1

What three things make up the pelvic girdle?

Ilium, Ischium, Pubis

made up of to coxae (hip or innominate bones)

2

What three things form the pelvis?

sacrum, coccyx, and pelvic girdle

24

Meniscus is composed of what

-Semilunar cartilages

-medial- "C shaped"

-lateral- "O shaped"

-only 3-5mm thick on average

25

Functions of the meniscus

absorbs shock/jolts

improve stability of tibiofemoral joint

-deepens the condylar surface

26

Which part of the meniscus is more firmly attached?

the medial meniscus is more firmly attached than the lateral

27

meniscotibial (coronary) ligaments

?

28

Why do lesions occur?

it is a result of femoral rotation with foot planted (fixed tibia)

29

With a cross-sectional appearance, menisci are wedged shaped and have three zones. What are they?

red zone (highly vascular)

red-white zone (mild vascularity)

white zone (avascular)

30

What are the three types of knee alignments?

genu varum "bow legged"

genu valgum "knock knees"

genu recurvatum "hyperextension"

31

What are the 7 tarsal bones?

Talus

Calcaneus

Navicular

Cuboid

Lateral, intermediate & medial cuneiforms

48

Landmarks of the proximal femur

-Femoral head

-Fovea capitis

-Femoral neck

-Greater trochanter

-Lesser trochanter

-Intertrochanteric crest

49

Attachment site for fovea capitis

50

Fovea capitis

card image

51

Landmarks of the distal femur

-linea aspera

-adductor tubercle

-medial & lateral epicondyles

-medial & lateral condyles

52

What do the medial and lateral condyles of the femur articulate with

Tibia

53

Advantages of a sesamoid bone ("free-floating")

Improves leverage of quadriceps and their ability to extend knee

54

what is the patella embedded in

Within the quadriceps and patellar tendon

55

Kansas patella fracture, how did it occur?

the rectus femurs tendon and patellar tendon tore causing the patella to shatter

56

Proximal end of tibia expands into

-Tibial Plateau

-Medial and lateral condyles

-Tibial tuberosity

-Pes anserine

-Gerdy's tubercle

57

Distal end of tibia forms into

medial malleolus

58

Insertion site of quadriceps

Tibial tuberosity

59

Limited weight-bearing during movement

Lateral Malleolus Property

60

What 3 muscles insert at the pes anserine

-sartorius

-gracilis

-semitendinous

61

What band inserts at the Gerdy's tubercle?

Iliotibial band (IT)

continuation of the quadriceps tendon

67

tibia and fibula articulates with what bone

talus

68

-weight bearing bone

69

Navicular location

71

Property of the metatarsals

form the arches of foot with ligamentous and muscular support

72

Property of the phalanges

-each toe has has 3 phalanges (proximal, middle, distal) except big toe/first digit

-first digit only has a proximal and distal phalanx
