1

lower limb joint?

acetabulum
-less mobility, more stability

2

capsule of hip joint?

limits extension and abduction

does little to inhibit flexion

3

what allows for actions of climbing and running?

modified hinge at knee and flexion at hip

4

fibula role?

little to add stability and strength
-mainly for muscle attachments

5

ankle allows?

hinge joint to jump and run coupled with muscles strong enough to elevate the entire body mass

6

multiple joints in feet allow?

spring needed for cushioned landing and for negotiating uneven surfaces

7

tela subcutanea

superficial fascia of lower limb

8

two layers of superficial fascia ?

fatty and membranous layer

9

whats between fatty and membranous layer?

inguinal lymph nodes
subQ blood vessels and nerves

10

deep fascia of lower limb?

stocking like investment

11

attachments of deep fascia?

above to most of the inferior aspect of bony pelvis and attached to bony prominences at knee and ankle

12

fascia lata

continuity of deep fascia
-most superior portion of deep fascia
-surrounds thigh and portion of gluteal region

13

gluteal aponeurosis

thickened portion of fascial lata
-extends inferiorly from posterior portion of iliac crest and forms an incomplete intermuscular septa between gluteus maximus and medius

14

what muscles is gluteal aponeurosis between?

gluteus maximus
gluteus medius

15

intramuscular septa

lateral and medial when part of fascia lata

inward projections of fascia lata which extend to femur and delineate muscular compartments

16

iliotibial tract

lateral thickening of fascia lata
-serves as tendon for tensor facia lata and gluteus maximus

attaches inferiorly to tibia, head of fibula and blends with capsule of knee joint

17

saphenous vein opening

circular opening in superior anteromedial portion of the fascia lata below the inguinal ligament

-transmits the great saphenous vein

18

falciform margin

sickle shaped and part of saphenous vein opening

underlain with fascia cribrosa

19

crural fascia

extension of fascia lata below knee

20

intermuscular septa

anterior and posterior (when part of crural fascia)
-attach as inward extensions of crural fascia to fibula

-delineate anterior and lateral crural compartments

transverse
-attaches between tibia and fibula posteriorly
-delineate superior and deep posterior compartments

21

retinacula

thickening of crural fascia at ankle which prevents tendons from bowstringing

-superior and inferior extensor retinacula (anterior)
-superior and inferior fibular retinacula (lateral)
-flexor retinacula - posteromedial

22

fascia of dorsum of foot?

continous with extensor retinacula

23

plantar fascia

continuation of fascia of dorsum of foot onto the sole
thickened central portion - plantar aponeurosis

24

plantar aponeurosis

thickened central portion of plantar fascia

25

anterior femoral compartment

quads and sartorious
-flex thigh and/or extend leg

26

artery and nerve in anterior femoral compartment?

femoral artery and nerve

27

femoral triangle

transitional space between abdominopelvic region and the lower limb

bounded by inguinal ligament, sartorious, adductor longus muscles, and covered by fascia lata

28

contents of femoral triangle?

femoral vein, artery, nerve, and deep inguinal lymph nodes

29

medial femoral compartment?

muscles within this compartment flex, adduct, and rotate the thigh

branches of obturator artery and nerve distribute within this compartment

30

adductor canal

canal connecting femoral triangle with popliteal fossa

-bounded by adductor musculature, vastus medialis, and sartorious
