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

2

What are the main Muscles of Medial Rotation of the Hip Joint?

1. Gluteus Medius Muscle
2. Gluteus Minimus Muscle
3. Semitendinosus Muscle
4. Semimembranosus Muscle

3

Where is the Gluteus Medius Muscle located?

In between the Gluteus Maximus and the Gluteus Minimus Muscles

4

How is the Gluteus Medius Muscle described?

Fan-Shaped, similar to the Gluteus Minimus Muscle

5

Where does the Gluteus Medius Muscle originate from?

Gluteal Surface of the Ilium

6

Where does the Gluteus Medius Muscle attach distally?

Lateral Surface of the Greater Trochanter of the Femur

7

What is the function of the Gluteus Medius Muscle?

1. Abduction of the Lower Limb at the Hip Joint
2. Medial Rotation of the Lower Limb at the Hip Joint
3. During Locomotion, it secures the Pelvis, preventing Pelvic Drop of the opposite Limb
4. The Posterior Fibers are thought to produce a small amount of Lateral Rotation of the Lower Limb at the Hip Joint

8

What is the innervation of the Gluteus Medius Muscle?

The Superior Gluteal Nerve

9

Where is the Gluteus Minimus Muscle located, in relation to the other Gluteal Muscles?

1. It is the Deepest and Smallest of the Superficial Gluteal Muscles (Gluteus Maximus and Medius Muscles)
2. It is Superficial to the Deep Gluteal Muscles (Piriformis, Gemelli)

10

What is the Gluteus Minimus Muscle's shape and function similar to?

Gluteus Medius Muscle, it is also Fan-Shaped

11

Where does the Gluteus Minimus Muscle originate from?

Ilium

12

Where does the Gluteus Minimus Muscle attach distally?

It converges to form a Tendon, inserting into the Anterior Side of the Greater Trochanter

13

What is the function of the Gluteus Minimus Muscle?

1. Abduction of the Lower Limb at the Hip Joint
2. Medial Rotation of the Lower Limb at the Hip Joint
3. During Locomotion, it secures the Pelvis, preventing Pelvic Drop of the opposite Limb

14

What is the innervation of the Gluteus Minimus Muscle?

Superior Gluteal Nerve

15

What is located underneath the Gluteus Minimus Muscle?

Deep Gluteal Muscles (Superior to Inferior):
1. Piriformis
2. Obturator Internus
3. Superior and Inferior Gemelli Muscles
4. Quadratus Femoris

16

How is the Semitendinosus Muscle described?

It is a largely Tendinous Muscle

17

Where is the Semitendinosus Muscle located, in relation to the Biceps Femoris?

Medially

18

What does the Semitendinosus Muscle cover?

The majority of the Semimembranosus Muscle

19

Where does the Semitendinosus Muscle originate from?

Ischial Tuberosity of the Pelvis

20

Where does the Semitendinosus Muscle attach distally?

Medial Surface of the Tibia

21

What is the function of the Semitendinosus Muscle?

1. Flexion of the Leg at the Knee Joint
2. Extension of the Thigh at the Hip Joint
3. Medially Rotation of the Thigh at the Hip Joint
4. Medially Rotation of the Leg at the Knee Joint

22

What is the innervation of the Semitendinosus Muscle?

Tibial Part of the Sciatic Nerve

23

Where is the Semimembranosus Muscle located, in relation to the Semitendinosus Muscle?

Deep

24

Where does the Semimembranosus Muscle originate from?

Ischial Tuberosity of the Pelvis, but more Superiorly than the Semitendinosus and Biceps Femoris Muscles

25

Where does the Semimembranosus Muscle attach distally?

Medial Tibial Condyle

26

What is the function of the Semimembranosus Muscle?
