What are the spinal roots for the femoral nerve?
L2-L4 formed in the lumbar plexus
What are the muscles of the medial thigh compartment referred to as?
Why are the medial thigh muscles named the adductor gourp?
they act to adduct the thigh at the hip joint
What are the muscles of the medial thigh compartment?

obturator nerve (L2-L4)
What nerve supplies the hamstring part of the adductor magnus?
What 3 nerves give sensory innervation for the thigh?
anterior and lateral cutaneous nerves of the thigh
cutaneous branch fo the obturtor nerve
What does the anterior cutaneous nerve of the thigh come from?
femoral nerve (L2-L4)
What is the lateral cutaneous nerve of hte thigh a branch of?
lumbosacral plexus (L2-3)
