FEMORAL NERVE

Q. 1

 A

Femoral nerve

 B

Sural nerve

 C

Tibial nerve

 D

Q. 1

The skin overlying the region where a venous “cut-down” is made to access the Great saphenous vein is supplied by?

 A

Femoral nerve

 B

Sural nerve

 C

Tibial nerve

 D

Superficial peroneal nerve

Ans. A

Explanation:

The skin overlying the region where a cut down is made to grant access to the great saphenous vein is supplied by the saphenous nerve. The saphenous nerve is a branch of the femoral nerve.


Q. 2

Saphenous nerve is a branch of:  

 A

Tibial nerve

 B

Sciatic nerve

 C

Common peroneal nerve

 D

Femoral nerve

Q. 2

Saphenous nerve is a branch of:  

 A

Tibial nerve

 B

Sciatic nerve

 C

Common peroneal nerve

 D

Femoral nerve

Ans. D

Explanation:

Branches of femoral nerve

  • Anterior division: In the thigh the anterior division of the femoral nerve gives off anterior cutaneous and muscular branches.

Anterior cutaneous branches: The anterior cutaneous branches comprise the following nerves:

  • Intermediate femoral cutaneous nerve and
  • Medial femoral cutaneous nerve

Muscular branches (rami musculares):

  • The nerve to the Pectineus arises immediately below the inguinal ligament.
  • The nerve to the Sartorius arises in common with the intermediate cutaneous.
  • Posterior division: The posterior division- muscular branches supply the four parts of the Quadriceps femoris.

– The branch to the Rectus femoris enters the upper part of the deep surface of the muscle, and supplies a filament to the hip-joint.

– The branch to the Vastus lateralis, of large size, accompanies the descending branch of the lateral femoral circumflex artery.

The branch to the Vastus medialis descends lateral to the femoral vessels in company with the saphenous nerve.

– The branches to the Vastus intermedius.

– The articular branch to the hip-joint is derived from the nerve to the Rectus femoris.

  • The articular branches to the knee-joint are three in number.

One, a long slender filament, is derived from the nerve to the Vastus lateralis.

– Another, derived from the nerve to the Vastus medialis

– The third branch is derived from the nerve to the Vastus intermedius.


Q. 3

Femoral nerve supplies all except ‑

 A

Pectineus

 B

Sartorius

 C

Vastus medialis

 D

Obturator externus

Q. 3

Femoral nerve supplies all except ‑

 A

Pectineus

 B

Sartorius

 C

Vastus medialis

 D

Obturator externus

Ans. D

Explanation:

Branches of femoral nerve are :‑

  1. From the main trunk :- Nerve supply to iliacus, nerve supply to pectineus and a few vascular branches.
  2. From anterior division :- Intermediate femoral cutaneous nerve (intermediate cutaneous nerve of thigh), medial femoral cutaneous nerve (medial cutaneous nerve of thigh) and muscular branch to sartorius.
  3. From posteior division :- Saphenous nerve, nerve supply to quadriceps femoris (rectus femoris, vastus medialis, vastus lateralis, vastus intermedius).
  4. Articular supply :- Hip joint is supplied by nerve to rectus femoris; knee joint is supplied by nerve to three vasti.
