Final answer:
The tibial nerve travels along the posterior compartment of the leg, near the soleal line of the tibia, and descends behind the medial malleolus.
Step-by-step explanation:
The tibial nerve travels along the posterior aspect of the fossa, specifically within the region known as the posterior compartment of the leg. The tibial nerve descends down the leg and passes posterior to the medial malleolus, following a pathway that is close to the posterior surface of the tibia. This area is delineated by several landmarks, including the soleal line of the tibia, which serves as an attachment point for muscles of the posterior leg, and extends diagonally across the proximal third of the posterior tibia.
