THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The sural nerve provides cutaneous innervation to the skin of the posterior to posterolateral leg. This nerve is part of the sciatic nerve sensorium. It only provides autonomic and sensory nerve fibers to the skin of the posterolateral leg and ankle.

Detailed explanation-2: -aka musculocutaneous nerve; a nerve that extends down the leg, just under the skin, supplying impulses to the muscles and the skin of the leg, as well as to the skin and toes on the top of the foot. Extends up from the toes and foot, just under the skin.

Detailed explanation-3: -The sciatic nerve, which provides motor innervation to the muscles of the posterior thigh and sensory innervation to the lateral side of the lower leg and lateral side and sole of the foot, ends just above the posterior knee in the popliteal fossa and bifurcates into the common fibular and tibial nerves.

Detailed explanation-4: -The sural nerve does not innervate any muscle groups as it only provides sensory innervation of the skin. It does, however, travel subcutaneously between the two heads of the gastrocnemius.
