Muscles of the Hip and Thigh - Origins & Insertions Flashcards
Iliacus
- O: iliac crest and iliac fossa; sacrum
* I: lesser trochanter (femur)
Psoas major
- O: vertebrae
- I: lesser trochanter
- A: flexes thigh
Rectus femoris
- O: Ilium
- I: tibial tuberosity (through patellar tendon and ligament)
- A: flexes thigh; extends leg
Vastus lateralis`
- O: greater trochanter and linea aspera (femur)
- I: tibial tuberosity (through patellar tendon and ligament)
- A: extends leg
Vastus intermedius
- O: femur
- I: tibial tuberosity (through patellar tendon and ligament)

Vastus medialis
- O: linea aspera
- I: tibial tuberosity (through patellar tendon and ligament)
- A: extends leg
Sartorius
o O: ilium
o I: tibia
o A: flexes thigh and leg; rotates thigh
tensor fasciae latae
o O: iliac crest
o I: Iliotibial band
o A: flexes, abducts, and rotates thigh
Gluteus maximus
o O: ilium; sacrum; coccyx

What is the iliopsoas complex and what muscles are included?
Made of two muscles that share the same tendon for insertion. Muscles include:iliacus musclepsoas major
What is the quadriceps femoris group and what muscles are included in it?
Group of four muscles that share the same tendon for insertion. Muscles include: Rectus femorisVastus lateralisVastus intermediusVastus medialis
What muscles are included in the hamstring?
Biceps femorisSemitendinosusSemimembranosu
What is the patellar tendon/ligament?
They are technically the same structure; specifically, the patellar tendon extends from the quadriceps femoris group to the patella while the patellar ligament extends from the patella to the tibial tuberosity.
What does the patellar tendon extend from and to?
Extends from the quadriceps femoris group to the patella
What does the patellar ligament extend from and to?
Extends from the patella to the tibial tuberosity
