The set of coordinated commands that control programmed muscle activity mediated by extrapyramidal pathways is called the:
A)extrapyramidal tract.
B)motor program.
C)motor tract.
D)pyramidal tract.

Question

Quizplus · Accepted Answer

The set of coordinated commands that control programmed muscle activity is called a motor program. This program can be mediated by both pyramidal and extrapyramidal pathways, but the extrapyramidal pathways are specifically involved in the modulation of motor programs and their execution. Therefore, options A, C, and D are not accurate descriptions of the extrapyramidal pathways as a whole.
