Must Read:

The femoral nerve is one of the significant fringe nerves of the lower appendage. The femoral nerve is basic for exercises of day by day life including strolling and climbing stairs. Without it, the lower appendage turns out to be extremely debilitated. In this article we will talk about its course, its engine and tactile innervation and in addition clinical pertinence.

In this article, we will take a gander at the life structures of the femoral nerve – its anatomical course, engine, and tactile capacities, and any clinical importance.

The nerve slides from the lumbar plexus in the belly, going down through the filaments of psoas major. The nerve exits psoas major at the lower some portion of its sidelong outskirt, going behind the iliac belt to around the mid-purpose of the inguinal tendon.

Iliacus – acts with psoas major and psoas minor (shaping iliopsoas) to flex the thigh at the hip joint and balance out the hip joint.

Sartorius – flexes, snatches and horizontally turns the thigh at the hip joint. Flexes the leg at the knee joint.

Knee Extensors

Quadriceps femoris (rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius) – broadens the leg at the knee joint. Rectus femoris likewise steadies the hip joint and helps iliopsoas in flexing the thigh.
