Branches of the femoral nerve that supply the skin of the anterior thigh

The anterior cutaneous branches of the femoral nerve are branches of the femoral nerve that supply the skin of the anterior thigh. These branches are responsible for the sensory innervation of the skin in this region.

Anatomy

The anterior cutaneous branches arise from the femoral nerve, which is one of the major nerves of the lower limb. The femoral nerve originates from the lumbar plexus, specifically from the nerve roots of L2, L3, and L4.

Branches

The anterior cutaneous branches are divided into two main groups:

• The intermediate cutaneous nerve of the thigh
• The medial cutaneous nerve of the thigh

Intermediate Cutaneous Nerve of the Thigh

The intermediate cutaneous nerve of the thigh pierces the fascia lata and supplies the skin on the front of the thigh down to the knee.

Medial Cutaneous Nerve of the Thigh

The medial cutaneous nerve of the thigh also pierces the fascia lata and supplies the skin on the medial side of the thigh.

Function

The primary function of the anterior cutaneous branches of the femoral nerve is to provide sensory innervation to the skin of the anterior and medial aspects of the thigh. This includes the perception of touch, pain, and temperature.

Clinical Significance

Damage to the anterior cutaneous branches of the femoral nerve can result in loss of sensation or numbness in the skin of the anterior thigh. This can occur due to trauma, surgical procedures, or conditions such as diabetes mellitus.
