Kinesiology Exam 3 Flashcards
4 bones of hip
ilium, ischium, pubis, femur
what are the 3 bones of pelvic girdle
ilium, ischium, pubis
ilium def
upper 2/5, most superior part of pelvic girdle
ischium def
most inferior, lower 2/5 of pelvic girdle
pubis def
most anterior part of pelvic girdle
what makes up the ball and socket joint of the hip
head of femur and acetabulum
what is illiac crest
top of pelvis @ beltline
ASIS def
part of the pelvic girdle, anterior PSIS
PSIS articulates with
sacrum and ishial tuberosity
what is obterator foramen
passage for hip rotators
what does hip move aka what do hip muscles all do
move femur
is greater trochanter of hip medial or lateral
lateral
is lesser trochanter medial or lateral
medial
what kind of joint is symphysis pubis
amphiarthrosis
what kind of joint is sacroiliac
not true gliding
what kind of joint is acetabular femoral joint
ball and socket
does it matter if the leg is flexed or extended for movements of hip
no, b/c the hip joint moves the femur. if lower parts of the lower extremities move it doesn’t entirely depend on the movement of the hip
what muscle originates at vertebral column
iliopsoas
why do we bend our knees to workout abs
so iliopsoas muscle isn’t being used
how many muscles make up iliopsoas
3 muscles, but can’t isolate them
what are the 3 prime movers for hip flexion
iliopsoas, rectus femoris, sartorius
what is the only anteriomedial muscle of the hip joint
pectineus
what does the pectinus do
adduction and flexion of hip
what muscle is usually injured for groin strain
pectineus
where does sartorius originate
ASIS
where does sartorius cross
at knee by the medial tibia
what movements do sartorius do
flexion hip, extension knee, external rotation thigh (grandpa sit)
what movements does rectus femoris do
extend knee and flex hip
what are 4 medial adductor muscles of hip
adductor brevis, adductor longus, adductor magnus, gracilis
what medial hip muscle does knee flexion
gracilis
where does gracilis cross
knee
when the leg is extended and adducting what medial hip muscles are working`
all adductors: adductor brevis, adductor longus, adductor magnus, gracilis
what is the largest medial hip muscle
adductor magnus
what is the smallest medial hip muscle
adductor brevis
when the leg is bent and adducting what muscle is being used
gracilis
4 posterior hip muscles
gluteus maximus, biceps femoris, semimembranosus, semitendinosus
3 lateral hip muscles
tensor fascia latae, gluteus medius, gluteus minimus
what is most superficial posterior hip muscle
gluteus maximus
what is considered the true hip extensor
gluteus maximus
what are lateral hip muscles that are prime movers in internal rotation
gluteus minimus, medius
what muscle inserts in IT band
tensor fascia latae
what lateral abductor also does flexion of hip
tensor fascia lata
compare gluteus medius and gluteus minimus
minimus is deeper and shorter
what are the 3 hamstring muscles
biceps femoris, semimembranosus, semiteninosus
where does biceps femoris insert
fibula
