What does the femoral nerve innervate?

The motor branches of the femoral nerve are the nerve to pectineus, nerve to sartorius and muscular branches to the quadriceps femoris. They innervate the flexors of the hip (pectineus, iliacus, sartorius) and the extensors of the knee (quadriceps femoris).

Does the femoral nerve have cutaneous supply?

The anterior (superficial) branch of the femoral nerve first gives rise to the intermediate and medial cutaneous nerve of the thigh. They supply the skin on the anteromedial thigh. The posterior division gives only one cutaneous branch, the saphenous nerve which supplies the skin on the medial side of the foot and leg.

What does lateral femoral cutaneous nerve innervate?

The lateral femoral cutaneous nerve (also lateral cutaneous nerve of thigh, latin: nervus cutaneus femoris lateralis) is a long cutaneous nerve of the lumbar plexus. The lateral femoral cutaneous nerve innervates the skin of the lateral region of the thigh till the knee joint.

What does the posterior cutaneous nerve innervate?

The posterior cutaneous nerve of the thigh, also known as the posterior femoral cutaneous nerve, is a sensory nerve derived from the sacral plexus. It supplies the skin of the posterior thigh, buttock, posterior aspect of the scrotum or labia and a variable area of the posterior calf.

Where is the femoral cutaneous nerve?

The lateral femoral cutaneous nerve, also known as the lateral cutaneous nerve of the thigh, is a sensory branch of the lumbar plexus arising from the posterior divisions of the anterior rami of L2 and L3 spinal nerves.

What does the posterior femoral nerve innervate?

Via its numerous collateral branches, the posterior femoral cutaneous nerve innervates a very extensive territory including the posterior surface of the thigh, the infragluteal fold, the skin over the ischial tuberosity, but also the lateral anal region, scrotum or labium majus via its perineal branch.

What does posterior femoral cutaneous nerve do?

The posterior cutaneous nerve of the thigh (also called the posterior femoral cutaneous nerve) is a sensory nerve in the thigh. It supplies the skin of the posterior surface of the thigh, leg, buttock, and also the perineum.

Is the obturator nerve part of the femoral nerve?

This is the femoral nerve, this is the obturator nerve. The white structure between them is the psoas major tendon. Both these nerves arise from the lumbar plexus, which lies up here within the thickness of the psoas major muscle. The femoral nerve emerges lateral to psoas major, the obturator nerve medial to it.
