Gluteal Region Flashcards
What three bones make up the hip bone?
- Ilium
- Pubis
- Ischium
What is the name of the ridge of bone that runs along the medial surface of the ilium towards the pubis?
Arcuate line
What structure separates the greater and lesser sciatic notches?
Ischial spine
What is the name of the deep socket for the hip joint?
Acetabulum
What is the angle of inclination?
An angle resulting from the intersection of a line down the long shaft of the femur and a line drawn through the neck of the femur
What is a normal angle of inclination?
120 degrees
Which end of the femur is more medial?
The distal end
What is the angle of torsion?
The angle between the axis of the femoral head and neck and the transverse axis of the femoral condyles
What muscles in the gluteal region are lateral rotators of the hip?
- Gluteus maximus
- Piriformus
- Obturator internus
- Gemelli
- Quadratis femoris
What muscles in the gluteal region are medial rotators and abductors of the hip?
- Gluteus medius
- Gluteus minimus
What is the main role of the tensor fasciae latae?
To support the hip
What ensures the toes remain pointing forwards and the feet stay parallel during walking?
The limb rotating in an opposite direction to the movement of the pelvis
What nerve passes through the gluteal region but doesn’t innervate it?
Sciatic nerve
What are the two branches of the sciatic nerve?
- Tibial nerve
- Common peroneal nerve
What nerve emerges inferior to the piriformis muscle?
Tibial nerve
What nerve can emerge below, above or through the piriformis muscle?
Common perineal nerve
The gluteal nerves and vessels are named as superior or inferior in relation to which muscle?
Piriformis
What nerve supplies the skin covering the posterior tigh?
Posterior cutaneous nerve of the thigh
What nerve supplies the inferior part of the skin covering the buttocks?
Inferior clunial nerve
What are the proximal and distal attachments of the iliofemoral ligament?
Proximal - the anterior inferior iliac spine
Distal - the intertrochanteric line
What does the iliofemoral ligament limit in the leg?
Extension, lateral rotation, adduction and abduction
What are the proximal and distal attachments of the pubofemoral ligament?
Proximal - iliopubic eminence
Distal - lower part of the intertrochanter line
What does the pubofemoral ligament limit in the leg?
Extension, lateral rotation and abduction
What are the proximal and distal attachments of the ishiofemoral ligament?
Proximal - the posterior aspect of the acetabulum
Distal - The greater trochanter
What does the ishiofemoral ligament limit in the leg?
Extension, medial rotation, adduction
What artery supplies the head of the femur?
The medial circumflex artery
