1

What are the motor and sensory functions of the femoral nerve?

Motor: muscles of the anterior compartment of the thigh, as well as the iliacus and pectineus. (Hip flexors and quads).

Sensory: skin on anterior thigh and medial leg (from the saphenous branch).

Motor: muscles of the medial compartment of the thigh – obturator externus, pectineus, etc.

Sensory: skin of anterior scrotum or mons pubis and labium majus – skin of upper anterior thigh and medial thigh.

(Genital and femoral sensation come from two branches, the genital branch and the femoral branch)

4

What are the motor and sensory functions of the ilioinguinal nerve?

Motor: internal oblique and transversus abdominis.

Sensory: skin of the upper medial thigh, and either the skin over the root of the penis and anterior scrotum – or the mons pubis and labium majus.

5

What is the sensory function of the lateral cutaneous nerve of the thigh (lateral femoral cutaneous nerve)?

Sensory: skin on the anterior and lateral thigh, down to the knee.

6

What are the motor and sensory functions of the iliohypogastric nerve?
