Lumboinguinal nerve (green) and Ilioinguinal nerve (purple). In modern texts, these two regions are often considered to be innervated by the genitofemoral nerve. Medial cluneal nerves (pink) - labeled as "post. division of sacral" Inferior cluneal nerves (pink region, not designated with its own section)
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 superficial fibular nerve (also known as superficial peroneal nerve) is a mixed (motor and sensory) nerve that provides motor innervation to the fibularis longus and fibularis brevis muscles, and sensory innervation to skin over the antero-lateral aspect of the leg along with the greater part of the dorsum of the foot (with the exception of the first web space, which is innervated by the ...
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.
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.
The sural nerve (L4-S1) is a cutaneous sensory nerve of the posterolateral calf with cutaneous innervation to the distal one-third of the lower leg. [1] Formation of the sural nerve is the result of either anastomosis of the medial sural cutaneous nerve and the sural communicating nerve, or it may be found as a continuation of the lateral sural cutaneous nerve [2] traveling parallel to the ...
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 medial dorsal cutaneous nerve (internal dorsal cutaneous branch) is the more medial one of the two terminal branches of the superficial fibular nerve (the other being the intermediate dorsal cutaneous nerve). Through its branches, it provides innervation to parts of the dorsal aspects of the first, second, and third toes.
