Flashcards in Biomechanics And Kinesiology - The Knee Deck (26):
1

Bursae

- fluid filled structure
- under high pressure reduces friction

2

Pes anserinus

- where tendons of sartorius, gracilis and semitendinosus meet

3

Iliotibial band

- strong band of tissue connecting tensor fasciae latae to femur and tibia

4

Functions of menisci

- increase contact area between femur and tibia, reducing the stress on articular cartilage
- knee joint lubrication
- joint stabilization

5

Tibial-on-femoral perspective

- tibia will move while the femur is relatively stable

6

Femoral-on-tibial perspective

- femur will move while the tibia is relatively stable

7

Anterior cruciate ligament

- prevents the femur sliding posteriorly on the tibia
- prevents the tibia from sliding anteriorly on the femur

8

Posterior cruciate ligament

- prevents the femur sliding anteriorly on the tibia
- prevents the tibia sliding posteriorly on the femur

9

Primary function of the patella

- aids in knee extension by producing anterior displacement of the quadriceps tendon

10

The Q angle

- excessive lateral tracking of the patella
- angle is formed between the quadriceps line of force and line between patella and tibial tuberosity

11

Adductor longus

O - anterior surface of the body of the pubis

I - linea aspera of the femur

A - adducts the hip

12

Adductor brevis

O - anterior surface of the inferior pubic ramus

I - linea aspera of the femur

A - adducts the hip

13

Biceps femoris long head

O - posterior surface of the ischial tuberosity

I - head of the fibula

A - extends the hip and flexes the knee

14

Biceps femoris short head

O - lateral lip of linea aspera

I - head of the fibula

A - flexes the knee

15

Gluteus maximus

O - outer ilium, posterior gluteal line and posterior side of sacrum and coccyx

I - gluteal tuberosity and iliotibial band

A - extends and externally rotates the hip

16

Gluteus minimus

O - outer surface of the ilium

I - anterior lateral aspect of the greater trochanter of the femur

A - abducts the hip

17

Gracilis

O - anterior aspect of lower body of the pubis and inferior ramus of pubis

I - proximal medial surface of the tibia

A - adducts the hip

18

Psoas major

O - transverse process, lateral bodies of the last thoracic and all lumbar vertebrae

I - lesser trochanter of the femur

A - hip flexion

19

Iliacus

O - iliac fossa, inner lip of iliac crest and across the sacroiliac joint

I - lesser trochanter of the femur

A - hip flexion

20

Pectineus

O - pectinieal line on superior pubic ramus

I - pectineal line on the posterior surface of the femur

A - adducts the hip

21

Piriformis

O - anterior side of the sacrum

I - apex of the greater trochanter of the femur

A - externally rotates the hip

22

Rectus femoris

O - anterior, inferior iliac spine, superior rim of acetabulum and into the hip capsule

I - base of the patella and the tibial tuberosity

A - flexes the hip and extensor of the knee

23

Sartorius

O - anterior superior iliac spine

I - proximal medial surface of the tibia

A - flexes, externally rotates and abducts the hip

24

Semimembranosus

O - posterior surface of the ischial tuberosity

I - posterior aspect of the medial condyle of the tibia

A - extends the hip and flexes the knee

25

Semitendinosus

O - posterior surface of the ischial tuberosity

I - proximal medial surface of the tibia

A - extends the hip and flexes the knee

26

Tensor fasciae latae

O - outer surface of the iliac crest

I - iliotibial band of the fasciae lata

A - flexes and abducts the hip
