Gluteal Region And Sacral Plexus Flashcards
What are the three zones on outer surface of the ala of ilium?
posterior gluteal line
Anterior gluteal line
Inferior gluteal line
the medial lip of the linea aspera becomes the?
pectineal line
The lateral lip of the linea aspera become the?
gluteal Tuberosity
What serves as the lower border for the great sciatic foramen?
sacrospinous ligament
What forms the lesser sciatic foramen?
sacrotuberous ligament
What is the purpose of the sacroiliac joint?
reinforce the synovial joint between sacrum and ilium
Gluteus maximus origin
wing of ilium posterior to the posterior gluteal line, dorsal surface of sacrum, and sacrotuberous ligament
gluteus maximus insertion
upper fibers insert on the iliotibial tract, fascia latae; lower fibers attach to gluteal Tuberosity of femur
gluteus maximus action
major hip extensor, lateral rotation of thigh, some abduction
gluteus maximus nerve
inferior gluteal nerve
gluteus maximus blood supply
superior and inferior gluteal artery
gluteus medius origin
wing of ilium between posterior and anterior gluteal linea
gluteus medius insertion
posterior and lateral aspect of greater troachanter of femur
gluteus medius action
strong abduction
medial rotation
steadies pelvis on leg when opposed leg is raise.
if the gluteus medius is weak, what gait could it result in?
Trendelenburg
gluteus medius nerve
superior gluteal nerve
gluteus medius blood
superior gluteal artery
gluteus minimus origin
wing of ilium between anterior and inferior gluteal lines
gluteus minimus insertion
anterior and medial aspect of greater troachanter
gluteus minimus action
abduction and medial rotation of femur at hip; same function as gluteus medius (steadies pelvis)
gluteus minimus nerve
superior gluteal nerve (L5&S1)
gluteus minimus blood
superior gluteal artery
Tensor fascia latae origin
anterior part of iliac crest, right next to asis
tensor fascia latae insertion
iliotibial band (which inserts on lateral condyle of tibia
tensor fascia latae action
flexion of hip, see abduction and medial rotation
tensor fascia latae nerve
superior gluteal nerve
tensor fascia latae blood
superior gluteal artery
The ____ is the deep portion of fascia (deep fascia of thigh that surrounds all thigh muscles)
fascia latae
The stout _____ portion of the fascia latae forms the IT band or iliotibial tract
lateral
Piriformis(triangle shape)origin
pelvic surface of of anterior sacrum between 1st-4th sacral foramina and sacrotuberous ligament
piriformis insertion
superior portion of greater trochanter
piriformis action
abduction and lateral rotator at hip
piriformis nerve
nerve to piriformis (VPR of S1&S2)
piriformis blood
inferior gluteal artery
The greater sciatic nerve passes through the greater sciatic foramen ____ to piriformis
inferior
superior gemellus origin
dorsal surface of ischial spine
superior gemellus insertion
along with tendon of obturator intermuscular into upper border of greater trochanter
superior gemellus action
lateral rotation of thigh at hip
superior gemellus nerve
nerve to obturator internus
superior gemellus blood
inferior gluteal artery
the gemellus muscles are pre axial or post axial?
preaxial
inferior gemellus origin
upper margin ischial Tuberosity
inferior gemellus insertion
with tendon of obturator internus to upper border of greater trochanter
inferior gemellus action
lateral rotation of thigh at hip
inferior gemellus nerve
nerve to quadratus femoris
inferior gemellus blood
inferior gluteal artery
muscle arising from ischium or pubis are ____ while those arising from ilium sacrum of pubis are___
pre axial
post axial
