The basal ganglia's role in movement is to regulate desired movements and inhibit undesired movements.
True
False

Voluntary movement
Postural movement
Rhythmic movement
Muscle tone (force)
Match the type of basal ganglia motor loop pathway with its correct function.
Indirect pathway
Prevent undesired movements
Direct pathway
Allow desired movements
Basal ganglia
Prevent undesired and allow desired movements
What neurotransmitter is considered to be 'the fuel' of the basal ganglia?
Serotonin
Acetylcholine
Adrenaline
Dopamine
Dopaminergic producing neurons are found in the pars reticulata of the substantia nigra
True
False
The neurotransmitter dopamine enhances the indirect (brake) pathway of the basal ganglia and inhibits the direct (accelerator) pathway.
True
False
Which image below, either left or right diagram, reflects the action of the indirect pathway of the basal ganglia?
Left diagram
Right diagram
Parkinson's disease is a hyper-kinetic disease where the direct pathway is overactive, whereas Huntington's disease is a hypo-kinetic disease where the indirect pathway is overactive.
True
False
