Lower body anatomy (final) Flashcards
What is the main extensor muscle of the thigh and what is its nerve supply?
Gluteus maximus (inferior gluteal nerve)
What are the main abductors of the hip and what is their nerve supply?
Gluteus medius and minimus Superior gluteal nerve
What is the function and nerve supply to the anterior thigh?
Extension at the knee Femoral nerve
What is the function and nerve supply of the medial thigh?
Adduction of the lower limb Obturator nerve
What is the function and nerve supply of the posterior thigh?
Flexion at the knee Sciatic nerve (tibial)
What is the test for each of the ligaments of the knee?
ACL = Lachmans/anterior drawer PCL = posterior drawer Menisci = Lateral/medial steinmans Collaterals = varus/valgus stress
What is the function and nerve supply to the anterior leg?
Deep fibular nerve Dorsiflexion + inversion
Which is the anterior tibial muscle?
Bulge next to the tibia
What is the function and nerve supply to the lateral leg?
Superficial fibular nerve Eversion
What is the nerve supply and function of the posterior leg?
Tibial nerve (extension of sciatic) Plantarflexion (+ flexion of toes)
Which muscles are hip flexors?
Sartorius,
Iliopsoas (iliacus, psoas major)
Rectus femoris (quad)
Pectineus
What ligaments are associated with the hip joint?
Intracapsular: ligament of head of femur
Extracapsular: ischiofemoral, iliofemrral, pubofemoral
What is the blood supply to the femur and what are its branches?
Femoral artery Medial and lateral circumflex arteries (supply the head/neck) Profunda femoris (supply the
Draw the bones of the foot
What are the parts of the pelvic bone?
What muscles are in the laterla compartment of the leg?
Fibularis longus and brevis
Where does sartorius travel?
ASIS - medial knee
What nerve in damaged in Trendellenburgs gait?
Superior gluteal nerve (fail to abduct - gluteus medius + minimus)
What is the superficial and deep venous drainage of the lower limb?
Deep: follows vessels (anterior tibial, posterior tibial, fibular - popliteal, femoral, external iliac)
Supericial: small saphenous into popliteal vein, great saphenous into femoral vein)
What is contained within the femoral triangle and what forms the borders?
Lateral border: sartorius
Medial border: Adductor lungus
Superior border: inguinal ligament
Lat - med: NAVY
femoral nerve, femoral artery, femoral vein, femoral canal (lymphatics)
What is the blood supply to the lower limb?
Femoral artery
Popliteal artery
Tibiofibular trunk (branch for anterior tibial artery)
Divides into posterior tibial artery and fibular artery
Anterior tibial artery becomes dorsal pedis at ankle
What are the lymph nodes of the lower limb and what drains into each/where are they?
Superficial inguinal: penis, scrotum, perineum, bum (under inguinal ligament)
Superficial sub-inguinal: superficial lymph (by great saphenous vein)
Deep sub-inguinal: deep lymph (by femoral vein)
Popliteal: behind knee (continues to deep sub-inguinal nodes by femoral vein)
