Dopamine is predominantly engaged in gross, unconsciously occurring motions of the skeletal muscles, which has an impact on motor function.
Dopamine is a neurotransmitter that predominantly influences motor control and is involved in large-scale, unintentional skeletal muscle contractions. Dopamine also contributes to emotional reactions. Parkinson's disease is characterized by a dopamine deficit and tremors or uncontrollable quivering motions in the sufferer. Acetylcholine contributes to the speedy transmission of nerve impulses by spilling into the synapse region. Norepinephrine affects arousal maintenance, dreaming, and mood modulation.
