Tibial nerve
The tibial nerve is a branch of the sciatic nerve. The tibial nerve passes through the popliteal fossa to pass below the arch of soleus.
Tibial nerve
Origin: Flexor digitorum longus, flexor hallucis longus
Anterior: semimembranosus, semitendinosus, long head of biceps femoris
Medial: abductor hallucis, flexor digitorum brevis, flexor hallucis brevis, first lumbrical
Lateral: quadratus plantae, flexor digiti minimi, adductor hallucis, the interossei, three lumbricals and abductor digiti minimi
nervus tibialis
Structure[edit]
Popliteal fossa[edit]
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. It gives off branches as shown below:[1]
