1
Q

location of prepatellar bursa and infrapatellar bursa

A

prepatellar - anterior to patella

infrapatellar - near tibial tuberosity

2
Q

longest vein in the body

A

great saphenous v

-embedded in superficial fascia for entire course

3
Q

describe the saphenous opening

A

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

4
Q

covers the saphenous opening

A

cribiform fascia

5
Q

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

A

falciform margin

6
Q

veins and arteries emerging through the saphenous opening

A

superficial epigastric
superfiical and deep external pudendal

the veins will all drain into great saphenous

7
Q

vasculature piercing through fascia lata slightly lateral to the saphenous opening

A

superficial circumflex iliac a and v

8
Q

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

A

lateral femoral cutaneous n

9
Q

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

A

intermediate femoral cutaneous n.

- branch of femoral n .

10
Q

nerve parallel to and slightly lateral to the great saphenous v

A

medial femoral cutaneous (branch of femoral)

11
Q

n supplies skin below the middle part of inguinal ligament

A

femoral branch of genitofemoral n.

12
Q

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

A

ilioinguinal n.

13
Q

what forms the patellar plexus

A

lateral femoral n
intermediate femoral cutaneous n
medial femoral cutaneous n

14
Q

deep fascia of thigh

A

fascia lata

15
Q

lateral thickening of fascia lata

A

iliotibial tract

16
Q

proximal attachments of fascia lata

A
  • 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
Q

forms roof of popliteal fossa

A

popliteal fascia

18
Q

what is the femoral sheath

A
  • 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
Q

structures which perforate through femoral sheath

A
  • great saphenous v
  • superficial branches of femoral a
  • femoral branch of genitofemoral n
20
Q

anterior wall of femoral sheath

A

extension of the transversalis fascia

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

21
Q

lateral compartment of femoral sheath

A

femoral a

femoral branch of genitofemoral n.

22
Q

middle compartment of femoral sheath

A

femoral v

23
Q

medial compartment of femoral sheath aka

A

femoral canal

  • contains loose areolar tissue and small lymph vessels and deep inguinal lymph nodes
  • site for femoral hernia
24
Q

base of femoral triangle

A

inguinal ligament

25
Q

direction of apex of femoral triangle

A

inferomedially

26
Q

forms medial border of femoral triangle

A

adductor longus

27
Q

is the femoral n a part of the femoral sheath

A

no

- lies between iliacus and psoas major muscles

28
Q

where does the femoral n end

A
  • about an inch below the inguinal ligament by breakin gup into its termina lm and cutaneous branches
29
Q

what n supplies pectineus m

A

n to pectineus m branching off femoral n.

30
Q

longest branch femoral n

A

saphenous n

31
Q

largest branch of femoral a

A

profunda fermoris (from its lateral side)

32
Q

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

A

deep external pudendal a

33
Q

superficial branches off the femoral a

A

superficial circumflex iliac a
supeficial epigastric a
superficial external pudendal a

34
Q

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

A

medial

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

35
Q

major vv contributing to femoral v

A

great saphenous v
deep external pudendal v
profunda femoris v

36
Q

roof of femoral triangle

A
  • skin
