Question

what neurotransmitter is not secreted in sufficient quantity by neurons in the basal nuclei, leading to the development of parkinsons disease? multiple choice norepinephrine dopamine acetylcholine gaba

Explanation:

Parkinson's disease is caused by the degeneration of dopaminergic neurons in the basal nuclei (specifically the substantia nigra), leading to insufficient dopamine secretion. Norepinephrine is involved in the sympathetic nervous system, acetylcholine in muscle function and other roles, and GABA is an inhibitory neurotransmitter; none of these are the primary deficit in Parkinson's.

Answer:

B. Dopamine
