Flashcards in Superficial and Osseous Lower Limb Deck (37):
1

Starting distally, what is the path of the great saphenous vein?

Formed at the dorsal venous arch, ascends anteriomedially to the malleolus, passes medial femoral condyle posteriorly, transverses the crib form fascia, thru the saphenous opening, terminates with the femoral vein

2

Cribriform fascia

Fascia that covers the medial portion of the thigh, gives rise to the saphenous opening

3

What veins in the body have more valves?

Deep and inferior veins

4

What type of pump do the valves in the veins promote?

Musculovenous pump

5

Starting distally, what is the path of the small saphenous vein?

Formed from the lateral portion of the dorsal arch, ascends posterior to the lateral malleolus, passes the lateral border of the achilles tendon, up between the heads of the gastrocnemius, crosses deep fascia, empties into popliteal vein

6

Perforating veins

Veins that shunt blood from the superficial veins, across deep fascia, to deep veins. Have valves. Are compressed with muscle contraction.

7

Where are the vertical lymph nodes located?

Around the great saphenous

8

Where are the horizontal lymph nodes located?

Inferior to the inguinal ligaments

9

Meralgia Paresthetica

Impingement of the lateral femoral cutaneous nerve as it passes deep to the inguinal ligament. Usually caused from tight clothing or obesity

10

What 3 bones make up the pelvic bone?

Ilium, pubis, ischium

11

Where do the 3 pelvic bones converge?

Acetabulum

12

Ilium

Largest/most superior portion of pelvis

13

Ala

Broad wing-like posterolateral portion of the illium. Attachment site for muscles. 3 lines on lateral surface for gluteal muscles (Inferior, anterior, posterior). Iliac Fossa is medial on the ala.

14

Anterior Superior/Inferior Iliac Spines

Anterior. Attachment sites for ligaments and tendons of the lower limb

15

Iliac Crest

From ASIS to the PSIS. Attachment site for thin sheet-like muscles and deep fascia.

16

Iliac TUBERCLE

Thick portion of the iliac crest

17

Posterior superior iliac spine

Forms the skin dimple on some pts. Superior portion of the greater sciatic notch.

18

Auricular surface

"Ear-shaped" surface on the ilium. Articular surface for sacroiliac joint

19

Iliac TUBEROSITY

Superior to the auricular surface. Rough attachment point for strong ligaments of the SI joint.

20

Ischium

Postern-Inferior part of the hip bone. Posterior portion contributes to the inferior portion of the greater sciatica notch/lesser sciatic notch

21

Ramus of ischium

Joins to the inferior ramus of the pubis to form the ischiopubic ramus

22

Ischial Tuberosity

Junction of body and ramus. Origin of hamstrings.

23

Pubis

Anteromedial part of the hip bone.

24

Pubic tubercle

Medial attachment of the inguinal ligament

25

Obturator foramen

Oval opening in the hip bone. Has a membrane in the opening

26

Acetabulum

Cup-shaped cavity on the lateral aspect of the hip bone. Has a notch, lunate surface, and fossa

27

Femur

Longest/heaviest bone in the body

28

Fovea

Attachment site for ligament of the head of the femur (ligamentum teres femoris)

29

Angle of Inclination

Angle created by the neck vs the shaft of the femur. Gives leverage for hip abductors and rotators. Puts greater stress on bone near apex, so predisposes it to fracture.

30

Torsion Angle

Superior view of femur, axis of head and neck angles anteriorly while transverse axis of femoral condyles remains in flat coronal plane. Allows for rotary movements b/t head and acetabulum

31

Patella

Largest Sesamoid bone in the body

32

Tibia

Second largest bone in the body. Transmits all superior weight to the talus

33

Gerdy Tubercle

Attachment point of the IT band

34

Fibula

NOT WEIGHT BEARING. Serves as a muscle attachment site. Helps form the ankle joint.

35

Tibiofibular Syndesmosis

Attaches fibula and tibia

36

Bones of the feet

Talus, Calcaneus, Navicular, Cuboid, Cuneiforms, Metatarsals, phalanges

37

Largest and strongest bone of the foot

Calcaneus
