EXTREMITAS INFERIOR Sufitni Mega Sari Sitorus Tulang-Tulang Yang Membentuk Ekstremitas Inferior Os Coxae Os Femur Os Patella Os Tibia – Fibula Os Tarsalia Os Metatarsal Os Phalanges OS Coxae Pada bagian anterolateral terdapat mangkuk sendi = fossa acetabuli, bersendi dgn caput femoris Pada pinggir fosssa acetabuli terdapat penebalan yang dilapisi oleh tulang rawan Facies Lunata FEMUR Pada bgn atas terdapat caput femoris Dibagian atas caput ini terdapat fovea capitis yg merupakan tempat melekat ligamentum teres femoris Bagian – Bagian Femur , antara lain : • Trochanter major , minor • Fossa trochanterica : tempat insersi otot bokong • Linea aspera - labium interna : tpt origo otot –otot adductor - labium eksterna ; origo m.biceps femoris caput brevis Tulang-Tulang Yang MembentukPergelangan Kaki ( ossa tarsalia) - os calcaneus os tallus os naviculare pedis os cuneiforme I, II, III os cuboideum Perdarahan Pada Ekstremitas Inferior • A. Femoralis • A. Poplitea • A. Tibialis Anterior • A. Tibialis Posterior • A. Peronea • V. Femoralis • V. Saphena magna • V. Saphena parva Posterior Thigh • Gluts (gluteal nn.) • Maximus—extensor of thigh • Medius--pelvic tilt • Lateral rotators (spinal nn.) • Piriformis syndrome • Hamstrings (sciatic n.) Frolich, Human Anatomy, Lower • Biceps femoris • Semimembranous • Semitendinous Anterior thigh (femoral n • Sartorius (Tailor’s muscle) • Quads (four) • Rectus femoris (crosses hip) • 3 vastus mm. (vast--big) Frolich, Human Anatomy, Lower Medial compartment (obturator n.) • Adductor muscles • Gracilis • Adductor • Magnus • Longus • brevis Frolich, Human Anatomy, Lower Anterior Leg (deep fibular n.) • Fibularis (peroneus) longus • Extensor digitorum longus • Extensor hallicus longus • Tibialis anteriorus Frolich, Human Anatomy, Lower Lateral Leg (superficial fibular n.) • Fibularis brevis/longus Frolich, Human Anatomy, Lower Posterior Leg (tibial n.) • Gastrocs and soleus • Flexor digitorum longus • Flexor hallucus longus Frolich, Human Anatomy, Lower Intrinsics of foot Frolich, Human Anatomy, Lower Blood supply to lower limb Internal Iliac Cranial + Caudal Gluteals= gluteals Internal Pudendal = perineum, external genitalia Obturator = adductor muscles External Iliac Femoral = lower limb • Deep femoral = adductors, hamstrings, quadriceps Popliteal (continuation of femoral) • Geniculars = knee • Anterior Tibial = ant. leg muscles, further branches to feet • Posterior Tibial = flexor muscles, plantar Frolich, Human arch,Lower branches to toes Anatomy, • Sacral plexus (sciatic nerve) With leg out to side like quadruped, lumbar-anterior, sacral-posterior makes sense • Lumbar plexus (femoral nerve)
