Intentional movement commands from the motor cortex are transferred via the axons of layer V pyramidal neurons, which make up the corticospinal tract, to the neurons of the spinal cord. From these, the α-motoneurons finally activate muscle fibres. Muscle contraction is monitored by Golgi tendon organs and muscle spindles and sensory information is fed back to the spinal circuits modulating the activity of the neurons in the spinal cord.
