Gluteal Thigh Flashcards
What bone of the pelvis do you sit on?
Ischium
What two bones articulate at the pubic symphysis?
The two ox coxae (pubis bones of ox coxae)
The […] attach to the ischial tuberosity.
Hamstring muscles
The linea aspera is on the […] surface of the femur and is an important site of muscle attachment.
Posterior
- What structures are shown?
- What are the areas in red?
Areas in red are weak spots that are more prone to injury.
What structure is shown?
Bursae, specfically the arrows are pointing to the trochanteric bursae. Of all the hip bursae, these are the most likely to become inflamed and are the most clinically significant.
- What muscles are shown?
- What are their actions?
- What are their innervations?
- Gluteus maximus; external rotation, extension, adduction and abduction of the thigh at the hip joint; inferior gluteal nerve
- Gluteus medius; abduction of thigh at hip and stabilization of hip; superior gluteal nerve
- Gluteus minimus; abduction of thigh at hip and stabilization of hip; superior gluteal nerve
- Tensor Fasica Lata; tenses the fascia lata (iliotibial tract or IT band); superior gluteal nerve
- IT band
MUSCLES 1 AND 2 ONLY

*
MUSCLES 3, 4, 5, and 6 ONLY
- What muscles are these?
- What are their actions?
- What are their innervations?
- Where do all of these muscles (including 1 and 2) attach?
All attach to greater trochanter
Where should intramuscular injections be given in the gluteal region and why?
- What muscles are shown?
- What are their actions?
- What are their innervations?
Describe the vascularization of the posterior leg.
Deep femoral artery (blue) provides blood supply to posterior (upper) leg. Via passage through the adductor hiatus it becomes the popliteal artery, which then divides into the anterior tibial, posterior tibial and fibular artery which supply blood to lower leg.
