8 - Gluteal Region Flashcards
What are the superficial abductors and extenders of the gluteal region?
gluteus minimus, gluteus medius and gluteus maximus. Also contains the tensor fasciae latae, which acts on the knee joint.
What the deep lateral rotators of the gluteal region?
quadratus femoris, piriformis, gemellus superior, gemellus inferior and obturator internus
What are the actions of the gluteus maximus?
It is the main extensor of the thigh, and assists with lateral rotation. Only used when force required.
What is the innervation of the gluteus maximus?
Inferior gluteal nerve
What is A?
A Gluteus maximus
What is B?
Gluteus medius
What is the action of the gluteus medius?
Abduction and medial rotation upon hip flexion. Also prevents pelvic drop.
What is the innervation of the gluteus medius?
Superior gluteal nerve
Where is gluteus minimus found?
Posterior to gluteus medius
What is the action of gluteus minimus?
Abduction and medial rotation upon hip flexion (stronger than medius). Prevents pelvic drop.
What is the innervaton of gluteus minimus?
Superior gluteal nerve
What happens if superior gluteal nerve injured?
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.
What is A?
B Inerior gluteal nerves
What is B?
Superior gluteal nerves
What is C?
Sciatic nerves
