Gluteal Region Flashcards
Gluteal maximus attachments
dorsal surface of sacrum, gluteal surface of ilium, thracombular fascia, and sacrotuberous ligament
superior-iliotibial tract
inferior-gluteal tuberosity
Gluteal maximus innervation
inferior gluteal nerve
l5-s2
Gluteal maximus actions
extend and externally rotate the femur at hip joint in sagittal and coronal planes
superior-abduct femus at hip joint
inferior-adduct femur at hip joint
gluteal medius attachments
gluteal surface of iium below iliac crest between anterior and posterior gluteal line
lateral surface of greater trochatnter of femur
gluteal medius innervation
gluteal nerve l4-s1
gluteal medius actions
abducts femur at hip joint and stabilizes pelvis coronally
anerior-flex and internally rotate femur at hip joint
posterior extent and externally rotate femur at hip joint`
piriformis attachments what it looks like
originates from pelvic surface of sacrum
inserts into apex of greater trochanter of femur
pear shaped
piriformis innervation
sacral pleux s1/s2
piriformis actions
externally, rotate, abduct, and extend femur at hip joint
act to stabilize the hip joint
where does…
superior gluteal vessels and nerve
inferior gluteal vessels and nerve
large sciatic nerve
posterior femoral cutaneous nerve+where compared to sciatic nerve
emerge from pelvis superior to piriformis
emerges from pelvis inferior to the piriformis x3
medial to sciatic nerve
Obturator internus attachments
inner surface of obturator membrane
medial surface of greater trochanter of femur
Obturator internus innervation
sacral plexus l5-s1
Obturator internus actions
externally rotate and extend femur at hip joint
abdects or adducts femur at hip joint depending on position of joint
gemellus superior attachments
ischial spine
medial surface of greater trochanter of femur
gemellus superior innervation
sacral plexus l5, s1
gemellus superior actions
externaly rotate and extend femur at hip joint
abduct or adduct femur at hip joint depending on position of joint
gemellus inferior attachents
ischial tuberoisty
medial surface of greater trochatnter of femur
gemellus inferior innervations
sacral plexus l5, s1
gemellus inferior actions
externally rotate and extend femur at hip joint
also abducts or adducts femur at hip depending on position of joint
quadratus femoris attachments
lateral border of ischial tuberosity
intertrochanteric crest of femur
quadratus femoris innervation
sacral plexus l5-d1
quadratus femoris actions
externally rotate and extend femur at hip joint
order of hip to leg muscles from superior to inferior
and big three that rally connect
piriformis
gemellus superior and inferior
quadratus femoris
gluteus medus-superior
gluteus minimus-more inferior
gluteus maximus-inferior and to sacrum
where is sacratuberous ligaments
-what connect to
-superficial to what
connected tobase of spine
ONLY TENDON ATTACHING to SPINE FOR LEG
superfical to gemellus superior
where is sacrospnasous ligament
-deep to what
sacratuberous ligament
internal pudendal vessels and pudendal nerve
between sacrotuberous and sacrospinous
cross under sacrospinous ligament (picture says under) text says over
gluteus minimus
where is it/attachments
under gluteus medius
gluteal surface of ilium just below origin of gluteus medius
inserts onto anterolateral surface of greater trocahter of femur
gluteus minumus innervation
superior gluteal nerve
l4-s1
gluteus minumus actions
all-abduct femur at hip joint and stabilize pelvis in coronal plane
anterior-flex and internally rotate femur at hip joint
posterior-extend and externaly rotate femur at hip joint
