Lecture 1 lower limb overview Flashcards
what is the only way for a muscle to act on a joint?
need to cross the joint
primary bone of thigh?
femur
anterior muscles of the thigh function?
flex hip and knee
flexion of knee joint motion direction?
backwards at kneed joint
movements around ankle joint?
plantaflexion and dorsiflexion
iliotibial tract supported by what muscle?
gluteal maximus
tensor of fascia lata?
runs distaly and inserts on gerdis tibal, anterolateral
femoral nerve innervate what compartment?
anterior muscle group (quadricept)
obturator nerve innervate which group?
medial thigh muscles
sciatic nerve innervates which group of muscles?
posterior thigh and below knee
sciatic divides into what?
tibial and common fibular
external iliac called what after inguinal lgm?
femoral artery
deep femoral gives off which 2 brances?
medial and lateral femoral circumflex,
deep femoral also called what?
deep artery of thigh
peroneal artery supply what?
posterior aspect of the leg
peroneal artery divides into what in the tarsal tunnel?
medial and lateral plantar arteries
peroneal artery divides into what in the tarsal tunnel?
medial and lateral plantar arteries
great saphenous vein supplies?
medial part of foot leg and thigh
small saphenous vein drain into what?
popliteal vein in the popliteal fossa
lynph with small saphenous?
in popliteal fossa nodes
pymph with great saphenous vein drain where?
superficial inguinal nodes
whats in the ligament of head of femur?
branch of obturator arte.
acetabulum labrum function
helps create sng fit for the head of femus
articular capsule
rubury capsure around head of femur,
three lgmts that support head of femur in the acetabulum?
???
iliofemulral lgment
??
pubofemural lgmt?
helps create abduction of hip joint
zona orbicularis?
creates pull into acetabulum,
crusciate anastomosis?
collateral arterial supply for hip jint (head, neck or femur)
retinacular fibers?
travel along neck of femur runs with fibers, fraction there can cause necrosis of head of femurs.
muscles of gluteal region?
flexors of hip, iliopsoas, iliacus, pectineus, rectus femoris
gluteus max function
raising from a sitting position
trendelnburg sign
lose innervation superior gluteal nerve, wwhen lift leg, the other side is stabilized by other side, glut medius and minimus. classic dipping of hip
short lateral rotators of hip?
??
piriformis function
most imortant
piriformis syndrome?
neurovascular disorder, compression of sciatic nerve by piriformis. leading to pain along root of sciatic nerve, feels like disk problem.
intramuscular injection safest location in gluteus?
superolateral quadrant to avoid nerve????
meralgia peristhetica syndrome nerve involved?
lateral femoral cutaneus nerve
compartment syndrome?
compression from fraction or inflamation, fluid or blood accumulation in the compartment, the compression in the area can compress nerves and vessels, solution?? fasciotomy (cut fascia to release pressure in compartments)
