1
In what direction do the upper and lower limbs rotate during development?
laterally and medially respectively
2
Inferiorly, the fascia lata is continuous with what?
cural fascia of the leg
3
What is the lateral thickening of the fascia lata called?
Iliotibial tract
4
What muscles have a conjoint aponeurosis that forms the tensor fascia lata and gluteus maximus muscles?
Iliotibial tract
5
What specialized fascia overlies the origin of the gluteus medius muscle?
Gluteal aponeurosis
6
What role does the fascia lata play in making sure that blood from the legs is returned to the heart?
It prevents muscles from bulging outwards so that they squeeze the deep veins of the leg that are under the fascia to return blood to the heart
7
What is the role of perforating veins?
They connect the superficial an deep veins of the leg
8
Why are perforating veins important for getting blood back to the heart?
They move blood from superficial veins (great saphenous and lesser saphenous) into the deeper femoral vein which is under the fascia lata and is compressed by muscles moving the blood towards the heart
9
The great saphenous vein carries blood from __________ to ____________?
Dorsal venous arch on the foot to the femoral vein in the femoral triangle
10
What two veins join to create the great saphenous vein?
dorsal vein of the great toe and the dorsal veinous arch
11
What two structures merge to form the small saphenous vein?
dorsal vein on the small toe and the dorsal venous arch
12
What happens when perforating veins fail to shunt blood to the deep venous system?
Causes superficial veins to enlarge, making valves deficient
13
T or F: valves are more numerous in superficial veins than deep veins?
False
14
What causes varicose veins?
Valve deficiencies from enlarged veins allow the blood to flow backwards
15
What are the four compartments of the lower extremity?
anterior, posterior, medial, and gluteal compartments
16
In general what is the function of the muscles in the anterior compartment of the knee?
Knee extension and hip flexion
17
In general what is the function of the muscles in the medial compartment of the knee?
adduction and medial rotation, some hip hip flexion
18
In general what is the function of the muscles in the posterior compartment of the knee?
Flexion of the knee, extend hip, medial/lateral rotation
19
In general what is the function of the muscles in the gluteal compartment of the knee?
Extension of the hip and adbuction
20
What separates the vastus lateralis from the biceps femoris?
Lateral intermuscular septum
21
Where does the lateral intermuscular septum exten from and attach to?
from iliotibial tract to the lateral lip of the linea aspera
22
What lies between vastus medialis and the adductor group?
Medial intermuscular septum
23
Where does the medial intermuscular septum attach?
medial lip of the linea aspera
24
What is sandwiched by the adductor magnus and the semimembranosus muscle?
Posterior intermuscular septum
25
What innervates the muscles of the gluteal/lateral compartment?
direct branches of the lumbosacral plexus
26
What innervates the muscles of the anterior compartment?
femoral N (except psoas major)
27
What is the primary innervation of the medial compartment?
obturator N
28
What is/are the primary innervation of the posterior compartment?
tibial N, and common fibular N (components of sciatic N)
29
What innervates the iliopsoas muscle?
ventral rami L1-L3
