fatigue fracture in the metatarsals
fracture of the neck of the femur would most likely result in the injury of which artery?
roots of superior gluteal nerve
occurs when the contents of the abdomen (usually part of the small intestine) push through a weak point or tear the thin muscular wall of the abdomen, which holds the abdominal or
LE Unit 1
test for the integrity of the cruciate ligaments
what attaches to the adductor tubercle?
a deformity in which the tibia is bent or twisted laterally.
this meniscus is hurt more due to its association with the tibial collateral ligament
femoral artery arises from

the hip joint is deepened by the?
an alteration of the angle made by the axis of femoral neck to the axis so that the angle less 135. making the femoral neck more horizontal

oburator nerve arises from?
with the avulsion of the tendo calcaneus, which motion of the foot is compromised?
pathway for the piriformis muscle
loss of plantar flexion suggests injury to which nerve?
arises from the intercondylar area of tibia and inserts into medial lateral condyle of the femur

lateral sural cutaneous arises from which nerve?
sudden involuntary painful contraction of muscles of the lower limb. Caused by muscle fatigue, overexertion, dehydration, and depletion or imbalance of salts and minerals.
lesser saphenous vein drains into
weakened abduction of the thigh and a gluteal gait suggest damage to which nerve?
innervates skin in between 1st and 2nd toes
roots of femoral nerve
fracture to the shaft of the fibular neck would most likely injure what structure and cause foot drop?
provides insertion for tensor fascia lata and gluteus maximus
