Exam 2

Gluteus Maximus

o: Posterior Illiac crest, Scarum, and sacrotuberous ligament

I: Grater trocanter of femur, gluteal tiberosity, and leteral tibial condyle

Innervation: Inferior Gluteal Nerve, L5-S2

Function: extends hip, externally rotates hip, abducts and adducts hip

Gluteus Medius

O: External surface of the illium between anterior and postior gluteal lines

I: Lateral surface of grater trocanter of the femur

Innervation: superior gluteal nerve, L4-S1

Function: abdcuts the hips, flexs hip, interally rotates hip, extends the hip, externaly rotates hips

Gluteus Minimus

O: external surface of the illium between the anterior & inferior gluteal lines

I: Anterior border of the grater torcanter of the femur

Innervation: superior gluteal nerve, L4-S1

Function: Abducts the hips, internally rotates the hip, slightly flexes the hip

Gluteal muscles

Gluteus Minimus, Gluteus Medius, Gluteus Maximus

Lateral rotators of the hip

Piriformis, Quadratus femoris,

Quadriceps

Rectus femoris, vastus lateralis, vastus intermedius, vastus medialis

Rectus femoris

o: Anterior illiac spine (AIIS)

I: Tibial tubersosity via the patellar tendon

Innervation: Femoral nerve, L2-L4

Function: flexes the hip, extends the knee

vastus lateralis

O: Grater trocanter of the femur, gluteal tiberosity, and poroximal lateral hip of the linea aspera

I: tibial tuberosity via the patellar tendon

Innervation: femoral nerve, L3-L4

Function: extends the knee

vastus intermedius

O: Proximal two/thirds of anterior shaft of the femur

I: tibial tuberosity via the patellar tendon

Innervation: femoral nerve, L2-L4

Function: Extends the knee

vastus medialis

O: Interochanteric line and medial lip of linea aspera of the femur

I: tibial tuberosity via the patellar tendon

Innervation: femoral nerve, L2-L4

Function: extends the knee

Iliac crest

the top border of the ilium, which is the largest bone in the pelvis. It runs from the anterior superior iliac spine (ASIS) to the posterior superior iliac spine (PSIS).
