Appendicular Lower Extremities Flashcards
muscles that produce ___, ____, and ____ originate on superior pelvic girdle
flexion, extension, abduction
those that do ___ are anterior while ____ are posteriopr
flexion, extension
muscles producing _____ originate inferior/posterior
lateral rotation
muscles producing ____ originate inferior/anterior
adduction
muscles that make up the hamstrings are?
biceps femoris, semitendinosus, and semimembranosus
muscles in posterior compartment of thigh?
biceps femoris, semitendinosus, and semimembranosus
muscles in medial compartment of thigh?
adductor magnus, adductor longus, and gracilis
4 muscles that make up quadriceps
vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris
muscles in anterior compartment of thigh
vastus lateralis, vastus medialis, vastus intermedius, rectus femoris, and sartorius
___ and ____ are important in stabilizing pelvis when opposite lower limb is lifted off the ground
gluteus medius and minimus
actually two nerves (tibial and common fibular) and splits around knee; as descends through thigh it sends branches to ___ and ____; what nerve and what are blanks?
sciatic, hamstring muscles/adductor magnus
what muscle is the only knee flexor that originates superior to the acetabulum?
sartorius
what are the actions of the sartorius used for?
sitting on the floor with legs crossed
where does the magnus insert other than the pubis?
ischium
Strong band of CT that spans the lateral aspect of thigh from ilium to the tibia
iliotibial tract (IT band)
band of dense connective tissue deep fascia that encircles the entire thigh, under which the tensor fascia latae lies
fascia lata
flattens lateral side of thigh and strengthens extended knee when gluteus maximus and tensor fasciae latae are contracted?
IT band (Dense Irregular CT), stabilizes knee joint
where else does the gluteus maximus insert other than the gluteal tuberosity?
IT band
formed by the inguinal ligament, lateral border of adductor longus muscle (medial), and border of sartorius (lateral)
femoral triangle
what does the femoral triangle contain?
femoral nerve, femoral artery, femoral vein, and deep inguinal lymph nodes
insertion of catheters in ___ for cardiac catheterization, coronary angiography; inguinal hernias appear in this area
femoral artery
hamstring muscles are as effective at flexing knee as they are at extending thigh: T or F?
T
Like gluteus maximus, hamstrings are active during normal walking. T or F?
F
Tight hamstrings limit…
hip flexion
extend toes 2-4 at interphalangeal joints and flex toes 2-4 at metatarsophalangeal joints
lumbricals
adduct and flex proximal metatarsophalangeal joints and extend toes at interphalangeal joints
palmar interossei
abduct and flex toes 2-4 at metatarsophalangeal joints and extend toes at interphalangeal joints
dorsal interossei
