Butt Flashcards
gluteus maximus AIM
A: pelvis (several regions) to gluteal tuberosity (femur)
I: inferior gluteal n.
M: hip extension and ER/LR
Gluteus Medius AIM
A: pelvis to greater trochanter
I: superior gluteal n.
M: hip abduction
Gluteus minimus AIM
A: pelvis to greater trochanter
I: superior gluteal n.
M: hip abduction
tensor of fascia lata AIM
A: pelvis to ITB
I: superior gluteal n.
M: hip abduction
Only muscles innervated by superior gluteal nerve
Gluteus medius, minimus and tensor of fascia lata
Other muscles in butt and their AM
Piriformis Superior gemellus Obturator internus Inferior gemmellus Quadratus femoris A: pelvis to femur M: hip ER/LR for all muscles
Piriformis
passes through greater sciatic foramen
Superior and inferior gemellus
blend to form common tendon with obturator
Quadratus femoris
inside pelvis to femur
Inferior gluteal nerve
motor to gluteus maximus
Pathway of inferior gluteal nerve
Leaves pelvis and passes lots of motor branches
Superior gluteal nerve
motor to gluteus medius, gluteus minimus, and tensor fasciae latae
Pathway of superior gluteal nerve
o Between minimus and medius then fibers pass anteriorly to reach tensor fasciae latae
Pathway of sciatic nerve
passes through gluteal region
Does sciatic nerve innervate muscles in gluteal region?
NO
