Motor Pathways

Item #2 of 10

How do the tracts composing the ventromedial pathway differ in general from the tracts of the dorsolateral pathway?

The ventromedial tracts are more discrete in the distribution of their final projection.;

The ventromedial tracts control contraction of the proximal muscles of the trunk and shoulders.;

Only the ventromedial tracts contain both pyramidal and extrapyramidal motor system elements.;

The ventromedial tracts project to both sides of the spinal cord.;

Both alternatives b and d are correct.;

CORRECT - Yes, unlike the dorsolateral pathways, the ventromedial pathways control the contraction of proximal muscles of the trunk and shoulder and they project to both sides of the spinal cord.
