Question | Answer |
---|---|
Rectus Femoris | o: anterior inferior iliac spine of the coxal bone (AIIS) i: base of patella - tibial tuberosity (via infrapatellar tendon) |
Rectus Femoris main actions (2) | - hip flexion (thigh) - pelvic anteversion |
Sartorius | o: anterior superior iliac spine of the coxal bone (ASIS) i: medial epicondyle of the tibia |
Sartorius main actions (3) | - hip flexion (thigh) - external hip rotation - pelvic anteversion |
Gluteus Maximus | o: posterior gluteal line of the gluteal fossa of the coxal bone - sacrum i: superior portion of the linea aspera of the femur - superior 1/3 of the iliotibial tract |
Gluteus Maximus main actions (4) | - hip extension - external hip rotation - pelvic retroversion - hip abduction |
Gluteus Medius | o: gluteal fossa between anterior and posterior gluteal line of coxal bone i: greater trochanter of femur |
Gluteus Medius main action | hip abduction |
Biceps Femoris | o: long head- ishial tuberosity of coxal bone, short head- inferior portion of linea aspera of femur i: head of the fibula, lateral epicondyle of tibia |
Biceps Femoris main actions (2) | hip extension, pelvic retroversion |
Semitendinosus | o: ishial tuberosity of coxal bone i: proximal segment of antero-medial aspect (medial condyle) |
Semitendinosus main actions (2) | hip extension, pelvic retroversion |
Semimembranosus | o: ishial tuberosity of coxal bone i: proximal segment of postero-medial groove |
Semimembranosus main actions (2) | hip extension, pelvic retroversion |
Iliotibial Tract | o: medial portion of iliac crest of coxal bone i: head of fibula, lateral epicondyle of tibia |
what is the iliotibial tract | a tight string of connective tissue that runs the length of the lateral segment of the thigh |
Tensor Faciae Latae | o: anterior portion of iliac crest of coxal bone i: superior 1/3 of the iliotibial tract |
Tensor Faciae Latae main actions (4) | hip flexion, hip abduction, internal hip rotation, pelvic anteversion |
Adductor Gracilis | o: ishio-pubic segment of coxal bone i: linea aspera of femur, medial epicondyle of tibia |
name the 3 hamstrings | biceps femoris, semitendinosus, semimembranosus |
what origin do the 3 hamstrings share | ishial tuberosity of the coxal bone |
what two bones make up the functional group of the hip | the femoral head and the coxal bone |
what bones make up the pelvis | 2 coxal bones and the sacrum |
what bones make up the coxal | ilium, ishium, pubis |
what are the possible actions at the coxofemoral joint | flexion and extension, abduction and adduction, internal and external rotation |
what are the possible actions at the pelvis | elevation and depression, anteversion and retroversion |
which 3 muscles share the linea aspera | short head of the biceps femoris (inferior portion,as origin), adductor gracilis (insertion), gluteus maximus (superior portion, as insertion) |
which 2 muscles share the insertion of superior 1/3 of the iliotibial tract | tensor fasciae latae, gluteus maximus |
how many muscles make up the hip adductors | five |
