Injury to which peripheral nerve can cause the following symptoms: quadricep wasting, loss of knee jerk reflex, and numbness in the L2-4 dermatome?

The femoral nerve innervates the quadricep muscle group, the sartorius, and the iliacus. Like most peripheral nerves, it is a mixed nerve, so it carries sensory and motor nerve impulses. Femoral nerve damage can also cause partial numbness at the skin overlying the muscles that it innervates.
