what nerve branches from the femoral nerve to supply the anteromedial aspects of the knee, leg and medial foot
saphenous nerve
what forms the borders of the femoral triangle
what does it contain?
inguinal ligament
adductor longus
sartorius
NAVY femoral nerve femoral artery femoral vein deep inguinal lymph nodes
does the femoral sheath envelope the femoral nerve?
no
only the femoral artery and vein
what is the femoral artery a continuation of
external iliac > femoral artery
what nerve supplies the first web space of the foot?
deep fibular nerve
what does the sural nerve supply
skin of posteriolateral aspect of leg and lateral margin of foot
which branches of the femoral arteries supply most of the blood to the head of the femur
retinacular branches
the femoral artery goes through the ?? to become the ?? artery
adductor hiatus
popliteal
where does the iliopsoas insert
what merge to form it?
nerve supply?
lesser trochanter
psoas major and iliacus merge to form it
anterior rami of lumbar spinal nerves
insertion and attachment of sartorius
ASIS
superior part of proximal tibia
quadriceps femoris is composed of …
common attachment
rectus femoris
vastus lateralis
vastus medialis
vests intermedius
all attach distally onto patella (indirectly onto tibial tuberosity via patellar tendon)
innervation of quadriceps femoris
femoral nerve
where does pectineus originate and attach
superior ramus of pubis
> pectineal line of femur
vertebral levels that
psoas major
psoas minor
originate from?
psoas major - T12-L5
psoas minor - T12-L1
medial thigh - the ?? group
adductor
the most medial and most superficial thigh muscle
gracilis
nerve supply to adductors brevis and longus
obturator
nerve supply to gracilis
obturator
what is the hamstring part of the adductor magnus supplied by?
tibial nerve
the only exception to the medial compartment! all rest are obturator
femoral nerve
L2-L4
lymph from great saphenous vein goes to ….
lymph fro the small saphenous vein goes to ….
great saphenous > superficial inguinal > external iliac
small saphenous > popliteal > deep inguinal > external iliac
the external iliac artery becomes the femoral artery distal to the .. ?
inguinal ligament
medial and lateral circumflex arteries arise from the …
profunda femoris artery
supplies most of the blood to the head and neck of the semis
medial circumflex artery
muscle binding the popliteal fossa
superiomedially?
superiolaterally?
inferiorly?
superiomedially = semimembranosus and semitendonosus superiolaterally = biceps femoris inferiorly = gastrocnemius
what does the common fibular nerve wind around before it divides?
the fibular neck
tibial/common fib nerve > medial/lateral sural cutaneous nerve?
tibial > medial sural cutaneous nerve
common fib > lateral sural cutaneous nerve
nerve supply to the posterior leg
all supplied by tibial nerve
superficial muscles of posterior leg
attachment?
gastrocnemius
soleus
plantaris
attach to the posterior surface of the calcaneus via the calcaneus tendon
deep muscles of the leg
flexor hallicus longus
flexor digitorum longus
tibialis posterior
which is more medial - FHL or FDL
FDL
where does the FHL tendon insert?
base of the distal phalanx of the great toe
where do the FDL tendons insert?
bases of the lateral 4 distal phalanges
ankle jerk reflex
s1-2
fibular artery is a branch from the anterior/posterior tibial artery?
posterior tibial
what does the tibialis posterior tendon attach to?
medial tarsal bones
