Cutaneous innervation of the lower limbs is the nerve supply to areas of the skin of the lower limbs (including the feet) which are supplied by specific cutaneous nerves. Modern texts are in agreement about which areas of the skin are served by which nerves , but there are minor variations in some of the details.
The intermediate cutaneous nerve (middle cutaneous nerve) pierces the fascia lata (and generally the sartorius) about 7.5 cm below the inguinal ligament, and divides into two branches which descend in immediate proximity along the forepart of the thigh, to supply the skin as low as the front of the knee.
Usually, in this case, motor function of the lower leg will not be impaired. This is a key distinction between saphenous nerve neuropathy and lower back radiculopathy. Saphenous nerve neuropathy only demonstrates sensory alterations, while lumbar radiculopathy will affect the motor, sensory, and deep tendon reflexes of the lower leg. [6]
The posterior cutaneous nerve of the thigh provides sensory innervation to most of [2] the posterior surface of the thigh (upper leg), [2] [1] and the superior [1] part of the posterior surface of the leg (lower leg), [2] [1] as well as (the inferior part of) the gluteal region (via inferior cluneal nerves, derived from anterior rami of S1-S2 ...
The common fibular nerve is the smaller terminal branch of the sciatic nerve. The common fibular nerve has root values of L4, L5, S1, and S2. It arises from the superior angle of the popliteal fossa and extends to the lateral angle of the popliteal fossa, along the medial border of the biceps femoris.

In human anatomy, the sacral plexus is a nerve plexus which provides motor and sensory nerves for the posterior thigh, most of the lower leg and foot, and part of the pelvis. It is part of the lumbosacral plexus and emerges from the lumbar vertebrae and sacral vertebrae (L4-S4). [1]
The femoral nerve is a nerve in the thigh that supplies skin on the upper thigh and inner leg, and the muscles that extend the knee. It is the largest branch of the lumbar plexus . Structure
