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)
Nerves of the right lower extremity Posterior view. (medial calcaneal labeled at bottom left.) Diagram of the segmental distribution of the cutaneous nerves of the sole of the foot.
The tibial nerve is the larger terminal branch of the sciatic nerve with root values of L4, L5, S1, S2, and S3. It lies superficial (or posterior) to the popliteal vessels, extending from the superior angle to the inferior angle of the popliteal fossa, crossing the popliteal vessels from lateral to medial side.
The posterior tibial artery is used as a landmark for the tibial nerve as both structures enter the foot. [4] Local anaesthetic is injected either side of the artery distal to the flexor retinaculum of the foot, close to the calcaneus. [4]
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 ...
a lateral branch which passes anteriorly superficial to the second intermetatarsal space to give rise to the give rise to the lateral digital dorsal nerve of the second toe, and the medial digital dorsal nerve of the third toe. [1] It also supplies the integument of the medial side of the foot and ankle. [citation needed] [verification needed]
The deep fibular nerve from the common fibular nerve provides the sensory innervation of the skin between the first and second toes and the motor innervation of the muscles of the anterior compartment of the leg and dorsal foot. Damage to the deep fibular nerve can result in foot drop. [7]
