Hip Flexors: i. Pectineus - Loss of adduction, flexion, and medial rotation of the hip ii. Iliacus - Loss of flexion and stabilization of the hip joint iii. Sartorius - (a)Loss of flexion, abduction, and lateral rotation of the hip& (b)Loss of knee flexion Knee Extensors Quadriceps femoris (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius) (a)Loss of knee extension & stabilization (b)Loss of hip flexion (rectus femoris) |

Femoral nerve lesion - sensory loss |
Anterior femoral cutaneous nerve - Loss of anteromedial thigh sensation Saphenous nerve - Loss of sensation to skin & fascia on anteromedial aspects of the knee, leg, & foot |
|
|
Femoral nerve lesion - motor disabilities |
a. Problems with standing, walking, and running b. Voluntary knee extension c. Voluntary hip flexion - [Note: small amount of hip flexion remains via tensor fasciae latae m.] d. Knee extension reflex/myotatic reflex (areflexia) -Lower motor neuron damage e. Neurogenic atrophy -Results in the feeling of the leg/knee giving out |

Femoral nerve lesion |
-Femoral n. (L2-L4) originates in the abdomen from LS plexus and descends posterolaterally to reach the inguinal lig. -Enters femoral triangle, lat. to the vessels, divides in to several branches to the ant. thigh mm., cutaneous brr. to anteromedial side of thigh -Gives rise to saphenous n. which supplies skin of anteromedial knee, leg, & foot |
