1
Q

What are the superficial abductors and extenders of the gluteal region?

A

gluteus minimus, gluteus medius and gluteus maximus. Also contains the tensor fasciae latae, which acts on the knee joint.

2
Q

What the deep lateral rotators of the gluteal region?

A

quadratus femoris, piriformis, gemellus superior, gemellus inferior and obturator internus

3
Q

What are the actions of the gluteus maximus?

A

It is the main extensor of the thigh, and assists with lateral rotation. Only used when force required.

4
Q

What is the innervation of the gluteus maximus?

A

Inferior gluteal nerve

5
Q

What is A?

A

A Gluteus maximus

6
Q

What is B?

A

Gluteus medius

7
Q

What is the action of the gluteus medius?

A

Abduction and medial rotation upon hip flexion. Also prevents pelvic drop.

8
Q

What is the innervation of the gluteus medius?

A

Superior gluteal nerve

9
Q

Where is gluteus minimus found?

A

Posterior to gluteus medius

10
Q

What is the action of gluteus minimus?

A

Abduction and medial rotation upon hip flexion (stronger than medius). Prevents pelvic drop.

11
Q

What is the innervaton of gluteus minimus?

A

Superior gluteal nerve

12
Q

What happens if superior gluteal nerve injured?

A

Gluteus minimus and medius paralysed, causing pelvic drop. Patient also walks with gluteal gait - the leg swings out laterally so that the foot can move forward, producing a shuffling or waddling gait.

13
Q

What is A?

A

B Inerior gluteal nerves

14
Q

What is B?

A

Superior gluteal nerves

15
Q

What is C?

A

Sciatic nerves

16
Q

What is D?

A

Piriformis

17
Q

What is the action of the piriformis?

A

Lateral rotation and abduction of leg at hip joint

18
Q

What is the innervation of piriformis?

A

Nerve to piriformis

19
Q

What is important about the piriformis?

A

Travels through great sciatic foramen and divids it into an inferior and superior part

20
Q

What are A, B and C?

A

SOI A - Superior gemellus B - Obturator internus C - Inferior Gemellus

21
Q

-What is the action of the oburator internus?

A

Along with gemelli and quadratus femoris pulls the head of the femur into the acetabulum, stabilising hip joint Lateral rotation and abduction

22
Q

What is the innervation of the obturator internus?

A

Nerve to obturator internus

23
Q

What are the gemelli superior and inferior seperated by?

A

Obturnator internus tendon

24
Q

What are the actions of the gemelli?

A

Lateral rotation and abduction

25
Q

What is the innervation of the superior gemellus muscle?

A

Innervated by the nerve to obturator internus

26
Q

What is the innervation to the inferior gemelus muscle?

A

Nerve to the quadratus femoris

27
Q

What is D?

A

Quadratus femoris

28
Q

What are the actions of the quadratus femoris?

A

Lateral rotation

29
Q

What is the innervation to quadratus femoris?

A

Nerve to quadratus femoris
