25
Where does the publfemoral ligament attach
Obturator crest of pubic bone to blending with capsule and illiofemoral ligament
26
What is the pubofemoral ligament check Rein

27
Where does the ischiocfemoral ligament attach
From the ischial part of the acetabular rim to the neck of the femur, medial to the greater trochanter
28
What does the ischiofemoral ligament check
Hyperextension
29
Is there a capsular attachment to the posterior aspect of the femur
No
30
What is the main blood supply to the hip
Medial circumflex femoral artery
31
Where does the medial femoral circus,flex artery arise from
The deep femoral artery near the next of the femur
32
Where does the artery of the femoral head travel through
The ligament to the head of the femur
33
If a femoral neck is fractured and does not allow the medial circumflex artery to fully supply the area what artery takes over
The Obturator artery
34
What is the superficial layer of gluteal muscles
Gluteus Maximus Gluteus medius Gluteus minimum Tensor of fascia lata
35
What is the deep layer of gluteal muscles
Piriformis Obturator internus Superior gemellus Inferior gemellus Quadratus femoris
36
The superficial gluteal muscles all share a common proximal attachment and action, what is it
Prox: ala and crest of ilium They extend, abduct, and Medially rotate the thigh
37
What is the largest nerve in the body
Sciatic nerve
38
When does the sciatic nerve have target points
Once it gets to the thigh
39
What does the clunial nerve supply
Skin of the buttocks The superior and middle clunial nn are posterior rami coming from upper lumbar and sacral levels
40
What nerves pass through the greater sciatic foramen
Superior gluteal Inferior gluteal Sciatic N to Quadratus femoral N to Obturator internus Posterior cutaneous n of thigh Pudendal n
41
All except what nerve emerges inferior to piriformis muscle
Superior gluteal nerve
42

Gluteus medius Gluteus minimus Tensor of fascia lata
43
What does inferior gluteal nerve innervates
Gluteus Maximus
44
What does nerve to quadratus femoris innervate
Inferior gemellus Quadratus femoris
45
What does posterior cutaneous nerve of the thigh innervates
Large area of skin including inferior half of buttock, posterior thigh, and popliteal fossa, lateral perineum and upper medial thigh
46
What gives off inferior clunial n
Posterior cutaneous nerve of the thigh
47
What does pudendal nerve innervate
It is most medial and dives into pelvis through lesser sciatic foramen. No function in gluteal region or posterior thigh
48
What ligament does the pudendal nerve wrap around
Sacrospinous ligament
49
What does nerve to Obturator internus innervate
Superior gemellus Obturator internus
50
What nerve is affected during a positive trendelenburg gait
Superior gluteal nerve
51
What are intragluteal injections
Injections into gluteal muscles bc they have great bulk for absorption of medication
52
What arteries are branches of internal iliac artery
Superior gluteal Inferior gluteal Internal pudendal
53
What artery remains anterior and passes through the femoral canal ti supply lower extremity structures
External iliac arteries
54
Where does the superior gluteal artery emerge through
The greater sciatic foramen superior to piriformis to supply the gluteal muscles
55
Where does the superior gluteal artery have anastomosis
To the medial circumflex femoral arteries
56
Where does the inferior gluteal artery emerge from
The greater sciatic foramen inferior to piriformis m. Along with the superior parts of the hamstrings
57
Where does the inferior gluteal artery for, anastomoses
Around the hip with the circumflex femoral arteries
58
Where does the internal pudendal artery emerge from
That along with pudendal nerve come out the greater sciatic foramen and back into the pelvis through the lesser sciatic foramen
59
What does the Internal pudendal artery supply
Perineal skin, external genitalia and perineal muscles
60
Where do the branches of the deep artery of the thigh penetrate
Aponeurosis aspect of the adductor magnus muscle
61
What is the main blood supply of the thigh
Medial circumflex artery
62
What are the hamstring muscles

68
What are the two nerves sciatic nerve is comprise of
Tibial nerve Common Fibular nerve
69
Where does the sciatic nerve emerge from
Pelvis, inferior to the piriformis through the greater sciatic foramen,
70
What is the usual location for when the sciatic nerve splits into tibial and common Fibular
