Femoral Nerve Anatomy

The femoral nerve helps move your hips and knees anatomy. The femoral nerve innervates the muscles which allow for the flexion of the hip and extension of the knee.

Femoral Nerve Neupsy Key

Nerves are complex structures that branch out like a tree.

Femoral nerve anatomy. The femoral nerve helps in hip muscle movement and straightening of the legs and this forms the motor function. Femoral nerve is the major nerve supplying the anterior compartment of the thigh. This nerve has a triangular transverse cross section and passes through the pelvic region in the grove between.

Its principal function is to carry instructions to the muscles that straighten the leg such as the quadriceps found in the anterior thigh. Femoral nerve splits into two or three separate slips within the psoas muscle but unites to descend as a single bundle 2. The femoral nerve is the major nerve that serves the tissues of the thigh and leg including the muscles and skin.

The femoral nerve is one of the major nerves that innervates the legs. Fibres arise separately in lumbar plexus passes anterior to femoral nerve may terminate as saphenous nerve cutaneous branch. Femoral nerve dysfunction can occur when the nerve is compressed entrapped.

It may seem counter intuitive that the femoral nerve the nerve of the anterior thigh. The superficial branch of the femoral nerve first gives rise to the anterior. Piereces the sartorius and fasica lata medial to the knee and provides cutaneous innervation to the skin anteriorly over the patella.

The first motor branch innervates iliacus. It is the largest branch of the lumbar plexus and arises from the dorsal divisions of the ventral rami of the second third and fourth lumbar nerves l2 l3 and l4. The femoral nerve anatomy is conducive to selective stimulation with multicontact nerve cuff electrodes.

The femoral nerve supplies the muscles of the anterior thigh. While the much larger sciatic nerve also passes through the thigh on its way to the lower leg and foot only the femoral nerve innervates the tissues of the thigh. It provides sensory innervation to the skin of the anterior thigh.

The femoral nerve handles several important functions. We may also use selective stimulation of the compound femoral nerve to control distal muscles and functions such as leg extension at the knee joint.
