Brain motor cortex pathways. Artwork of a sectioned human brain, brainstem and spinal cord, showing neural pathways (black lines) from the motor cortex of the brain. These are extrapyramidal pathways, which control involuntary movements and help co-ordinate movements (muscles at lower right). For an image showing similar neural pathways, see C016/6532. The top image is a vertical (coronal) section through the brain, the others are horizontal sections through areas such as the brainstem and spinal cord.
