Motor Pathways

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.;

INCORRECT - The tectospinal tract works to improve the spatial accuracy of movements.
