Flashcards in Lecture: Thigh I/II - Butaric Deck (50):
1

pelvic girdle

os coxa and sacrum

2

what side of the femur is the linea aspera on?

posterior

3

medial lip of the linea aspera leads proximally to ...

pectineal line and spiral line

4

the lateral lip of linea aspera leads proximally to ...

gluteal tuberosity

5

demarcates boundary between tibia articular surface and patellar articular surfaces

medial and lateral sulcus meniscus

6

largest sesamoid bone

patella (froms within quadriceps femoris tendon)

7

lateral v. medial facet of the patella

medial - more shallow
lateral - larger and deeper

8

femur ossification

1 primary center (shaft)
4 secondary centers

9

femoral head present, but no greater trochanter

1-4 years

10

greater trochanter apparent, but open triradiate suture and no lesser trochanter

4-14 yrs

11

superficial fatty subcutaneous fascia

camper's fascia

12

deep membranous subcutaneous fascia

scarpa's fascia

13

investing fascia of thigh

fascia lata
- thickened laterally (IT band), thin medially

14

oval shaped opening in deep fascia, allows for passage of great saphenous v

saphenous hiatus (fossa ovalis)

15

innervation quadriceps fermoris

femoral nerve

16

only quad to flex the thigh

rectus femoris

17

non-quad anterior thigh muscles

- iliopsoas
- sartorius
- articularis genu

18

helps you sit cross legged

sartorius

19

makes sure synovial membrane of the knee doesn't get caught with flexion or extension

articularis genu

20

forms the medial border of femoral triangle

adductor longus

21

which neurovasculature structure is not part of the femoral sheath?

femoral n.

22

intermuscular tunnel for femoral neurovasculature

adductor (subsartorial) canal

23

the short head of biceps femoris is grouped with but technically not a hamstring. why not?

doens't extend the thigh, different innervation, different attachment

24

lumbar plexus levels

L1-L4 ventral primary rami


all the plexuses are ventral primary rami not dorsal (just goes to the back)

25

posterior divisions of lumbar plexus

lateral femoral cutaneous n.
femoral n.

** typically extensors and abductors

26

anterior division of lumbar plexus

ilioinguinal and iliohypogastric n
genital femoral n.
obturator n
lumbosacral trunk n.

*** typically flexors, adductors

27

root ilioinguinal and iliohypogastric n.

L1

28

root genital femoral n.

L1-2

29

root lateral femoral cutaneous n.

L2-3

30

root femoral n.

L2-4

31

root obturator n.

L2-4

32

root lumbosacral trunk

L4-5

33

tingling, numbness, or burning in lateral thigh

entrapment of lateral femoral cutaneous n.

34

sacral plexus roots

(L4) L5-S4

35

tibial n root

L4-S3

36

where does the tibial n. come from

tibial n.
L4-S#
anterior division of sacral plexus

37

where does the common peroneal n. come from

L4-S2
posterior division of sacral plexus

38

lumbosacral trunk root

L4,L5

39

inferior gluteal n. root

L5 S1,2

41

posterior femoral cutaneus n. root

S1-S3
** mixed anterior and posterior

42

sciatic n. root

L4-S3

43

pudendal n. root

S2-S4

44

anterior v. posterior branch of obturator n.

posterior - muscular
anterior - muscular and cutaneous

45

posterior v. anterior divsions of plexuses general rules

posterior: typically extensors, abductors, everters
anterior: typically flexors, adductors, inverters

46

motor to short head biceps femoris

common peroneal n.

47

where is the inferior cluneal branch? ***

- comes off the posterior femoral cutaneous n.
- supplies sensory to transverse gluteal line
- the other cluneal nerves come from dorsal primary rami (inferior comes from ventral)

48

cruciate blood supply to hip joint

superior: inferior gluteal
medial: medial femoral circumflex
lateral: lateral femoral circumflex
inferior: 1st perforating a.

all but superior come from profunda femoris,

form a cross-shaped anastomosis

49

main blood supply to femoral head

medial femoral circumflex

50

which genicular a. goes into the knee joint?

middle genicular a.
