Involuntary Movements
Perhaps the simplest and most fundamental movements are reflexes. These are relatively fixed, automatic muscle responses to particular stimuli, such as the slight extension of the leg when a physician taps the knee with a small rubber hammer.

More Complex Movements
Networks of spinal neurons also participate in controlling the alternating action of the legs during normal walking, maintaining posture, and, to a large degree, in all movements.
