Deep Lateral Rotators of the Hip
| Iliacus is Palpable |
| Iliacus Origins - Iliac fossa of hip bone |
| Iliacus Insertions - Anterior side of the Lesser trochanter of femur |

Iliacus notes: Begins across the entire anterior edge of iliac crest. Goes in front the obturator foramen and femoral head. |
| Psoas Major is Palpable |
| Psoas Major origins - Anterior surface of L1-L5 transverse processes and vertebral bodies. (pictures show the origin near where transverse process meets vertebral body.) |

| Tensor Fascia Latae is Palpable |
| Tensor Fascia Latae origins - Anterior Iliac crest. Just behind where the ASIS meets the iliac crest. |
Tensor Fascia Latae insertions -Iliotibial band.
The iliotibial band is a thick band of tissue that begins at the iliac crest in the pelvis, runs down the outer part of the thigh, and crosses the knee to attach into the top part of the tibia or shinbone. The iliotibial (IT) band helps stabilize the knee through its range of motion. OnHealth.com Image |

| Biceps Femoris - GBS |
| Biceps Femoris - palpable |
Biceps Femoris - origins - Long Head: Ischial tuberosity and sacrotuberous ligament Short Head: Linea aspera of femur |
| Biceps Femoris - insertions -Head of fibula and posterior side of lateral condyle of tibia |
Biceps Femoris - actions -Flexion of the knee and Extension of the hip |
Biceps Femoris - Notes - Sacrotuberous ligament is a triangle the runs from the side of the sacrum and coccyx down to the ischial tuberosity. |
| Semimembranosis - GBS |
| Semimembranosis - palpable |
| Semimembranosis - origins - Ischial tuberosity |
| Semimembranosis - insertions -Posterior medial condyle of tibia |
Semimembranosis - actions -Flexion of the knee. Extension of the hip |
| Semimembranosis - notes - Most medial of the hamstrings. semimembranosis is medial to semitendonosis is medial to biceps femoris long head is medial t obiceps femoris short head Semimembranosis @ GetBodySmart |
| Semitendinosus - GBS |
| Semitendinosus - palpable |
| Semitendinosus - origins - Ischial tuberosity |
Semitendinosus - insertions - Pes Anserinus - just below the anterior medial side of the tibial condyle (also medial to the tibial tuberosity) (Pes Anserine muscle) |
Semitendinosus - actions -Flexion of the knee. Extension of the hip |
| Semitendinosus - notes - between semimembranosis and biceps femoris longhead Semitendinosus @ GetBodySmart |
| Sartorius - GBS |
| Sartorius - palpable |
| Sartorius - origins - ASIS (A.S.I.S.) |
Sartorius - insertions - Pes Anserinus - just below the anterior medial side of the tibial condyle (also medial to the tibial tuberosity) Sartorius - insertion anteromedial surface of the upper tibia in the pes anserinus |
Sartorius - actions -Flexion, abduction, and lateral rotation of hip. Flexion and medial rotation of knee |
Sartorius - Notes - Goes across the vastus medials. Inserts at same places as the semitendonosis. So maybe the Sartorius helps to flex the knee despite it's anterior position???? |
| Popliteus - GBS |
| Popliteus - unknown if palpable |
Popliteus - origin - lateral surface of lateral epicondyle on the femur. |
| Popliteus insertion -posterior surface of the body of tibia above the soleal line. |

| Pectineus - actions -Adduction of the hip |
| Pectineus - @ GetBodySmart |
| Gracilis - GBS |
| Gracilis - not palpable |
| Gracilis - origins - Pubis |
Gracilis - insertions - Pes Anserinus - just below the anterior medial side of the tibial condyle (also medial to the tibial tuberosity) |

| Adductor Magnus - GBS |
| Adductor Magnus - palpable |
| Adductor Magnus - origins Oblique head - inferior ramus of pubis & ischial ramus. Vertical head - ischial tuberosity. |
| Adductor Magnus - insertions oblique head inserts at Gluteal tuberosity, linea aspera, book does not mention gluteal tubersity. vertical head inserts at ischial tuberosity. |
| Adductor Magnus - actions -Adduction of the hip |
Adductor Magnus - Notes -The adductor magnus is really two different muscles that share a few fibers near the origin. There is the oblique head which is a large triangular band which is narrow near the pubis and ischium and fans out wide along the linea aspera. The vertical head is long and similar to the semimembranosis.
