The primary motor cortex is the beginning of descending pathways which innervate skeletal muscle cells. Based on the examples in the figure, how many total neurons are required to reach the target skeletal muscle cells from the primary motor cortex? Circle areas of decussation. This means that skeletal muscle contractions on the right side are controlled by the side of the brain, and vice versa. Optional: Do you know someone who has experienced brain damage on one side of the brain that has affected motor control on the other side of the body? How many motor neurons does it take to reach skeletal muscle cells from the spinal cord?
