34
the hamstring part of adductor magnus is innervated by
tibial part of sciatic
35
Patellar Plexus
cutaneous inervation around the patella - intermediate femoral cutaneous - medial femoral cutaneous - lateral femoral cutaneous - saphenous (infrapatellar)
36
subsartorial plexus
medial thigh cutaneous innervation -deep to sartorious and distal part of add long composed of: Anterior branch of obtorator -medial femoral cutaenous -saphenous
37
what nerves are apart of both patellar plexus and subsartorial
- saphenous nerve | - medial femoral cutaneous
38
most commonly strained adductor

44
External iliac (inferior epigastric) annastamoses with
obturator artery
45
gluteal arteries can anastamose with
profunda femoris branches
46
medial circumflex femoral and inferior gluteal can anastamose with
