Reflex Arc
The pathway that the nerve impulse takes from your foot to your leg is called the sensory pathway. This pathway includes sensory neurons that carry signals from the foot to the spinal cord and then to the brain, where the sensation of pain is perceived and a motor response is initiated to move away from the tack.
A nerve impulse travels from your leg to your brain through sensory neurons. Once in the brain, the impulse is processed, and a response is generated. The response travels back to your leg through motor neurons to initiate movement or action.
The nerve that supplies sensation and movement to the leg is called the sciatic nerve. It is the largest nerve in the body and branches into smaller nerves that innervate different parts of the leg.
An inability to extend the leg would result from a loss of function of the common peroneal nerve, a branch of the sciatic nerve. This nerve provides motor function to the muscles that extend the leg and dorsiflex the foot. Injury or compression of the common peroneal nerve can lead to weakness or paralysis in these muscles, resulting in difficulty extending the leg.
The sole of the foot is primarily innervated by the tibial nerve, a branch of the sciatic nerve. The tibial nerve carries sensory information from the plantar surface of the foot and is responsible for controlling the muscles involved in foot movement.

sciatic nerve
The posterior side of the thigh, leg, and foot are served by the tibial nerve. The tibial nerve is a branch of the sciatic nerve.
syathaic
The sciatic nerve serves the posterior leg and foot. It can be such a problem that the patient cannot pick up their toes.
deep peroneal nerve from the common peroneal never
Yes, the main nerve that runs on the inside of the leg is the saphenous nerve. It is a branch of the femoral nerve and provides sensory innervation to the skin on the inner aspect of the leg and foot.
The tibial nerve is the major nerve that serves the posterior leg and foot. It branches off from the sciatic nerve and travels down the back of the leg, providing motor and sensory innervation to the muscles and skin of the posterior lower leg and foot.
Numbness or pain in the FOOT or in the calf of your leg
The process is called a knee jerk reflex. It is a simple reflex that occurs when the patellar tendon is tapped, resulting in the lower leg kicking forward involuntarily.
The common peroneal nerve, also known as the common fibular nerve, is primarily derived from the L4-S2 nerve roots. It branches from the sciatic nerve in the posterior thigh and innervates muscles in the lower leg and foot. Its role includes motor functions for dorsiflexion and eversion of the foot, as well as sensory functions in the skin of the lower leg and the dorsum of the foot.
