ATTR 219Hip/Pelvis Study Guide1. Name the three parts of the pelvis:Sacrum, coccyx, innominates2. What is a primary function of the innominates?Protect reproductive organs3. Why do females have lighter/smoother innominates?Makes for easier/more effective child birth4. Identify three main parts of the innominates.Ilium, ischium, pubis5. Name the four spines of the iliumAnterior superior, anterior inferior, posterior superior, posterior inferior6. Between what two features is the ischial spine located?Greater/lesser sciatic notch7. What happens when the size/width of the pelvic outlet is too small on a pregnant woman?She must have a C-section8. The pubic arch is formed by what structure?Inferior pubic rami9. Where is the obturator foramen located?Opening between the pubis and ischium10. The acetabulum articulates with what other major bony feature?Head of the femur11. The anterior thigh muscles primary perform what action?Flex of hip and trunk12. Identify the 2 muscles that make up the iliopsoasIliacus and psoas major13. The iliacus is innervated by what nerve?Femoral14. True or false- All of the medial thigh muscles are innervated by the anterior branch of the obturator.False- Adductor magnus is innervated by posterior branch of obturator15. What is the purpose for the neck of the femur offsetting the thigh from the hip?Allows for a better/smoother movement and range of motion16. Describe the trochanteric fossa.It is a deep depression on the medial side of the greater trochanter17. The gluteal tuberosity continues distally as what?Linea aspera18. What is the purpose of the labium acetabulare?It helps to deepen the sock of the join, as it is a fibrocartilage rings that surrounds the acetabulum19. The femoral triangle base is formed by what ligament?Ingiunal ligament20. Scarpa’s Triangle is a junction between what two muscles?Adductor longus and Sartorius21. Identify the 3 ligaments that reinforce the hip joint and joint capsule.Iliofemoral, pubefemoral, and ischiofemoral22. To how many degrees can the hip flex? Extend?Flex- 135 Extend- 3023. True or False- The obturator is the largest nerve in the body.False- the sciatic is the largest nerve in the body24. True or false- The femoral nerve innervates the Sartorius and quadricepsTrue25. All of the gluteal muscles get some blood supply from what artery?Superior gluteal26. The femoral artery is a continuation of what other artery?External iliac artery27. The obturator artery gives blood supply to what?Bladder, ilium and adductor muscles, and hip joint28. Where is the trochanteric bursa?Behind greater trochanter and deep to gluteus maximus and tensor fascia latae29. Name the 6 external rotator muscles from top to bottomPiriformis, gemellus superior, obturator internus, gemellus inferior, obturator externus, quadricep
