fem·o·ral nerve

[TA]
arises as a branch of the lumbar plexus, conveying fibers from the second, third, and fourth lumbar nerves through the substance of the psoas muscle and enters the thigh via the retroinguinal muscular space posterior to the inguinal ligament, lateral to the femoral vessels; it arborizes within the femoral triangle into muscle branches to the sartorius, pectineus, and quadriceps muscles and anterior femoral cutaneous branches to the skin of the anterior and medial region of the thigh; its terminal branch is the saphenous nerve by which it supplies the skin of the medial leg and foot.
Synonym(s): nervus femoralis [TA], anterior crural nerve

fem·o·ral nerve

(fem'ŏr-ăl nĕrv) [TA]
Arises from the second, third, and fourth lumbar nerves in the substance of the psoas muscle and enters the thigh through the muscular lacuna beneath the inguinal ligament, lateral to the femoral vessels; it arborizes within the femoral triangle into muscle branches to the sartorius, pectineus, and quadriceps muscles and anterior femoral cutaneous nerves to the skin of the anterior and medial region of the thigh; its terminal branch is the saphenous nerve by which it supplies the skin of the medial leg and foot.
Synonym(s): nervus femoralis [TA] .

femoral nerve

One of the main nerves of the leg. It branches widely to run into the group of large muscles on the front of the thigh and to carry back sensation from the skin on the front and inner aspects.

(2009) studied the origin and distribution of the femoral nerve in fetuses of crossbreed zebu cattle and found that the right and left femoral nerves originated from the ventral branches of L4, L5 and L6 in 14 animals (46.7%), from L4 and L5 in 13 cases (43.3%) and L5 and L6 in three cases (10%), similar to that observed in this study in rabbits and to the results obtained by Silva et al.
