Anterior/Medial Thigh Flashcards
Thick, deep fascia of the thigh. Superiorly attached to the pelvin, Scarpa’s fascia, and inguinal ligament
Fascia lata
thickened fascia of the external oblique muscle
inguinal ligament
Bone features the inguinal ligament runs between (2)
1) anterior superior iliac spine
2) pubic tubercle
What three important structures pass below the inguinal ligament?
femoral vein, artery, and nerve
Thickened lateral part of the fascia lata
iliotibial tract
Two functions of the iliotibial tract
1) helps keep knee extended
2) provides lateral stability when standing
Where does the iliotibial tract attach to above and below, respectively?
ilium and lateral condyle of tibia
Iliotibial (IT) Band Syndrome
Tear of IT tract due to overexertion (contraction of tensor fascia lata, gluteus maximus)
Oval shaped defect in deep fascia, allow for passage of great saphenous vein
saphenous opening
location of saphenous opening (what is it inferior and anterior to)
Inferior to inguinal ligament, anterior to femoral artery/vein
Falciform margin
sharp edged lateral side of the saphenous opening
Clinical significance fo the saphenous opening
site of bulge in femoral hernia
Four compartments of the thigh
1) anterior
2) posterior
3) medial
4) lateral
Muscle actions of the anterior compartment of the thigh (2)
1) extend knee
2) some do hip flexion
Muscle actions of the posterior compartment of the thigh (2)
1) flex knee
2) some extend hip
Muscle action of the medial compartment of the thigh
adduct hip
Muscle action of the lateral compartment of the thigh
abduct hip
Nerve associated with anterior compartment of the thigh
femoral nerve
Nerve associated with posterior compartment of the thigh
tibial part of sciatic nerve
Nerve associated with medial compartment of the thigh
obturator nerve (1 exception)
Nerves (2) associated with lateral compartment of the thigh
superior and inferior gluteal nerves
Insertion of quadriceps muscles
patella
Four quadriceps muscles
1) rectus femoris
2) vastus medialis
3) vastus lateralis
4) vastus intermedius
Which of the quadriceps muscles cross both the hip and kneejoint
rectus femoris
Inferior tendon attached to the patella
patellar tendon
What do tendons link to what?
muscle to bone
What do ligaments link to what?
bone to bone
Origin of the quadriceps muscles
Rectus femoris is the anterior inferior iliac spine. The rest are the femur
Purpose of the patella
mechanical advantage of the quadriceps
What does the patellar tendon reflex test?
L2-L4 (Femoral Nerve)
Action(s) of the sartorius
flex hip and flex knee
Tailor sitting is a textbook example of the action of which muscle
sartorius
Origin of the sartorius muscle
anterior superior iliac spine
What is a hip pointer?
Contusion of muscles at anterior superior iliac spine
Insertion of the sartorius muscle
tibia
