sensory nerve - spinal cord - motor nerve - effector work together to cause the reflex to lift the foot.
The spinal cord is a lengthy band of tissue that resembles a tube. It ties your brain and lower back together. Your spinal cord relays nerve messages back and forth from your brain to your body. You can experience feelings and move your body thanks to these nerve transmissions.
Nerve function is lost beneath the site of damage. A spinal cord damage higher up can paralyze the majority of the body and all limbs (called tetraplegia or quadriplegia). Legs and lower body paralysis may result from a lower spinal cord injury (called paraplegia).
