Anterior Compartment of the Thigh Flashcards
fascia lata
where
what is in it
anterior thigh fascia
thick
where great saphenous vein is
medial malleolus and grat saphenous vein relationship
great sap vin is superficial to anterior of medial malleous
what is saphenous opening
hole in fascia lata
-where great sap vein ends in femoral vein
femoral vein
end of great sap vein proximal
starts distally in saphenous opening
illotibial tract
what is it
where is it
whats in it
thickening of fascia lata
lateral aspect of thigh
stretches from iliac crest to lateral condyle of tibia
tensor fasciae latae
tensor fasciae late where is it/attachments
anterior iliac spine
iliotibial tract
tensor fasciae latae innervation
superior gluteal nerve
l4-s1
tensor fasciae latae actions
tense fascia lata
abduct, flex, internally rotate femur at hip
what innervates all muscles on anterior thigh
femoral nerve l2-3
what four muscles make up quadriceps femoris
what makes them different
-other muscle in there
rectus femoirs-middle
vastus lateralis-lateral
-sartorius also in here and more lateral/thinner and starts much higher
vastus medialis-medial
vastus intermedius-deep????
sartorius attachments and innervation
anterior iliac spine
tibial tuberosity together with gracilis and semitendinosus muscles
femoral l2-4
sartorius actions
fle, abduct, and extremely rotate femur at hip
flex and internally rotate leg at knee
Rectus Femurs attachments/innervation
anterior ifnerior iliac spine and roof of acetabulum
tibial tuberosity via paterallar ligament
femoral nerve l2-4
Rectus Femurs action
flex femur at hip joint
extend knee at knee joint
vastus lateralis attachemnts/innervation
lateral lip of line aspera and lateral surface of greater trochanter of femur
tibial tuberosty via patellar ligament and
both sides of tuberosity on the medial and lateral condyles of tibia via medial and longitudinal patellar retinacula
femoral l2-4
vastus lateralis actions
extend leg at knee joint
vastus medals attachments/innervation
medial lip of line aspera and interechanteric line
tibial tubersoty via patellar liagemnts and onto both sides of tuberosity on medial and lateral condyles of tibia via medial and longitudinal patellar retinacula
femoral nerve l2-4
vastus medialus actions
extend leg at knee joint
vastus intermdius attachments/innervation
anterior side of femoral shaft
tibial tuberosity via patellar ligament
femoral nerve l2-4
vastus intermedius actions
extend leg at knee joint
what attaches to patellar tendon
where does it go
all 4 parts of quad
passes to the patella
patellar ligament comes from
attaches to
patellar tendon
continuation of quad tendon past patella to attachment on tibial tuberoisty
femoral triangle
roof
superior border
lateral border
medial border
floor-laterally
and medially
roof-=fascia late
superior-inguinal ligament
lateral-sartorius
medial-adductor longus
lateral floor-iliopsoas
medial floor-pectineus
ilipsoas attachments
psoas
- lateral surfaces of t12 to l4 introvert disks and spinous processes of l1 to l5 vert
- lesser trochanter of femur
ilicus
- iliac fossa
- lesser trochanter of femur
iliopsoas innervation
psoas-lumbar plexus l2 to l4
ilicus-femoral nerve l2-4
iliopsoas actions
flex and externally rotate femur at hip joint
unilaterally-femur fixed-acts to bend trunk laterally to same side
bilaterally-rause trunk from supine position
pectineus attachments
pectin pubis
pectineal line and proximal line aspera
pectineus innervation
femoral nerve and obtrutar nerve
l2 and 3
pectineus actions
adduct, externally rotate, and slightly flex femur at hip joint
stabilize pelvis in coronal and sagittal planes
contents offemoral triangle from lateral to medial
femoral nerve
femoral artery
femoral vein
what does femoral nerve do
provide motor and sensory innervation to structures in anterior compartment
what is femoral sheath
- how divided
- what in compartments
extension of transversalis fascia from abdomen
-lateral-femoral artery
intermediate-femoral vein
medial-femoral canal-fat and lyphatics
branches of femoral artery +a little about them
profonda (deep) femoral artery-chief artery of thigh
medial femoral circumflex-from femoral or profound femoral
-passes medially between pecans and iliopsoas muscles
lateral femoral circumflex-braces off deep femoral artery
-gives off ascending and descending brancehes
what is under sartorius
what occurs here
whats in here
subsartorial (adductor canal)
atherosclerotic lesions
-decreased blood flow to legs
saphenous nerve
femoral artery and vein
where does saphenous nerve come from
femoral nerve
where do femoral artery and vein go to
disppear in adductor hiatus (defecincy of tendon of adductor magnus
enter popliteal fossa
become popliteal artery and vein
what is adductor hiatus
deficiency of adductor magnus tendon
femoral artery and vein disappear through here
makes small canal type thing for femoral artery and vein to go through before hit popilital fossa
