ABC
GCS

spinal eg radiculopathy, myelopathy, which level
spinal nerve
2 MRI techniques to view neurological function
functional MRI and tractography
List some parts of the frontal lobe and their function
precentral gyrus - voluntary control of movements
pars opecularis+triangularis - speech
higher order - restraint, initiative, order
Examining frontal lobe
inspection eg urinary catheter UMN signs pronator drift saccadic eye movements speech
2 tests for restraint eg socially acceptable language
go/no go tests
stroop test
Supplementary motor cortex signs of dysfunction
lack of motivation
apathy
depression
abulia
Abulia
Inability to act decisively
Ways to examine language
hearing fluency eg brocas aphasia repetition 3 step command baby hippopotamus orofacial movement eg ppp,ttt,mmm reading and writing
