SA Practical 2 Flashcards
Gluteus Maximus Origin and Insertion
Org: Coccyx, edge of sacrum &posterior iliac crest
Ins: Illotibial tract and gluteal tuberosity
gluteus maximus action
Hip: extension, abduction and lateral rotation
Hip: adduction lower fibers
Gluteus Medius Origin and Insertion and it’s relationship to the gluteus minimus
Org: Surface of illium
Ins: greater trochanter
More posterior than minimus
Gluteus medius action
Hip: abduction, medial rotation
Hip: posterior fibers extend and laterally rotate
Gluteus Minimus Origin and Insertion and it’s relationship to the gluteus medius
Org: surface of ilium
Ins: greater trochanter
More anterior than medius
Gluteus Minimus action
Hip: abduction, medial rotation, flexion
minimus does all of the same things as medius except does not extend and or externally rotate hip because it’s fibers are more anterior
Rectus Femoris Origin and Insertion
Org: Anterior iliac spine
Ins: Tibial tuberosity
Rectus Femoris action
Hip: flexion
Knee: extension
Vastus Medialis origin and insertion
Org: linea aspera
Ins: Tibial tuberosity
Vastus Medialis action
Hip: flexion
Knee: extension
Vastus lateralis Origin and Insertion
Org: linea aspera, glut tuberosity, greater trochanter
Ins: Tibial tuberosity
Vastus lateralis action
Hip: flexion
Knee: extension
Vastus Intermedius Origin and Insertion
Org: ant/lat shaft of femur
Ins: tibial tuberosity
(says not on test because too deep to palpate but…)
Vastus Intermedius action
Hip: flexion
Knee: extension
Bicep Femoris Origin and Insertion
Org: long head (more superficial) = ischial tuberosity and short head (more deep) = linea aspera
Ins: head of fibula
Bicep Femoris action
Hip: extension and lateral rotation
Knee: flexion and lateral rotation
Semitendinosus origin and insertion
Org: Ischial tuberosity
Ins: medial shaft of tibia at pes anserinus
Semitendinosus and Semimembranosus action
Hip: extension and medial rotation
Knee: flexion and medial rotation
Semimembranosus origin and insertion
Org: Ischial tuberosity
Ins: medial condyle of tibia
Which is more medial, semimembranosus or semitendinosus?
the belly of semimembranosus is more medial but the semitendinosus crosses over the semimembranosus to insert more medially.
Psoas Major origin and insertion
Org: lumbar vertebrae
Ins: lesser trochanter of femur
Iliacus origin and insertion
Org: Illiac fossa
Ins: lesser trochanter
Iliopsoas action
Hip: flexion & lateral rotation
& Pelvis tilt (anterior for iliacus, post for psoas if asked)
Iliopsoas stands for
iliacus and psoas major
What is in the adductor group of thigh?
adductor magnus, longus, brevis, pectineus and gracilis
adductor group of thigh origin and insertion
Org: inferior ramus of pubis, ramus of ishium, ischial tuberosity
Ins: linea aspera and adductor tubercle
