Femoral nerve

The femoral nerve or nerve crural is a nerve sensitivo-engine of the lower extremity, coming from L2, L3, L4. It is about the largest terminal section of the plexus lombal (the other being the obturating nerve). Its driving functions are the inflection of the Cuisse on the trunk, the extension of the Genou and incidentally the adduction of the thigh. It innerve the former face of the thigh, and the face antéro-mediale of the lower extremity.

Anatomy

The femoral nerve is born from the lumbar Plexus and moves ahead and in bottom inside the basin. It passes under the arcade crurale in front of the Muscle psoas. It goes down vertically in the thigh, releasing the many collateral ones.

Innervation and branches

collateral Branches:

*rameaux

muscular for the muscles iliaque, large psoas and pectinate

*rameau vascular for the femoral Artery

*rameau cutaneous for the former area of the thigh

Terminal sections:

*nerf of the quadriceps for the muscle of the same name, and the articulations coxo-femoral and of the knee

*nerf muscular side for the muscle sartorius and the intermediate and side area cutaneous of the thigh

*nerf muscular médial for the pectinate muscles and long supply main as well as the cutaneous area antéro-médiale of the thigh

*nerf saphene for the femoral artery, the face médiale of the thigh, the knee and the Calf, the articulation of the knee and two terminal sections former for the back of the foot and posterior for the edge médial of the foot
