In Parkinsonism the tremors, muscular rigidity and reduced control over voluntary movements appears to be a function of
A) damage to glia cells.
B) degeneration of neurons that use dopamine as a neurotransmitter.
C) agonistic chemical action on the receptor sites of the cerebrum.
D) enzymatic deficiency that does not allow for the proper cleanup of waste products in the nervous system.
Dopamine
A neurotransmitter involved in a number of functions, including mood, sleep, learning, and the reward system, often linked to feelings of pleasure and satisfaction.
Parkinsonism
A syndrome characterized by tremor, bradykinesia, rigidity, and postural instability, often associated with Parkinson's disease but can be caused by other conditions as well.
Muscular Rigidity
An increased tone of muscle tissue leading to stiffness and resistance to movement.
- Define the influence of specific neurotransmitters on neural transmission and behavioral actions, considering the contribution of agonists and antagonists.

Final Answer :
B
Explanation :
Parkinsonism is caused by the degeneration of neurons that use dopamine as a neurotransmitter, specifically in the substantia nigra region of the brain. This leads to a dopamine deficiency and results in the characteristic symptoms of Parkinsonism.
