Item #3 of 10

The muscle contractions resulting in fine and discrete movements of the fingers are controlled uniquely by the _________________.

ventrolateral and ventral anterior nuclei of the thalamus;

ventromedial pathways;

corticospinal tract;

tectospinal tract;

none of the alternatives is correct because there is no one unique tract controlling discrete contractions of the muscles underlying discrete finger movements.;

CORRECT - Yes, the corticospinal or pyramidal tract uniquely controls the fine and discrete movements of the fingers.
