The insides of the foramen (nose to eyes section)

Question 8

What ring of fibrocartilage supports the coxofemoral joint?

Answer 9

Articular Cartilage

Question 10

What plane-joint movements is the hip capable of?

Answer 10

Flexion, Extension, Adduction, Abduction, Internal & External Rotation

Question 11

What is lumbo-pelvic rhythm?

Answer 11

The interconnection of the lumbar spine, the sacrum, the pelvis and the hip joint

Question 12

Anterior pelvic tilt rotates the pelvis _______

Answer 12

Forward

Question 13

Posterior pelvic tilt rotate the pelvis ______

Answer 13

Backward

Question 14

What is lateral pelvic tilt?

Answer 14

When one coxofemoral joint moves superiorly or inferiorly to the other

Question 15

When can an athlete demonstrate an inferior lateral pelvic tilt?

Answer 15

Weak gluteus medius and minimus

Question 16

How does an inferior lateral pelvic tilt show in an athlete?

Answer 16

non-weightbearing side dropping during single-limb stance

Question 17

What is pelvic rotation?

Answer 17

When one side of the pelvis rotates around a fixed femur on the opposite side

Question 18

What part of the hip is most often associated with hip flexion?

Answer 18

Iliopsoas (the hip flexor)

Question 19

What 2 muscles make up the iliopsoas?

Answer 19

The iliacus and the psoas major

Question 20

Where does the iliacus originate?

Answer 20

The pelvis

Question 21

Where does the psoas major originate?

Answer 21

The lumbar spine

Question 22

Where do the iliacus and psoas major insert?

Answer 22

The proximal end of the femur

Question 23

Which muscle crosses the hip and assists in hip flexion?

Answer 23

Rectus femoris

Question 24

Where is the sartorius?

Answer 24

Originates at the anterior hip (anterior superior iliac spine)and crosses over the anterior aspect of the thigh to inserts onto the medial aspect of the tibia

Question 25

What does the sartorius muscle do?

Answer 25

Assist with hip flexion

Question 26

What is the purpose of the tensor fasciae latae?

Answer 26

Contributes to hip flexion and modulation tension on the iliotibial band (ITB)

Question 27

Where is the tensor fascia latae?

Answer 27

Upper outside of the leg, lateral to the superior portion of the sartorius. Originates on the iliac crest, inserts into the lateral aspect on the tibia via the ITB

Question 28

What are the primary extensors of the hip?

Answer 28

Gluteus maximus & hamstrings

Question 29

What are the 3 muscles of the hamstring?

Answer 29

Semitendinosus, Semimembranosus, Biceps Femoris

Question 30

What other muscles also help with extension of the hip?

Answer 30

Gluteus medius, adductor magnus, piriformis

Question 31

What do the gluteus medius and minimus assist in?

Answer 31

Hip Abduction

Question 32

Why are these muscles relative to athletic capability?

Answer 32

Weak abductors can be related to knee injuries such as ACL ears due to valgus knees from poor abduction.

Question 33

What chronic conditions may arise from weak abductors?

Answer 33

Patellofemoral pain syndrome, patellar tendonitis, and ITB Syndrome.

Question 34

What 5 muscles function as adductors?

Answer 34

Adductor Magnus, Adductor Brevis, Adductor Longus, Pectineus, Gracilis

Question 35

What muscle is primarily implicated in hip pain / sciatica?

Answer 35

Piriformis

Question 36

How does the piriformis affect Sciatica?

Answer 36

The sciatic nerve runs inferior to the piriformis. Tightness of the piriformis can compress the nerve resulting in pain in the nerve’s distribution

Question 37

The prevailing theory is that the adductors primarily contribute to ________

Answer 37

Stabilisation of the hip during single leg activities (walking, running)
