Fascia Lata

Question 1

What is fascia

Answer 1

A sheet or band of fibrous tissue lying deep to skin that lines, invests and separates structures within the body

Question 2

What is superficial fascia

Answer 2

Blends with reicular layer beneath the dermis

Question 3

What is deep fascia

Answer 3

Envelopes muscles, bones and neurovascular structures

Question 4

What is visceral fascia

Answer 4

Provides membranous investments that suspend organs within their cavities

Question 5

Where does the fascia lata begin

Answer 5

Around the iliac crest and inguinal ligament

Question 6

Where does the fascia lata end

Answer 6

Distal to the bony prominences of the tibia where is becomes the deep fascia of the leg (crural fascia)

Question 7

Where is the fascia lata thickest

Answer 7

Along superolateral aspect of thigh

Question 8

Where is the fascia lata thinnest

Answer 8

Wehere it covers adductor muscles of medial thigh

Question 9

What divides thigh musculature into three compartments

Answer 9

Intermuscular septa from fascia lata attaching to femur

Question 10

Which is the strongest intermuscular septa

Answer 10

Lateral intermuscular septa due to reinforcement from iliotibial tract

Question 11

Where is the saphenous opening

Answer 11

In the fascia lata just inferior to inguinal ligament

Question 12

What is the saphenous opening for

Answer 12

Serves as an entry point for efferent lymphatic vessels and great saphenous vein

Question 13

What covers saphenous opening

Answer 13

Cribriform fascia

Question 14

Where does the cribriform fascia develop from

Answer 14

Falciform margin

Question 15

What is the iliotibial tract

Answer 15

Longitudinal thickening of fascia lata. Strengthened posteriorly by fibres from gluteus maximus

Question 16

Where is the iliotibial tract

Answer 16

Lateral in the thigh

Extends from iliac tubercle to lateral tibial condyle

Question 17

What are the main functions of the illiotibial tract

Answer 17

Movement
Compartmentalisation
Muscular sheath

Question 18

What are the movement functions of the iliotibial tract

Answer 18

Acts as extensor, abductor and lateral rotator of hip

Provides lateral stabilisation to knee joint

Question 19

How does the iliotibial tract aid in compartmentalisation within the thigh

Answer 19

Deepest aspect extends centrally to form lateral intermuscular septum and attaches to femur

Question 20

What muscle does the iliotibial tract as a sheath for

Answer 20

Tensor fascia lata muscle

Question 21

What is the action of the tensor fascia lata

Answer 21

Flexor, abductor and internal rotator of the hip

Tenses fascia lata

Question 22

Where does tensor fascia lata originate

Answer 22

Iliac crest

Question 23

Where does tensor fascia lata insert

Answer 23

Anterior aspect of iliotibial tract at the junction of the upper and middle thirds of the thigh

Question 24

What is the purpose of tightening the fascia lata

Answer 24

Forces muscle groups closer together which centralises muscle weight and limits outward expansion which reduces overall force required for movement at hip joint
Makes muscle contraction more efficient in compressing deep veins

Question 25

What proximal attachments does the fascia lata have

Answer 25

Sacrum and coccyx
Iliac crest
Inguinal ligament
Superior pubic rami
Inferior ischiopubic rami
Ischial tuberosity
Sacrotuberous ligament

Question 26

Where does the deep iliac fascia blend with fascia lata

Answer 26

After covering iliacus and psoas

Question 27

Where does superficial fascia blend with fascia lata

Answer 27

Just below inguinal ligament

Question 28

Where iliotibial tract attach distally

Answer 28

Lateral tibial condyle
