Question

Quizplus · Accepted Answer

The correct sequence of events for the control of body movement is:
1) Stimulation of upper motor neurons in the cerebral cortex's motor area (3)
2) Activation of premotor areas in the cerebral cortex (6)
3) Descending tracts carry signals from the cerebral cortex to the spinal cord (1)
4) Stimulation of lower motor neurons in the spinal cord (5)
5) Skeletal muscle contraction (4)
Therefore, the correct sequence is 3, 6, 1, 5, 4. Thus, option A is the correct answer.
