1

What movements can be carried out at the Hip Joint?

1. Flexion
2. Extension
3. Abduction
4. Adduction
5. Lateral Rotation
6. Medial Rotation
7. Circumduction

2

What are the main Flexors of the Hip Joint?

1. Iliopsoas Muscle
2. Rectus Femoris Muscle
3. Sartorius Muscle
4. Pectineus Muscle

3

How many muscles is the Iliopsoas Muscle?

2

4

What are the 2 Muscles which form the Iliopsoas Muscle?

1. Psoas Major Muscle
2. Iliacus Muscle

5

What happens to the Psoas Major and Iliacus Muscle?

They come together to form a tendon, hence why they are sometimes referred to as one muscle

6

Where does the Psoas Major Muscle originate from?

The Vertebral Bodies, and associated Interverterbral Disks of:
1. T12
2. L1
3. L2
4. L3

7

Where does the Iliacus Muscle originate from?

The Iliac Fossa of the Pelvis

8

Where do the Psoas Major and Iliacus Muscles merge, to form the Iliopsoas Muscle?

In the Thigh

9

Where does the Iliopsoas Muscle attach distally?

The Lesser Trochanter of the Femur

10

What is the function of the Iliopsoas Muscle?

1. Flexion of the Lower Limb at the Hip Joint
2. Assists in Lateral Rotation of the Lower Limb at the Hip Joint

11

What is the innervation of the Psoas Major Muscle?

Anterior Rami of L1-L3

12

What is the innervation of the Iliacus Muscle?

Femoral Nerve

13

Where does the Rectus Femoris Muscle originate from?

The Ilium, immediately superior to the Acetabulum

14

Where does the Rectus Femoris Muscle travel?

Straight down the Leg
Note - Latin for Straight is Rectus

15

Where does the Rectus Femoris Muscle attach distally?

The Patella, via the Quadriceps Tendon

16

What is the function of the Rectus Femoris Muscle?

1. Flexion of the Lower Limb at the Hip Joint
2. Extension of the Knee Joint

17

What is the innervation of the Rectus Femoris Muscle?

The Femoral Nerve

18

Where does the Sartorius Muscle originate from?

Anterior Superior Iliac Spine

19

Where does the Sartorius Muscle attach distally?

Superior, Medial surface of the Tibia

20

What is significant about the Sartorius Muscle?

It is the longest Muscle in the Body

21

Where does the Sartorius Muscle travel?

1. Across the Thigh, Inferomedially
2. More Superficially than other Muscles in the Leg

22

What is the function of the Sartorius Muscle?

1. Flexion of the Hip Joint
2. Abduction of the Hip Joint
3. Lateral Rotation of the Hip Joint
4. Flexion of the Knee Joint

23

What is the innervation of the Sartorius Muscle?

The Femoral Nerve

24

Where is the Pectineus Muscle located, and what does this form?

Base of the Femoral Triangle

25

Where does the Pectineus Muscle originate from?

Pectineal Line of the Anterior Surface of the Pelvis

26

Where does the Pectineus Muscle attach distally?

Pectineal Line of the Posterior Surface of the Femur, just inferior to the Lesser Trochanter

27

What is the function of the Pectineus Muscle?

1. Adduction of the Hip Joint
2. Flexion of the Hip Joint

28

What is significant about the innervation of the Pectineus Muscle?

It has dual innervation, so can be considered a transitional muscle between the Anterior and Medial Compartments of the Thigh

29

What is the innervation of the Pectineus Muscle?

1. Femoral Nerve
2. It may also receive a branch from the Obturator Nerve
