1

What are the lateral and medial margins of the saphenous opening called respectively?

Lateral - Falciform margin, Medial - Cribriform fascia

The great saphenous vein drains into the femoral vein through what structure?

The saphenous opening

What covers the saphenous opening?

Loose connective tissue

4

What is the iliotibial tract (IT band) composed of?

A double layer of fascia

5

The IT tract runs from where to where?

Iliac tubercle to the anterolateral tibial tubercle (Gerdys tubercle)

6

The IT band serves as the aponeurosis for what muscles?

Tensor of fascia lata and Gluteus maximums

7

What is the function of the IT band?

Stabilizes the lateral hip and knee

8

What are the compartments of the thigh?

Anterior, medial, posterior

9

What do the intermuscular septa of the thigh arise from and what do they attach to?

Arise from fascia lata and attach to linea aspera

10

The medial intermuscular septum divides which two compartments?

Medial and anterior

11

The posterior intermuscular septum divides which two compartments?

Posterior and medial

12

The lateral intermuscular septum divides which two compartments?

Posterior and anterior

13

What are the three intermusuclar septa of the thigh?

Medial, posterior, lateral

14

What are the muscles of the anterior compartment and what is their innervation?

Extensors of knee, some flexors of hip, innervated by femoral nerve

15

What is the longest muscle in the human body?

Sartorius

16

What is the strongest muscle in the human body?

Quadriceps femoris

17

Name the muscles of the anterior compartment

Sartorius, Quadriceps femoris (rectus femoris, vastus lateralis, vastus medius, vastus intermedius), Iliopsoas, Pectineus (considered transitional between anterior and medial compartments)

18

What nerve and what spinal nerves does the patellar reflex test?

Femoral nerve, L2-L4

19

Where in the pelvic cavity should you look to find the femoral nerve?

The trough between the iliacus and psoas muscles

20

What would tightness of the iliopsoas muscle cause?

Increased lumbar curvature

21

Generally speaking, what are the functions of the muscles of the anterior compartment of the thigh?

Leg extension, kicking, supporting a bent knee position

22

What is the general function of muscles of the medial compartment of the thigh?

To adduct the thigh

23

What nerve innervates muscles of the medial compartment of the thigh?

Obturator nerve

24

What is the exception to the pattern of innervation amongst muscles in the medial compartment of the thigh?

The hamstring part of the adductor magnus is innervated by the sciatic nerve whereas all the others are innervated by the obturator nerve

25

Which adductor muscle is most deep?

Adductor magnus

26

What is the opening between the two parts of the adductor magnus called?

The adductor hiatus

27

What muscle has 4 openings for perforating veins?

Adductor magnus

28

What transmits the femoral vessels from the adductor canal to the popliteal fossa?

The adductor hiatus

29

What is the common tendon of insertion for three thigh muscles called, and what are the three thigh muscles?

Pes Anserinus. The muscles are gracilis, sartorius, and semi-tendinosus

30

What structure divides the subinguinal space, what does it divide the space into, and where is each subdivision?

Iliopectineal arch divides subinguinal space into muscular lacuna (lateral) and vascular lacuna (medial)

31

What is the iliopectineal arch composed of?

It is a thickening of iliopsoas fascia

32

Name the structure (excluding empty space) medial to the femoral artery and nerve and the structure medial to that structure

Rosenmuller lymph nodes are medial to femoral a and v, femoral ring is medial to the lymph node

33

Give the borders of the femoral triangle

Inguinal ligament (Superior), Sartorius (lateral), Adductor longus (medial)

34

What structures form the floor of the femoral triangle?

Iliopsoas and pectineus

35

What is the adductor canal and what are two other names for it?

It is an intermuscular passageway. Also known as subsartorial or Hunters canal

36

The adductor canal extends from where to where?

Apex of femoral triangle to adductor hiatus

37

What nerve is the saphenous nerve a branch of?

The femoral nerve

38

What nerve is the nerve to vastus medialis a branch of?

The femoral nerve

39

List the contents of the adductor canal

Femoral artery and vein, saphenous nerve, nerve to vastus medialis

40

Boundaries of the adductor canal

Vastus medius (lateral), Adductors longus and magnus (medially), Sartorius (roof), Vastoadductor fascia

41

What is the structure in the femoral triangle which is not in the femoral sheath?

The femoral nerve

42

What does the saphenous nerve innervate and what is unique about its course?

Skin on medial side of leg and foot, does not run through adductor hiatus

43

What keeps the femoral vessels in place in the femoral triangle?

The femoral sheath

44

What does the great saphenous vein pierce just inferior to the femoral triangle?

The femoral sheath

45

The femoral sheaths have septa which divide what from what?

Artery from vein and vein from lymphatics

46

Branches of the femoral artery

Superficial epigastric, superficial circumflex iliac, superficial and deep external pudendal arteries, deep artery of thigh (profunda femoris), popliteal artery (terminal branch)

47

Does the deep artery of the thigh run anterior or posterior to adductor longus?

Posterior

48

Branches of the deep artery of the thigh

Medial circumflex femoral (supplies head and neck of femur), Lateral circumflex femoral (gives ascending branch, descending branch, supplies muscles of lateral thigh), 4 perforating arteries (supply muscles of the 3 compartments)

49
