The Glueteal Region And Posterior Thigh

Front 1

what type of joint is the hip joint and what is the articulation?

Back 1

a synovial ball and socket joint between the acetabulum and the head of the femur

Front 2

what does the greater sciatic foramina do?

Back 2

conveys muscles nerves and vessels from the pelvis to the gluteal region

Front 3

ilifemoral ligament

Back 3

Y shaped hip ligament that is the strongest of the hip ligaments and resists excessive hyperextension of the hip; attaches proximally to the anterior inferior iliac spine and acetabular rim; attaches distally to the intertrochanteric line

Front 4

what are the hip flexor muscles?

Back 4

ilipsoas(strongest), tensor fascia lata; sartorius and pectineus also used during walking

Front 5

what are the hip extensor muscles?

Back 5

gluteus maximus and posterior part of the adductor magnus; hamstrings

Front 6

what are the hip abductors?

Back 6

gluteus medius and minimus (maintain a stable pelvis)

Front 7

what are the hip adductors?

Back 7

adductor magnus, brevis, longus; gracilis

Front 8

what are the medial rotators of the hip?

Back 8

anterior part of the gluteus minimus

Front 9

what are the lateral rotators of the hip?

Back 9

pyriformis, obturator internus and gemelli, obturator externus, quadratus femoris, gluteus maximus and posterior fibers of the gluteus medius

Front 10

what is the insertion of the gluteus maximus?

Back 10

iliotibial tract

Front 11

what is the insertion of the tensor fascia lata?

Back 11

iliotibial tract

Front 12

what muscles insert on the greater trochanter of the femur?

Back 12

gluteus medius, gluteus minimus, pyriformis, obturator internus,

Front 13

what two muscles insert on the obturator internus tendon?

Back 13

superior and inferior gemelli

Front 14

what is the action of the gluteus maximus?

Back 14

extension, lateral rotation and adduction of the hip

Front 15

what is the action of the gluteus medius?

Back 15

medial rotation and/or lateral rotation of hip; hip abduction and extension

Front 16

what is the action of the gluteus minimus?

Back 16

abduction, medial rotation, and flexion of the hip.

Front 17

what is the action of the tensor fascia lata?

Back 17

abduction, flexion and medial rotation of the hip; extension and lateral rotation of the knee

Front 18

what is the insertion of the biceps femoris

Back 18

head of the fibula

Front 19

what innervates the short head of the biceps femoris?

Back 19

common fibular sciatic nerve

Front 20

what all enters the gluteal region through the greater sciatic foramen below the pyriformis muscle?

Back 20

pudendal neurovascular bundle, inferior gluteal nerves and vessels, sciatic nerve, posterior cutaneous nerve of the thigh

Front 21

what is the blood supply of the posterior thigh?

Back 21

the perforating arteries coming off the deep artery of the thigh (profunda femoris)

Front 22

hyperextension of the knee breaks what ligament?

Back 22

ACL

Front 23

what is the cruciate anastomosis and what does it bypass?

Back 23

it can supply the leg if theres a partial occlusion of femoral artery by using anastomoses between inferior gluteal and circumflex femoral arteries and between circumflex femorals and perforating deep femoral branches.
