Anterior and medial thigh Flashcards
This group of veins travels deep to the deep fascia with the major arteries
The deep group of veins
Do the deep veins contain more or less valves that the superior veins?
The deep veins have more valves than the superficial veins
What are the 3 main superficial veins of the leg?
- Great saphenous v
- Small saphenous v
- Dorsal venous arch
What 2 veins form the great saphenous vein?
- Dorsal vein of the big toe
- Dorsal venous arch
What does the great saphenous vein drain into? and where?
Femoral vein at the Saphenous opening
What 2 veins form the small saphenous vein?
- Dorsal vein of the small toe
- Dorsal venous arch
What does the small saphenous vein drain into? (and where)
The popliteal vein after crossing the popliteal fossa
What 2 factors aid in venous return of the deep veins?
- Pulsations from the arteries
- Compression of muscles
These veins piece the deep fascia and only allow blood to travel from superficial to deep
-valves are present here
Perforating veins
This type of fascia invests the lateral extensors of the leg
Deep fascia
_______ of the fascia lata seperates compartments of the thigh
Fibrous septa
What are the 3 compartments of the thigh?
-Anterior, medial, and posterior
What are the attachments for the fascia lata
- Inguinal ligament
- Pubic arch
- Body of pubis
- Pubic tubercle
-Iliac crest
- Sacrum
- Coccyx
- Sacrotuberous ligament
- Ischeal tuberosity
What is the long, thickened lateral component of the fascia lata
Iliotibial tract
What does the IT tract enclose?
- Tensor fascia lata
- gluteus maximus
Where does the IT tract insert?
Gerdys tubercle (on the lateral condyle of the tibia)
Where is the saphenous opening in relation to the inguinal ligament?
Inferior to the inguinal ligament
What structure passes through the saphenous opening?
Great saphenous vein (then dumps into the femoral vein)
This is the deep fascia of the leg and it is continuous with the fascia lata
Crural fascia
What 2 things divide the leg into 3 compartments?
- Crural fascia
- Interosseous membrane
What 3 compartments does the crura fascia and the interosseous membrane divide the leg into?
Anterior, lateral, and posterior
This is a continuation of the deep fascia on the sole of the foot
-central location is very thick
Plantar aponeurosis
What kind of fascia covers the dorsum of the foot?
Thin fascia
The gluteal fascia blends together with the…
Fascia lata
What are the boundaries of the femoral triangle?
- ASIS–> Pubic Tubercle
- Inguinal ligament
- Sartorius
- Adductor longus
What is the roof of the femoral triangle
The fascia lata
What comprises the floor of the Femoral triangle?
- Iliopsoas m
- Pectineus
What are the contents of the femoral triangle?
NAVEL
- Femoral nerve
- Femoral artery
- Femoral vein
- Empty space
- Lymphatics
What is the femoral sheath and extension of?
Transversalis fascia and the fascia covering the iliopsoas muscle
What does the femoral sheath contain?
The femoral artery and vein and empty space
Is the femoral nerve contained in the femoral sheath?
NOOOOOOOOOO
What structure of the femoral sheath is most lateral?
Femoral artery
What structure of the sheath is intermediate
Femoral vein
What is the medial most part of the femoral sheath
Femoral canal (empty space)
This is the name of the superior opening of the femoral canal
The femoral ring
What are the ligament boundaries of the femoral canal? (3)
- Inguinal ligament (anterior)
- Lacunar ligament (medial)
- Pectineal ligament (posterior)
RECAP- Name the components of the femoral sheath from lateral to medial
- Femoral artery
- Femoral vein
- Femoral canal (empty space)
- Lacunar ligament
