extrapyramidal tracts - spinal cord | conduction plays a crucial part in producing large automatic movements and emotions |
motor program | set of coordinated command that control the programmed motor activity mediated by the extrapyramidal pathways |
ccerebrovascular accident | AKA stroke, disruption of blood flow through the cerebral vessels, decreased oxygen supply to brain tissue |
cerebral palsy | perm, non progressive image to motor control areas of the brain, usually present at birth, most common cause is due to lack of oxygen to the brain, can be caused by head trauma at birth, prenatal infections, or poisons |
dementia | degenerative processes that cause destruction of neurone in the brain, can affect memory, attention span , intellectual, capacity, personality, motor control |
Alzheimers disease | a form of dementia occurring in middle to late adulthood, thought to be a genetic disorder, lesions the toccur are called amyloid plaques and neurofibirlity tangles |
Huntington's disease | inherited chorea (purposeless movements) that causes dementia, beginning around age 30-40 death occurs by age 55, abnormal protein huntingin prevents normal brain function |
parkinsons | degeneration of the substantial migration and the dopaminergic neurone house in the basal ganglia, there is a decreased production and secretion of dopamine- needed to produce smooth controlled movements.
symptoms are tremors, rigidity, bradykinesia, postural instability |
seizures | sudden bursts of abnormal neurone activity that result in ten changes in brain function |
epilepsy | recurring, chronic seizure episodes, considered idiopathic, treated with anticonvulsants, diagnosed and evulatated based on EEG readings |
