Pathway: The greater occipital nerve emerges from between the first and second cervical vertebrae. It ascends the cervical spine from just inferior to the obliquus capitis inferior muscle, where it is surrounded by a fat pad. It continues superiorly under cover of the...

Pathway: The lateral femoral cutaneous nerve emerges from spinal nerve L2 and L3 and is a pure sensory nerve. From its exit of the spine it passes between the two parts of the psoas muscle and emerges at its lateral aspect at the level of the iliacus muscle. The nerve...

Pathway: The saphenous nerve descends the thigh and into the leg to reach an area at the medial arch of the foot. Superiorly the saphenous nerve exits the femoral triangle to enter the adductor canal, just deep to the sartorius muscle. At the distal end of the...

Pathway: The femoral nerve arises from L2-L4 nerves from the lumbar plexus. The nerve forms within the matrix of the psoas major muscle and makes its way lateral and inferior to descend through the pelvis along a groove between the lateral margin of the psoas major...

Deep fibular nerve: After splitting at the fibular head from the superficial fibular nerve, the deep fibular nerve descends sharply around the fibular head to descend anterioinferiorly to pierce the septum between the lateral and anterior compartments of the leg. and...
