Unit 3- Fascia and Veins Flashcards
The subcontaneous tissue of the hip and thigh is continuous with:
inferior abdominal wall and buttock
What happens to the subcutaneous tissue at the knee?
it loses its fat and blends with the deep fascia
The deep fascia is ____ and ___ and invests the:
strong
inelastic
lower extremity
The deep fascia limits outward expansion of the:
It causes increased ____ which does:
contracting musculature
pressure which “pumps” the blood proximally through the veins
The fascia lata attaches to and is continuous with
the inguinal ligament, pubic arch, body of the pubis and pubic tubercle
Iliac crest
scarpa’s fascia
sacrum, coccyx, sacrotuberous ligament, iscial tuberosity posteriorly
exposed parts of bones at the knee and deep fascia of the leg
What does Scarpa’s fascia attach to?
deep LE fascia inferior to the inguinal ligament
What does the fascia lata enclose?
the large thigh muscles
The fascia lata laterally forms the:
iliptibial tract
Thickened fascia lata that forms the aponeurosis of the tensor of the fascia lata and gluteus maximus
Iliotibial tract
The facia lata extends from”
iliac tubercle to anterior-lateral tibial tubercle (Gerdy)
Where does the lateral intermuscular septa run?
from the iliotibial tract to the lateral lip of the linea aspera & lateral supracondylar line of the femur
Facial compartments of the thigh
Lateral intermuscular septa
medial inermuscular septa
posterior intermuscular septa
the fascial compartments of the thigh are surrounded by:
facia lata and 3 intermuscular septa, formed by deep extensions of the fascia lata connecting to the linea aspera of the femur
A gap in the fascia lata infero-lateral to the inguinal ligament, lateral to the pubic tubercle
Saphenous opening
Medial margin of the saphenous opening is (SMOOTH/SHARP)
smooth
Lateral margin of the saphenous opening is:
sharp forming the falciform ligament
A sieve like membrane covering the saphenous opening except for an opening for the great saphenous vein and lymphatics
Cribiform fascia
The deep fascia to the leg is continuous with the:
fascia lata
and the periosteum
Deep fascia to the leg
Crural fascia
the crural fascia attaches to the:
anterior and medial borders of the tibia
The crural fascia is (THINNER/THICKER) distally. It (THINS/THICKENS) to form:
thinner
thickens
an extensor flexor retinaculum both ant and post to the ankle
The anterior and posterior intermuscular septa pass from:
the deep crural fascia to attach to the margins of the fibula
The interosseous membrane transverses from:
tibia to fibula
3 compartments created by the crural fascia
Anterior
Lateral
Posterior
Anterior compartment contains
dorsiflexors
Lateral compartment contains
fibular (everter) compartment
Posterior compartment contains
plantar flexors
The transverse intermuscular septum divides the ____ into a deep and superficial compartment
transverse intermuscular septum
Deep veins accompany:
the arteries
Superficial veins
Great and small saphenous veins
The great saphenous vein is formed by:
the union of the dorsal digital vein of the great toe and the dorsal venous arch
Pathway of the great saphenous vein:
ascends ant to the medial malleolus
post to the medial condyle of the femur
The great saphenous vein freely anastomoses with the:
great saphenous vein
Proximally, the great saphenous vein transverses the:
saphenous opening in the fascia to enter the femoral vein
The small saphenous vein is formed by:
the union of the dorsal digital vein of the 5th digit and distal venous arch
The small saphenous vein runs posterior to:
and lateral to:
lateral malleolus
lateral to the calcaneal tendon
The small saphenous vein runs superiorly medial to the:
fibula
The small saphenous vein penetrates:
the deep fascia of the popliteal fossa
It ascends between the heads of the gastrocnemius muscle to join the popliteal vein
Perforating veins penetrate:
the deep fascia
Perforating veins are tributaries of:
the saphenous veins
valves of the perforating veins are located where?
just distal to penetration of the deep fascia
the perforating veins cross the _____ ____ obliquely
why?
deep fascia
so that muscle contractions cause valves to close prior to venous compression so blood is forces proximally (musculo-venous pump)
Deep veins are usually paired and run with:
this allows:
named arteries inside a vascular sheath
arterial pulsation to force blood proximally
What does the popliteal vein join? Where?
Femoral vein
in the popliteal fossa
The femoral vein is joined by:
the deep vein of the thigh
The femoral vein passes deep to:
the inguinal ligament to become the external iliac vein
