The set of coordinated commands that controls 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 controls programmed muscle activity mediated by extrapyramidal pathways is called the "motor program." The extrapyramidal tract refers to the group of nerve fibers that run from the brain to the spinal cord and are involved in the regulation of motor activity, but it does not specifically refer to the set of coordinated commands. The motor tract and pyramidal tract both specifically refer to the group of nerve fibers that run from the brain to the spinal cord and are involved in voluntary motor control, but again, they do not specifically refer to the set of coordinated commands.
