Practice Quiz
1. How many de- 3:
grees of freedom 1. Flexion/ Extension
are there in the 2. Internal/ External rotation
hip? 3. Proximal/ Distal
2. What kind of joint Ball and socket=> formed where the femur meets the three bones that make up
is the hip joint? the hip: illium, ischium, pubis
3. Describe the Ar- A layer of soft tissue that covers the femoral head and the acetabulum=> white,
ticular cartilage shiny, rubbery consistency and is kept slippery by a fluid made in the synovial
in the hip joint membrane
4. acetabulum sur- illium, ischium, and pubis were all seperate bones during childhood and then fuse
rounding bones together during puberty
5. pelvic anatomy: -Articular capsule: made of pubofemoral, ischiofemoral, illiofemoral that make the
acetabulum envelope of tissue surrounding the hip joint acting as a tether to keep the femoral
head and acetabulum stable and connected
-Acetabular labrum: fibrous rim of articular cartilage surrounding the acetabulum
to help deepen the socket for the femoral head to sit into the socket
6. what is important The surgeon is using it as a landmark to be able to locate the acetabulum and the
about the ASIS proximity to where the femoral head will be located
for the surgeon
to be able to pal-
pate and locate
it?
7. ligamentum fovea capitis on femur and the fossa of the acetabulum
teres bony
landmarks
8. hip abductors glut medius, glut minimus, TFL
1/7
, 9. hip adductors pectineus, adductor brevis, adductor longus, adductor magnus
10. Hip Extensors glut maximus, hamstrings
11. how many mus- 4 but there are 5 total adductors with the pectineus
cles have the
name "adductor"
in it?
12. Hip Flexors illiacus, psoas major, rectus femoris, sartorius
13. Hip external rota- piriformis, superior gemellus, obturator internus, inferior gemellus, quadratus
tors femoris
14. major ateries to femoral artery and the circumflex arteries provides to the femoral head
the thigh
15. sciatic nerve starts through the sciatic notch and flows down to the lower leg to innervate the
hamstrings
16. what makes up both left and right hip joints=> sacrum, left and right acetabulum, left and right
the pelvic girdle? pubis, ischium, illium
17. 3 ligaments that pubofemoral, ischiofemoral, illiofemoral
tether the proxi-
mal femur?
18. what is the main medial and lateral circumflex arteries
supply of blood
to the femoral
head as we are
adults?
19. femoral nerve
