: Meets with lateral tarsal artery to form an arterial loop o Gives rise to the 2 nd , 3 rd , and 4 th dorsal metatarsal arteries - Arteries of Sole of Foot: Prolific blood supply from posterior tibial artery Medial Plantar Artery : Smaller terminal branch of posterior tibial artery o Supplies mainly muscles of great toe Lateral Plantar Artery : Much larger than medial o Forms deep plantar arch which is completed with union with deep plantar artery o Deep plantar arch gives rise to 4 plantar metatarsal arteries & 3 perforating branches -Venous Drainage of Foot : Deep veins accompany arteries while superficial do not Perforating Veins : Superficial to deep blood flow o Essential for operation of the musculovenous pump (proximal to ankle joint) Deep Veins : Augmented by ambulation (compression and acitiity of intrinsic foot muscles) increasing flow from deep plantar arch to posterior tibial vein Superficial Veins : o Medial Marginal Vein : Becomes the great saphenous vein o Lateral Marginal Vein : Becomes the small saphenous vein

QUIZ QUESTIONS -muscles that help with eversion of foot attach to what metatarsal? = 5 -accompany small saphenous vein and = sural -7 tarsals, 5 metatarsals, 14 phalanges -plantar aponeurosis protects flexors -plantar muscles function during stance phase helping with stability & longitudinal arch -vein that help superficial flow of blood in foot = - deep fibular vein serves what? = extensor hallucis, extensor digitorum, dorsal side of foot, skin of 1 st &2 nd metatarsals - abductor, bipennate = DAB Lower Limb Quiz 6 - Hip Joint : Socket type of synovial joint Thick parts of fibrous layer form the ligaments of the hip joint o Iliofemoral Ligament : Y-shaped ligament Body’s strongest ligament Prevents hyperextension of hip joint o Pubofemoral Ligament : Prevents overabduction of hip joint o Ischiofemoral Ligament : Weakest of the 3 hip ligaments Movements of Hip Joint : Flexion/extension, abduction/adduction, medial/lateral rotation & circumduction o Main muscles the provide movement of hip joint are the iliopsoas, adductor magnus/longus/brevis, pectineus, Gracilis, and gluteus muscles Retinacular Arteries : Main blood supply of hip joint (arise from medial circumflex artery) - Knee Joint : Hinge type of synovial joint Allows flexion & extension Knee Joint has 3 Articulations : o Two femorotibial articulartions (lateral/medial) o One femoropatellar articulation Fibula is not involved in the knee joint Quadriceps femoris is the most important muscle in stabilizing the knee joint Most common knee injury in contact sports is ligament sprains Joint Capsule Strengthened by 5 Ligaments : o 1.) Patellar Ligament o 2.) Fibular Collateral Ligament (FCL) o 3.) Tibial Collateral Ligament (TCL ): TCL is weaker than FCL and therefore is more often injured TCL & medial meniscus commonly torn during contact sports o 4.) Oblique Popliteal Ligament o 5.) Acruate Popliteal Ligament Cruciate Ligaments : Cross within joint capsule but outside the synovial cavity o
