Gluteus Muscles Flashcards
What nerve innovated the gluteus maximum
Inferior gluteal nerve
What is the function of the gluteus maximus muscle
Lateral rotation
ABduction
Extends the thigh at the hip
What nerve innovates the gluteus medius and minimus
The superior gluteal nerve
What is the function of the gluteus medius and minimus
Medial rotation
Abduction
What nerve innovates the piriformis
Bracnches of the anterior rami
L5 to S2
What does the pirifomis do
Lateral rotation of extended thigh at the knee
Abducts flexed hip
What nerve innovates the obturator internus
The nerve to the obturator internus
L5 to S2
What does the obturator internus do
Lateral rotation of extended thigh at knee
Abducts a flexes thigh at the hip
What nerve goes to the superior and inferior gemelli
Superior gemelli nerve
Same nerve that would go to the obturator internus
What does the gemelli do
Lateral rotation of the thigh when extended
Abduction of a flexed thigh at hip
What is the nerve to the quadratic femoris
Nerve to the quadratus femoris
L4 to S1
What does the quadratus femoris do
Laterally rotates the thigh at hip
What is the first area that is safe for gluteal injections
Vertical line - down from the highest point of the iliac crest
Horizontal line - mid way between the iliac crest and the ishical tuberosity
Safe area would be the top LEFT corner
What is the second area that is safe
Vertical line - down from the highest point of the iliac crest
Diagonal line - from the PSIS to the greater tuberosity of the femur
Safe is the top RIGHT corner
Where do the nerves in the gluteal region comes from
The sacral plexus
