Anatomy · Lower limb: femoral nerve

Sample item

A pelvic mass compresses the femoral nerve. Which movement is most weakened?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Knee extension

The femoral nerve supplies quadriceps femoris, the major extensor of the knee, and provides sensation to the anterior thigh and medial leg via the saphenous nerve.

Option by option

  • A. Ankle plantarflexion

    Plantarflexion is mainly tibial nerve function.

  • B. Hip adduction

    Hip adductors are supplied mainly by the obturator nerve.

  • C. Toe flexion

    Toe flexion is supplied by tibial-nerve branches.

  • D. Knee extension (correct)

    Correct. Quadriceps weakness makes knee extension difficult.
