Open in App
Solution
The correct option is D Dopamine
Parkinson's disease (Paralysis agitans):
(i) develops due to deficiency of neurotransmitter, dopamine.
(ii) produces muscles tremors, the so-called shaking palsy.
(iii) is due to the lack of control and coordination of movements resulting in expression less face and stooping posture which gradually produces physical disability.
Norepinephrine is secreted in response to stress of any kind and during emergency situations and are called emergency hormones or hormones of Fight or Flight.
Acetylcholine helps with the contraction of cardiac, skeletal, and smooth muscles.
GABA is a chemical messenger that is widely distributed in the brainand helps reduce the activity of the neurons to which it binds.
