Neuro_Exam 1_Basal Gang Flashcards
striatum wants to _____
inhibit GPE
GPE wants to _______
inhibit sub stalamus
subthalamus wants to ______
activate GPI
Dopamine acts on _____ to _____
D1 D2 to decrease EPI
subthalamus ______ to increase movement
activates subnigra to release dopamine to D2 or D1
D1 activated by the chemical
substance P (d block, styles p)
D2 activated by the chemical:
enkaphelin (incas-fell-in during hunting season) first neurons to die during hunting season
______ excite D2 neurons
cholinergic interneurons
_______ inhibits ach
muscarinic anticholinergic
____ is a disease involving ____ nuc lesion
hemiballisim, subthalamic nuc lesion. less appetite for Gooseberry pie (Gpi)
_____ involves death of enkaphelin
huntington’s disease
substantia nigra r____ contains _______ neurons that project to the ______
reticulata, GABArgic, thalamus and brainstem
substantia nigra c ______, contains _____ that project to the ______
pars compacta, dopaminergic, striatum
In healthy people, ______ neurons accumulate ______ giving the _____ a _____ color; in parkinsons, you see a loss of ____ showing a ____
dopamine, melanin, snc, dark, pigmentation, dopamine
_______ interneurons predominantly excite the _____, this balances the _______
cholinergic, indirect pathway, inhibitory effect of dopamine
________ can ameliorate ______ of PD
muscarinic anticholinergics, akinesia
lesions of basal ganglia causes ______, the two groups are :
dyskinesias: hyperkinetic (temor, ballism, chorea, tics) hypokinetic (rigidity, bradykinesia, akinesia)
huntingtons mnemonic:
Then hunting season caused an indirect (pathway D2) death of straight Korean (chorea) men (striatum) and it was the Incas who first fell in the trap (Enka-fell-in: first neurons to die)
parkinsons mnemonic:
In the Park where Brady kind of used to play, there seemed to be a decrease in the directions, and it all made me indirectly increased my hunger for Gooseberry Pie;
hemiballism mnemonic:
Hemi (semi) Bollywood dancer rode a unicycle up a ladder to the lama subway (subway of lamas instead of train cars) and they were no longer inhibited; This eventually caused a decreased in excitement for Gooseberry Pie (GPI)
___ and ____ are additional movement disorders
essential tremor, rigidity
______ are caused by ______ lesions and never change
rigidity, basal gang with lead pipes, and cop wheels
______ are a resistance that varies with speed, ____ deep tendon reflex, _____ tone,
spasticity, clasped knife, clonus
