Quizplus · Accepted Answer

The pathway that degenerates in Parkinson's disease is the substantia nigra to caudate nucleus and putamen pathway, which is part of the basal ganglia system. This pathway is responsible for controlling and coordinating movements, and its degeneration leads to the motor symptoms seen in Parkinson's disease. The cerebellum pathway and the cerebral cortex pathway are not directly involved in Parkinson's disease.
