Question 1

Answer 1

Gluteus Maximus

Question 2

Answer 2

Gluteus Medius

Question 3

Answer 3

Gluteus Minimus

Question 4

Answer 4

Piriformis

(note Sciatic Nerve exiting below)

Question 5

Answer 5

Obturator Internus

(thin, white, in between superior and inferior gemelli)

Question 6

Answer 6

Superior and Inferior Gemelli

Question 7

Answer 7

Quadratus Femoris

(most inferior of rotators. Larger, square-like.)

Question 8

Answer 8

Sciatic Nerve

(Exits below piriformis. Continues as Sciatic Nerve until branching to Common Fibular and Tibial nerves.)

Question 9

Answer 9

Sacrotuberous Ligament

(sacrum to ischial tuberosity)

Question 10

Answer 10

Semimembranosus

(Medial and a bit deep to semitendinosus. Not as long, shorter tendon, typically fatter.)

Question 11

Answer 11

Semitendinosus

(Longer, with longer tendon. Less medial than membranosus.)

Question 12

Answer 12

Biceps Femoris, Long Head

(origin at ischial tuberosity, crosses back of leg.)

Question 13

Answer 13

Biceps Femoris, Short Head

(mostly deep to the long head, except at the knee where they lie lateral to the long head.)

Question 14

Answer 14

Sciatic Nerve Tibial Branch

(More medial, the tibial side.)

Question 15

Answer 15

Sciatic Nerve Common Fibular Branch

(more lateral, the fibular side.)

Question 16

Answer 16

Popliteal Artery and Vein

(right behind knee.)

Question 17

Answer 17

Satorius

(Long, only one that crosses anterior thigh.)

Question 18

Answer 18

Iliopsoas

(Becomes the iliopsoas once it crosses the inguinal ligament. In the femoral triangle, just medial to sartorius.)

Question 19

Answer 19

Rectus Femoris

(straight up and down.)

Question 20

Answer 20

Vastus Medialis

Question 21

Answer 21

Vastus Lateralis

Question 22

Answer 22

Vastus Intermedius

(deep to Rectus Femoris.)

Question 23

Answer 23

Tensor Fascia Lata

(most lateral in superior thigh, lateral to sartorius, inserts in to IT band.)

Question 24

Answer 24

Femoral Triangle

Boundaries: Sartorius, Inguinal Ligament, Adductor Longus.

Question 25

Answer 25

Femoral Triangle Contents

Lateral to Medial: Femoral Nerve, Artery, Vein

Lateral Muscle in Triangle is Iliopsoas.

Great Saphenous Vein splits medially from femoral vein (not shown.)

Question 26

Answer 26

Pectineus

(diagnoal from pubis into thigh, most superior of adductors)

superior P A G inferior

Question 27

Answer 27

Adductor Longus

(Most superficial of longus, brevis, magnus. Just lateral to gracilis.)

Question 28

Answer 28

Adductor Brevis

(In window between adductor longus and pectineus. Notice how it is being pulled out of window in picture.)

Question 29

Answer 29

Adductor Magnus

(Deep to the gracilis and adductor longus. Big, deep and has distinct white tendon. Has a hiatus: femoral artery and vein pass through and exit as the popliteal artery and vein at the knee.)

Question 30

Answer 30

Gracilis

(Most superficial of medial thigh. Long, runs along medial surface.)
