Superficial and Osseous Lower Limb Flashcards

1
Q

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

A

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

Q

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

A

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

Q

Perforating veins

A

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

Q

Ala

A

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.

16
Q

Iliac TUBERCLE

A

Thick portion of the iliac crest

17
Q

Posterior superior iliac spine

A

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

18
Q

Auricular surface

A

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

19
Q

Iliac TUBEROSITY

A

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

20
Q

Ischium

A

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

21
Q

Ramus of ischium

A

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

22
Q

Ischial Tuberosity

A

Junction of body and ramus. Origin of hamstrings.

23
Q

Pubis

A

Anteromedial part of the hip bone.

24
Q

Pubic tubercle

A

Medial attachment of the inguinal ligament

25
Q

Obturator foramen

A

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

26
Q

Acetabulum

A

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

27
Q

Femur

A

Longest/heaviest bone in the body

28
Q

Fovea

A

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

29
Q

Angle of Inclination

A

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
Q

Torsion Angle

A

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
Q

Patella

A

Largest Sesamoid bone in the body

32
Q

Tibia

A

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

33
Q

Gerdy Tubercle

A

Attachment point of the IT band

34
Q

Fibula

A

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

35
Q

Tibiofibular Syndesmosis

A

Attaches fibula and tibia

36
Q

Bones of the feet

A

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

37
Q

Largest and strongest bone of the foot

A

Calcaneus
