Untitled Deck Flashcards
Glute Max Origin
Ilium post to posterior gluteal line, dorsal surface of sacrum and coccyx, sacrotuberous ligament.
Glute Max Insertion
Most fibers end in iliotibial tracts, which insert to lateral condyle of tibia. Some fibers insert on gluteal tuberosity.
Glute Max Innervation
Inferior gluteal nerve (L5, S1, S2).
Glute Max Action
Extends joint (especially when flexed), assists in lateral rotation, fixed hip, and assists in rising from sitting.
Glute Med Origin
External surface of ilium between anterior and posterior gluteal line.
Glute Med Insertion
Lateral greater trochanter.
Glute Med Innervation
Superior gluteal nerve (L5, S1).
Glute Med Action
Abducts and medially rotates hip, keeps pelvis level when ipsilateral side is weight bearing and when contralateral side is during swing phase.
Glute Min Origin
External surface of ilium between anterior and inferior gluteal line.
Glute Min Insertion
Anterior greater trochanter.
Glute Min Innervation
Superior gluteal nerve (L5, S1).
Glute Min Action
Abducts and medially rotates hip, keeps pelvis level when ipsilateral side is weight bearing when contralateral side is unsupported during swing phase.
TFL Origin
Anterior superior iliac spine, anterior iliac crest.
TFL Insertion
Iliotibial tract, lateral epicondyle of tibia.
TFL Innervation
Superior gluteal nerve (L5, S1).
TFL Action
Abducts and medially rotates hip, keeps pelvis level when ipsilateral side is weight bearing, and when contralateral side is during swing phase.
Piriformis Origin
Anterior surface of sacrum, sacrotuberous ligament.
Piriformis Insertion
Superior border of greater trochanter.
Piriformis Innervation
Anterior rami (L5, S1).
Piriformis Action
Laterally rotates when extended, abducts when flexed, stabilizes hip joint.
Obturator Internus Origin
Pelvic surface of obturator membrane and surrounding bones.
Obturator Internus Insertion
Medial surface of greater trochanter, trochanteric fossa.
Obturator Internus Innervation
Obturator internus nerve (L5, S1).
Obturator Internus Action
Laterally rotates when extended, abducts when flexed, stabilizes hip joint.
Superior Gemellus Origin
Ischial spine.
Inferior Gemellus Origin
Ischial tuberosity.
Gemelli Insertion
Medial surface of greater trochanter, trochanteric fossa.
Gemelli Innervation
Superior: Obturator internus nerve (L5, S1), Inferior: Quadratus femoris nerve (L5, S1).
Gemelli Action
Laterally rotates when extended, abducts when flexed, stabilizes hip joint.
Quadratus Femoris Origin
Lateral border of ischial tuberosity.
Quadratus Femoris Insertion
Quadrate tubercle on intertrochanteric crest and area inferior to it.
Quadratus Femoris Innervation
Quadratus femoris nerve (L5, S1).
Quadratus Femoris Action
Laterally rotates, stabilizes hip.
