muscle types

smooth, cardiac, skeletal

1 of 8

muscle act is monitored by 2 key proprioceptors

1)muscle spindles 2)golgi tendon organs

2 of 8

modulation

eg-withdrawal reflex (hot dish)

3 of 8

cortical control of movement

PPAC ,DPAC, SMC, PMC

4 of 8

descending pathways (dorsolateral)

Dorsolateral corticospinal tract, Dorsolateral corticorubrospinal tract, Ventromedial corticospinal tract, Ventromedial corticobrainstemspinal tract

5 of 8

Parkinsons disease

degeneration of Da neurons connecting substantia nigra with striatum of BG (nigrostriatal pathway) -abnormal accumulation of alphasynuclein in Da cells (lewy bodies)

6 of 8

PD treatment

-L-Dopa -fetal tissue transplant -lesioning/deep brain stim

7 of 8

Huntingtons disease

dengeneration of BG nuclei (caudate nucleus and putamen) -inhibitory GABAergic neurons in BG are affected -inherited-mutation of gene on chromos 4-protein it produces(huntingtin) is abnormal
