The iliacus muscle gets nerve supply from the femoral nerve at lumbar levels two, three, and four. The psoas major is innervated by direct branches of the lumbar plexus, specifically from L1-L3.

The lateral femoral cutaneous nerve is a branch of the lumbar plexus, exiting the spinal cord between the L2 and L3 vertebrae. It emerges at the lateral edge of the psoas muscle group, below the ...

The femoral nerve is one of the largest nerves in the body. It begins in the pelvis and separates into several smaller branches. These nerve branches control the movements of various leg muscles.

and a muscle called Psoas major a main culprit. The muscle has intimate links to the 'femoral nerve' so that tension within the muscle and its surrounding tissues may contribute to further ...

And, since the psoas connects to the diaphragm via fascia—a nerve-filled tissue that supports muscles, bones, and organs—“it kind of connects breathing and walking,” says Lake. How ...

Background To define the sites where the lateral femoral ... fasciae latae muscle and the sartorius was used as an initial sonographic landmark. The time taken to identify the nerve was recorded.
