Fascia of the Thigh Flashcards
1
Q
Subcutaneous fascia
A
o Covers entire thigh
o Continuous with subcutaneous fascia of the entire anterior abdominal wall, gluteal region and leg
o Divided into 2 layers: Superficial (fatty) and deep (membranous)
2
Q
Deep (membranous) subcutaneous fascia of the thigh
A
- Attached to fascia lata just distal to the inguinal ligament and along the upper and medial areas of the thigh
- Also attached to saphenous opening (ovalis) and fills the opening with tissue called the fascia cribrosa
- A large bursa is found in the subcutaneous fascia over the patella
3
Q
Fascia lata
A
o External layer of investing fascia of the thigh
o Thick laterally, thin medially
4
Q
3 medial attachment sites for fascia lata
A
Remember: fascia lata is THIN medially
- Ischial tuberosity
- Ischiopubic ramus
- External perineal fascia
5
Q
Fascia lata is continuous with
A
- Thoracolumbar fascia (proximally
- External abdominal fascia (proximally)
- Investing fascia of the leg (distally)
6
Q
3 anterior attachment sites for fascia lata
A
- Pubic tubercle
- Inguinal ligament
- ASIS
7
Q
Fascia lata over femoral vessels
A
- The fascia lata is thickened and has an opening - the saphenous opening (“fossa ovalis”)
- This serves as passage way for the great saphenous vein
- Falciform margin is the free lateral margin of the saphenous opening
- Lateral portion is very thick and buttressed by fibers of tendons (gluteus maximus and tensor fascia latae)
8
Q
2 superior attachment sites of fascia lata
A
- Crest of ilium
- Dorsal sacrum
9
Q
IT band
A
- Iliotibial band is a thickened tendon within the fascia lata
- Located on lateral surface of the thigh
10
Q
Tensor fascia latae muscle
A
Found between the two layers of the fascia lata laterally
11
Q
Posterior fascia lata
A
- Formed by fusion of two layers of gluteal fascia
- Lateral and medial intermuscular septa
- Connects under surface of fascia lata with linea aspera
- Divides thigh into 3 myofascial compartments
