Study Notes

Femoral Nerve Branches

The femoral nerve has three types of branches:
- Muscular
- Cutaneous
- Articular
Muscular Branches:
- Supply the anterior thigh muscles (quadriceps femoris, sartorius, and pectineus)
- These branches supply the muscles and extend the knee joint
Cutaneous Branches:
- Supply sensory information to the medial and intermediate parts of the thigh skin
Articular Branches:
- The nerve branches deliver sensory information to the hip and knee joints

Femoral Nerve Course

The femoral nerve emerges from the lumbar plexus (L2-L4) and travels to the femoral triangle
The nerve branches run along the femoral artery to the knee, reaching the knee joint
It leaves the posterior wall of the femoral triangle close to the femoral artery, before supplying the front and medial thigh skin.
The sensory information from the muscle and the skin of the thigh and leg is conducted to the central nervous system.

Effect of Injury

Damage to the nerve results in motor and sensory deficits
Motor effects: paralysis of the knee extensor muscles
Sensory effects: loss of feeling in the front and medial thigh region and the skin of the leg and foot
