Knee flexion is mediated by which nerve roots via the Hamstrings?

Explanation:
Knee flexion with the hamstrings is carried out by muscles that are innervated by the sciatic nerve, specifically its tibial division for most of the hamstrings. The nerve root pattern most relevant to knee flexion lies around L5 through S2, with L4 being more associated with knee extension via the quadriceps. Therefore, the primary roots contributing to hamstring-mediated knee flexion are L5, S1, and S2, which is why this set best explains the innervation of knee flexors.
