describe the nerve schematic

cranial / medial= femoral → saphenous (medial caudal)

obturator = middle, goes through obturator foramen

lateral / caudal = sciatic nerve → tibial (caudal) and common fibular (cranial)

• tibial → lateral plantar nn.

• common fibular → deep and superficial peroneal nn.
