thigh, hip, groin, and pelvis Flashcards
adductor magnus
O: ramus of pubis
I: inferior on linea aspera of femur
A: adduction and external rotation, some hip flexion
N: obturator
gracilis
O: symphysis pubic and pubic arch
I: medial surface of tibia just below condyle
A: adduction and knee flexion
N: obturator
what supplies blood to the hip
medial circumflex femoral, deep femoral and femoral arteries
nerves: superficial great saphenous and femoral veins
pelvic bones
ilium, ischium, pubis, sacrum, coccyx
functions of the pelvis
weight bearing in sitting and standing
weight transference from axial to appendicular during movement
muscle attachment for those involved in support, posture and locomotion
contain and protect pelvic viscera
iliofemoral ligament
strong
prevents hypertextension, control external rotation and adduction of the hip and limits pelvis during any backward rolling of femoral head during weight bearing
it reinforces the anterior aspect of the capsule and is attached to the anterior iliac spine and intertrochanteric line of femur
pubofemoral ligament
prevents excessive abduction of the thigh and is positioned anterior and inferior to the pelvis and femur
ischiofemoral ligament
prevents excessive internal rotation and adduction of the hip and is located posterior and superior to the articular capsule
psoas major and minor
O: transverse processes and bodies of last and all lumbar vertebrae
I: lesser trochanter of femur
A: flexes hip and trunk of the femur
N: femoral and first lumbar
iliacus
O: iliac crest and fossa
I: lesser trochanter of femur
A: flexes hip and trunk
N: femoral and first lumbar
tensor fasciae latae
O: anterior portion of iliac crest and ASIS
I: ITB
A: tenses fasciae latae and helps flexion, abduction and internal rotation
N: superior gluteal
glute max
O: posterior gluteal line of ilium and posterior surface of sacrum and coccyx
I: gluteal tuberosity of the femur and ITB
A: extends and externally rotated the hip
N: inferior gluteal
glute med
O: outer surface of ilium between posterior and anterior gluteal lines
I: lateral surface of greater trochanter of femur
A: abducts and internally rotates the hip
N: superior gluteal
glute min
O: outer surface between anterior and inferior gluteal lines
I: anterior surface of greater trochanter of femur
A: abducts and internally rotates the hip
piriformis
O: anterior surface of sacrum
I: superior border of greater trochanter
A: external rotation, extension and abduction
N: second sacral
