Review Exercise Figure 6.8

An illustration depicts the upper motor neuron in the primary motor cortex consisting of precentral gyrus sending an axon downward to lower motor neurons in the skeletal through the medullary pyramid and pyramidal decussation.
FIGURE 6.8 Lateral Corticospinal Tract Upper motor neuron in the primary motor cortex (precentral gyrus) sends an axon downward to cross over at the pyramidal decussation. The axon then continues downward in the contralateral spinal cord before synapsing on the lower motor neuron in the anterior horn.
