, pressure, pain, language receptors (broca, werniche )
broca
regulates verbal expression and writing ability
werniche
integrates understanding of spoken or written words
expressive dysphasia
understand but cannot respond
receptive dysphasia
do not understand
occipital lobe
vision
temporal lobe
memory, auditory input
limbic
primitive responses, body on survival mode, responsible for breathing
diencephalon
houses thalamus and hypothalamus
thalamus
major relay station for motor and sensory stimuli
hypothalamus
controls vital functions (temperature, heart rate, blood pressure, sleep, autonomic nervous system, emotions)
brainstem
medulla, pons, midbrain
medulla
ascending/descending nerve track between brain and spinal cord, CN 3-12
pons
“bridge” connects spinal cord w/ brain and parts of brain to sensations, injury to pons may have abnormal eye movement and/or biots breathing (rapid, pause)
midbrain
regulate vision, hearing, and other reflexes (like focusing and pupil dilation)
how many cranial nerves are there
12
myelination
covering, transfer signals cleanly, doesn’t really develop until age 2
demyelimination
develop numbness and may be unable to pick up objects
multiple sclerosis (MS)
can’t do fine/gross motor skills
seizures
rapid impulses across derolrites to next neuron
