Presentation on theme: "Ms. Bowman.  Pelvis Two innominates articulate with the sacrum to form the sacroiliac joint  Innominates formed by the fusion of the ilium, ischium,"— Presentation transcript:

1 Ms. Bowman

2  Pelvis Two innominates articulate with the sacrum to form the sacroiliac joint  Innominates formed by the fusion of the ilium, ischium, and pubis  8 bones in pelvis  Sacrum  Coccyx  Ilium-2  Ischium-2  Pubic-2

5  Support the spine and trunk  Transfer weight from trunk to lower limbs  Attachment site for muscles of the trunk and thigh  Protection of the pelvic organs

6  Hip Formed by the articulation of the femur and the acetabulum of the pelvis  Forms ball and socket joint

7  Longest and strongest bone in the body  Articulates with the tibia to form the knee and the pelvis to form the hip

8  Significantly less moveable than shoulder, but much more stable  Neck of the femur has little blood supply

9

10  Origin- outer surface of ilium and posterior surface of sacrum and coccyx  Insertion- proximal posterior femur, iliotibial band  Action- extends and externally rotates the hip

11  Origin- outer edge of iliac crest  Insertion- iliotibial tract  Action- flexes, abducts, and internally rotates hip

12  Origin- proximal outer surface of ilium  Insertion- lateral surface of greater trochanter of femur  Action- abducts hip, internal and external rotation of the hip

13  Origin- middle outer surface of ilium, below gluteus medius  Insertion- anterior border of greater trochanter of femur  Action- abducts and laterally rotates hip

14  Origin- internal surface of sacrum  Insertion- greater trochanter of femur  Action- externally rotates hip, abducts thigh

15  Origin- ischial tuberosity, proximal posterior femur  Insertion- semimembranosis:posterior medial condyle of femur; semitendinosus: proximal medial surface of shaft of tibia; biceps femoris: head of fibula, lateral condyle of tiboa  Action- knee flexion, hip extension

16  Origin- anterior part of pubic bone, ischial tuberosity  Insertion- medial side of femur  Action- adduct and laterally rotate hip

17  Origin- distal margin of pubic bone  Insertion- proximal medial surface of shaft of tibia  Action- adducts hip, flexes knee

18  Origin- anterior superior iliac spine  Insertion- proximal medial tibia  Action- flexes hip, externally rotates hip, abducts hip, flexes knee,

19  Origin-rectus femoris: front part of ilium vastus group: proximal shaft of femur  Insertion- patella via patellar tendon  Action- extends knee, flexes hip
