Question 1

Glute Max Origin

Answer 1

Ilium post to posterior gluteal line, dorsal surface of sacrum and coccyx, sacrotuberous ligament.

Question 2

Glute Max Insertion

Answer 2

Most fibers end in iliotibial tracts, which insert to lateral condyle of tibia. Some fibers insert on gluteal tuberosity.

Question 3

Glute Max Innervation

Answer 3

Inferior gluteal nerve (L5, S1, S2).

Question 4

Glute Max Action

Answer 4

Extends joint (especially when flexed), assists in lateral rotation, fixed hip, and assists in rising from sitting.

Question 5

Glute Med Origin

Answer 5

External surface of ilium between anterior and posterior gluteal line.

Question 6

Glute Med Insertion

Answer 6

Lateral greater trochanter.

Question 7

Glute Med Innervation

Answer 7

Superior gluteal nerve (L5, S1).

Question 8

Glute Med Action

Answer 8

Abducts and medially rotates hip, keeps pelvis level when ipsilateral side is weight bearing and when contralateral side is during swing phase.

Question 9

Glute Min Origin

Answer 9

External surface of ilium between anterior and inferior gluteal line.

Question 10

Glute Min Insertion

Answer 10

Anterior greater trochanter.

Question 11

Glute Min Innervation

Answer 11

Superior gluteal nerve (L5, S1).

Question 12

Glute Min Action

Answer 12

Abducts and medially rotates hip, keeps pelvis level when ipsilateral side is weight bearing when contralateral side is unsupported during swing phase.

Question 13

TFL Origin

Answer 13

Anterior superior iliac spine, anterior iliac crest.

Question 14

TFL Insertion

Answer 14

Iliotibial tract, lateral epicondyle of tibia.

Question 15

TFL Innervation

Answer 15

Superior gluteal nerve (L5, S1).

Question 16

TFL Action

Answer 16

Abducts and medially rotates hip, keeps pelvis level when ipsilateral side is weight bearing, and when contralateral side is during swing phase.
