Answer

Foot-ankle dorsiflexion or triple flexion (eg, foot-ankle dorsiflexion, knee and hip flexion) after plantar stimulation reflects only an intact spinal cord and sensory and motor nerves. Extensor movements (eg, arm elevation above the level of the shoulders) are more sophisticated motor actions than the dorsiflexion or triple flexion and require some cortical function.
