Neuroanatomy Week 3
1. the basal ganglia is a cluster of what located deep within the brain's forebrain
near the center lateral to the thalamus: cluster of neurons
2. the basal ganglia is also referred to as the: extrapyramidal motor system
3. the basal ganglia provides connections between the: cortex, thalamus, and subthalamic
nucleus
4. what are the four regions of the basal ganglia: striatum
subthalamic nucleus
globus pallidus
substantia nigra
5. role of the striatum: receives cortical inputs
6. role of the subthalamic nucleus: modulates movement through indirect pathway
inhibition to control movement
1/9
,7. globus pallidus role: main output of basal ganglia
8. substantia nigra role: synthesizes dopamine
sends output to thalamus and striatum
9. what is the striatum made up of: caudate
putamen
nucleus accumbens
10. what is the most cognitive part of the basal ganglia: caudate
11. the putamen is involved in preparing and executing: voluntary movements
12. the nucleus accumbent is what center: pleasure center involved in reward processing and
motivation
13. what is the entrance to the basal ganglia and receives dopamine from the
substantia nigra: striatum
14. where is dopamine synthesized: substantia nigra
2/9
, 15. the substantia nigra is found in what part of the brain but is also part of the
basal ganglia: midbrain
16. the substantia nigra is made up of: pars compacta
pars reticulata
17. what part of the substantia nigra supplies the striatum with dopamine: pars
compacta
