Anterior and Medial Thigh Flashcards
Function of the deep fascia of the thigh
helps return blood to the heart when lower extremities are contracting.
Anterior thigh muscles
iliopsoas, sartorius, quadriceps femoris
Origin of iliopsoas and insertion.
O psoas: vertebral body and transverse processes of T12-L5
O illiacus: iliac crest, iliac fossa
I: lesser trochanter of femur
Action of the iliopsoas
flex the thigh and bend the body of the trunk
Origin of the sartorius, and insertion.
O: ASIS
I: medial surface of tibia (part of pes anserinus)
Functions of sartorius
flex, abduct, and laterally rotate, flex and sit cross legged
Sartorius innervated by
femoral nerve
Bursae at the knee
prepaterllar
suprapatellar
subcutaneous infrapatellar
deep infrapatellar
What bursitis is associated with kneeling for an extended amount of time?
prepatellar bursitis or nun’s knee
Charley horse and hip pointer
contusion of the quads
contusion of iliac crest
Runners knee is aka
chondromalacia patellae
Patellar dislocations are almost always
lateral
Medial thigh muscles
adductor longus, brevis and magnus gracilis
Innervation of the medial thigh muscles
obturator nerve
Origin of adductor longus and insertion
O: body of pubis
I: mid 1/3 of medial linea aspera
Adductor brevis origin and insertion
O: inferior ramus of pubis
I: proximal linea aspera
Origin of adductor magnus and insertion
O: inferior pubic ramus and ischial tuberosity
I: linea aspera, medial supracondylar line and adductor tubercle
Origin of the adductor magnus hamstring part and insertion
O: ischial tuberosity
I: adductor tubercle on femur
Functions of adductor magnus hamstring part
extends thigh
Innervation of adductor magnus hamstring part
tibial nerve
Origin of gracilis and insertion
O: inferior ramus of pubis
I: superior/medial surface of tibia
What muscle is often used for transplantations on the hand or external anal sphincter?
gracilis
What does the obturator externus do?
steadies the femur head in the hip joint
Pes Anserinus is made up of what three muscles and three nerves and is on the medial surface of the tibia?
sartorius gracilis semitendinosus femoral nerve obturator nerve sciatic nerve
Femoral triangle has an opening just below the inguinal ligament called..
saphenous opening or hiatus
The femoral triangle saphenous opening is covered by a connective tissue called…
cribriform fascia
Why is the femoral triangle clinically important?
palpate the femoral artery
compress the femoral artery against superior ramus of pubic bone.
put catheter into femoral artery for a left cardiac angiography or vein for right cardiac angiography
femoral vein puncture for fluid infusion
Femoral nerve cutaneous branches to…and terminates to …
anterior medial thigh
saphenous nerve
Femoral artery branches
deep artery of the thigh to medial and lateral circumflex femoral arteries
Inguinal ligament is what dermatome?
L1
Skin anterior to patella and over medial malleolus are what dermatome?
L4
Lateral malleolus is what dermatome?
S1
