Muscles of the Hip and Knee

Question 1

Quadriceps femoris

Answer 1

1. Vastus Muscles

2. rectus Femoris

Question 2

Vastus Muscles

Answer 2

3 muscles that originate on the femur

1. Vastus medialis
2. Vastus Lateralis
3. Vastus Intermedialis

Question 3

Rectus Femoris

Answer 3

origin in the ilium

actions: extension of knee and flexion of hip joint
stretch: heel to seat with pelvis on floor

Question 4

Hamstrings

Answer 4

3 posterior thigh muscles which cross both hip and knee

1. Semimenbranous
2. Semitendinous
3. Biceps femoris

Action: extend the hip and flex the knee

Question 5

Semimembranous

Answer 5

origin at ishial tuberosity

attaches to inner back aspect of the tibial condyle

Question 6

Semitendinous

Answer 6

origin at ishial tuberosity

inserts via a long thin tendon to the super medial tibial shaft

Question 7

Biceps femoris

Answer 7

2 heads

long head - origin at ishial tuberosity
short head - origin at the posterior femoral shaft

insert at the head of fibula

Question 8

Gluteus medias

Answer 8

broad origin on the external iliac fossa

insert on the lateral aspects of the greater trochanter

action: hip abduction and assists with flexion and extension of hip

Question 9

Gluteus minimus

Answer 9

small muscle origin in front of flutes medias

inserts on front aspect of greater trochanter

action: hip abduction and assists with flexion and extension of hip

Question 10

Gluteus maximus

Answer 10

largest muscle in body

origin from posteriolateral sacrum, posterior ilium and sacrotuberous ligament, which connects lower sacrum with ischial tuberosity

action: hip extension, lateral rotation

Question 11

Tensor Fascia Latae

Answer 11

located pants front pocket

superficial portion of gluteus maximus

insert onto iliotibial tract from opposite directions

Question 12

IT-Band

Answer 12

woven into the femoral fascia

inserted in a protuberance laterally and below the knee

Question 13

Sartoris

Answer 13

longest muscle in body

origin from anterior superior iliac spine and runs down medially on the thigh over the quadriceps

insert on the superomedial shaft of the tibia

action: flexion of hip, lateral rotation, abduction of the hip

Question 14

Adductors

Answer 14

Pectineus 
Adductor brevis 
Adductor longus
Adductor magnus 
Gracillis

Question 15

Pectineus

Answer 15

origin at lateral pubis and lessor trochanter to run down the femur

attaches at linea aspera

Question 16

Adductor brevis

Answer 16

origin at medial pubis

attaches to middle part of line aspera

Question 17

Adductor longus

Answer 17

more medially on the pubis and runs anterior to the adductor brevis muscle

insert lower down on the line aspera

Question 18

Gracillis

Answer 18

long thin outer adductor

origin on the inferomedial pubis

insert onto the tibial shaft below medial condyle

Question 19

Adductor magnus

Answer 19

largest and strongest of adductors

origin form the ishio pubic rams and runs infereo medially

ending in a very broad insertion on the line aspera
