fatigue fracture in the metatarsals
an alteration of the angle made by the axis of femoral neck to the axis so that the angle exceeds 135, making the femoral neck straighter
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

the hamstrings arise originate from?
painful condition of the anterior portion of the leg along the thin bone the tibia. Caused by swollen muscles in the anterior compartment

which artery supplies the most blood to the head and neck of the femur?
plantarflexors of the foot in which compartment?
roots of femoral nerve

saphenous nerve arises from which nerve?
reduced elasticity in veins that allow backflow of blood
what attaches to the adductor tubercle?
the ankle joint is what type of joint?
intermittent or continuous pain perceived as originating in an absent or amputated limb
the knee jerk reflex tests which nerve roots?
with the avulsion of the tendo calcaneus, which motion of the foot is compromised?
prevents overeversion of the foot

loss of plantar flexion suggests injury to which nerve?
innervates skin on the lateral leg and the skin on the dorsum of the foot

innervates skin in between 1st and 2nd toes
lateral sural cutaneous arises from which nerve?
ligament that prevents hyperextension of the knee

round ligament of the head of the femur
gluteal gait results in the paralysis of what muscle?
which nerve can be injured in intramuscular injection of medications?
provides sensation to the skin on the anterior and lateral aspects of the thigh
