Final answer:
Parkinson's disease is caused by the degeneration of dopamine neurons in the substantia nigra. While acetylcholine is involved in the pathology of Parkinson's disease, too much acetylcholine actually inhibits the Basal Ganglia and can alleviate Parkinsonian symptoms.
Step-by-step explanation:
Parkinson's disease is caused by the degeneration of dopamine neurons in the substantia nigra. This leads to an imbalance in neurotransmitters in the basal ganglia circuitry, particularly an increased excitation in the Substancia Nigra, resulting in tremors, slowed movement, and other symptoms. While acetylcholine is involved in the pathology of Parkinson's disease, too much acetylcholine actually inhibits the Basal Ganglia and can alleviate Parkinsonian symptoms. Therefore, the statement that too much acetylcholine will excite the CNS causing parkinsonian tremor is false.
