Hip muscles

Question 1

The iliopsoas is made up of 2 muscles

Answer 1

Psoas major and iliacus

Question 2

Illiacus origin

Answer 2

Iliac fossa

Question 3

Psoas major origin

Answer 3

Transverse processes bodies, and intervertebral discs of the 5 lumbar vertebrae, intervertebral disc and body of the 12th thoracic vertebrae

Question 4

Iliopsoas insertion

Answer 4

The bundles of the muscles join distally and then form the iliopsoas tendon that
inserts on the lesser trochanter of the femur

Question 5

Primary concentric actions of the iliopsoas

Answer 5

Hip flexion

Question 6

Sartorius origin and insertion

Answer 6

O = Anterior superior iliac spine (ASIS) of the ilium
I = Proximal medial tibia at pes anserinus tendon

Question 7

Concentric actions of the sartorius

Answer 7

• Hip flexion
• Hip abduction
• Hip external rotation
• Knee flexion

Question 8

Rectus femoris O and I

Answer 8

O = ASIS
I = Tibial tuberosity on the tibia

Question 9

Concentric actions of the rectus femoris

Answer 9

Hip flexion
Knee extension

Question 10

Tensor Fascia Latae O and I

Answer 10

O = Iliac crest, posterior to the ASIS
I = Blends with tendon insertions from the gluteus maximus to form the iliotibial tract
(IT band) that inserts onto Gerdy’s tubercle on the lateral tibial condyle

Question 11

Answer 15

Extension / flexion

Question 16

Biceps femoris O and I

Answer 16

O = long head = Ischial tuberosity
Short head = Lateral lip of linea aspera of the femur
