Butts Butts Butts
This structure is found between the superior fibers of the gluteus maximum and the greater trochanter.
What is the trochanteric bursa?
This bone is triangular in shape, non-weight bearing, and contains 5-fused vertebrae.
What is the sacrum?
This hamstring muscle has an origin in the sacrotuberous ligament.
What is biceps femoris?
This rounded medial projection from the junction of the neck and body of the femur sits approximately 3 finger widths inferior and medial from the greater trochanter.
What is the lesser trochanter?
Innervation of:
Tensor fascia latae
Gluteus Medius
Gluteus Minimus
What is superior gluteal nerve (L4/L5/S1)?
These three muscles form the triceps coxae which occupies the gap between the piriformis and quadratus femoris.
What is:
Superior Gemelli
Inferior Gemilli
Obturator Internus
This landmark runs medial to lateral along the anterior surface of the pelvis dividing it into the true and false pelvis.
What is the arcuate line? (accept iliopectineal line or pectineal line)
Hip flexion
Abduction of the hip
Medial Rotation of the hip
Synergist to gluteus medius and iliopsoas
What is tensor fascia latea?
What is the trochanteric Fossa?
These are the two divisions of the sciatic nerve (L4-S3).
What is the tibial division and the common peroneal division?
This muscle divides he greater sciatic notch into two regions.
What is the piriformis?
The anterior border of the pubis bone is thickened to create the __________. This structure forms the anterior and superior border of the 2 pubic bones.
What is the pubic crest. (This pubic tubercle projects anteriorly on the superior ramus near the midline)
Knee flexion
Medial rotation of the knee
Hip extension
Medial Rotation of the hip
Posterior pelvic tilt
What is semitendinosus and semimembranosus?
This surface on the distal anterior femur extends higher on the lateral side than the medial side
What is the patellar surface?
What is gluteus maximus?
This landmark runs vertical from the iliac crest (just posterior to PSIS) to PIIS.
What is the posterior gluteal line?
Looking at the superior, anterior aspect of the sacrum you will find edge that as once the S1 vertebrae.
What is the sacral promontory?
What is the origin to vastus intermedius?
anterior and lateral surfaces of proximal 2/3 of femur shaft
lateral intermuscular septum
This bony landmark is one of the origins of vastus lateralis and vastus medialis which is continuous with the spiral line.
What is the Intertrochanteric line?
Obturator nerve (L2-L4)
Sciatic nerve (L4-S3)
What is adductor magnus
Adductor Part = obturator nerve
Hamstring Part = Sciatic nerve
These are the main actions of gluteus medius.
Hip abduction (all)
Anterior fibers - medial rotation of the hip
Posterior fibers - extension and lateral rotation of the hip
This structure is the origin of superior gemellus and the superior border of the lesser sciatic notch.
What is the ischial spine?
These are the main actions of Iliacus?
Hip flexion
Bilaterally - aids in trunk flexion when standing
Unilaterally - aids in trunk side flexion when standing
Stabilizes hip joint and lumbar spin
Anterior pelvic tilt
This small projection on the femur is found on the medial epicondyle and an insertion for adductor magnus.
What is the adductor tubercle?
This nerve is the largest branch of the lumbar plexus and enters the femoral triangle at the midpoint of the inguinal ligament.
What is the femoral nerve?
