Flashcards in Lab 20-22: Anterior Thigh Deck (42):
1

location of prepatellar bursa and infrapatellar bursa

prepatellar - anterior to patella
infrapatellar - near tibial tuberosity

2

longest vein in the body

great saphenous v
-embedded in superficial fascia for entire course

3

describe the saphenous opening

opening in the fascia lata inferior to the medial part of the inguinal ligament, about 4 cm inferolateral to the pubic tubercle

4

covers the saphenous opening

cribiform fascia

5

the superior, lateral and inferior borders of the saphenous opening form a crescent shaped edge called

falciform margin

6

veins and arteries emerging through the saphenous opening

superficial epigastric
superfiical and deep external pudendal

the veins will all drain into great saphenous

7

vasculature piercing through fascia lata slightly lateral to the saphenous opening

superficial circumflex iliac a and v

8

n. pierces fascia lata about 10 cm below the ASIS and supplies skin on anterior and lateral aspect of thigh

lateral femoral cutaneous n

9

n. pierces fascia lata about 8-10 cm below the inguinal ligament b/w lateral femoral cutaneous n and great saphenous v

intermediate femoral cutaneous n.
- branch of femoral n .

10

nerve parallel to and slightly lateral to the great saphenous v

medial femoral cutaneous (branch of femoral)

11

n supplies skin below the middle part of inguinal ligament

femoral branch of genitofemoral n.

12

n supplying mainly the scrotum or labium majus and some adjacent regions of thigh

ilioinguinal n.

13

what forms the patellar plexus

lateral femoral n
intermediate femoral cutaneous n
medial femoral cutaneous n

14

deep fascia of thigh

fascia lata

15

lateral thickening of fascia lata

iliotibial tract

16

proximal attachments of fascia lata

- laterally to the anterior part of the iliac crest, anteriorly to inguinal igament, medially to pubis and ischial tuberosity
- posteriorly continuous with fascia of the gluteal region

17

forms roof of popliteal fossa

popliteal fascia

18

what is the femoral sheath

- extension of transversalis fascia
- funnel shaped fascial tue that invests the proximal one or two in of the femoral vessels
- proximally the funnel opens into the abdomen and distally surrounds vessels and blends with their outer walls

19

structures which perforate through femoral sheath

- great saphenous v
- superficial branches of femoral a
- femoral branch of genitofemoral n

20

anterior wall of femoral sheath

extension of the transversalis fascia
posterior wall is continuation of fascia over iliacus and psoas major muscles

21

lateral compartment of femoral sheath

femoral a
femoral branch of genitofemoral n.

22

middle compartment of femoral sheath

femoral v

23

medial compartment of femoral sheath aka

femoral canal
- contains loose areolar tissue and small lymph vessels and deep inguinal lymph nodes
- site for femoral hernia

24

base of femoral triangle

inguinal ligament

25

direction of apex of femoral triangle

inferomedially

26

forms medial border of femoral triangle

adductor longus

27

is the femoral n a part of the femoral sheath

no
- lies between iliacus and psoas major muscles

28

where does the femoral n end

- about an inch below the inguinal ligament by breakin gup into its termina lm and cutaneous branches

29

what n supplies pectineus m

n to pectineus m branching off femoral n.

30

longest branch femoral n

saphenous n

31

largest branch of femoral a

profunda fermoris (from its lateral side)

32

a running medially across the pectineus and adductor longus m to pierce the deep fascia and supply the scrotum or labium majus

deep external pudendal a

33

superficial branches off the femoral a

superficial circumflex iliac a
supeficial epigastric a
superficial external pudendal a

34

the femoral v is _____ to a at the apex of femoral triangle

medial
- maintains this relationship unti lit disappears behind inguinal ligament to become external iliac v

35

major vv contributing to femoral v

great saphenous v
deep external pudendal v
profunda femoris v

36

roof of femoral triangle

- skin
- superficial fascia (w superficial inguinal lymph nodes)
- deep fascia (including cribiform fascia)
- superficial n and vessels

37

muscles forming floor of femoral triangle

adductor longus
pectineus
psoas major
iliacus

38

plexus of nerves below sartorius

subsartorial plexus
- saphenous n
- anterior division of obturator n
- medial femoral cutaneous n

39

last branch of femoral a before it exits the adductor canal

descending genicular a

40

terminal branches of descending genicular a

saphenous a
articular branch

41

three branches off the lateral femoral circumflex

- ascending branch [goes under tensor fascia latae to supply hip joint]
- transverse branch
- descending branch [courses inferiorly to supply quads and capsule of knee joint]

42

describe the two heads of rectus femoris

- straight head arises from the AIIS
- reflected head arises from above the acetabulum
