Introduction | History of Empiricism. Empiricism is the theory that the origin of all knowledge is sense experience. It emphasizes the role of experience and evidence, especially sensory perception, in the formation of ideas, and argues that the only knowledge humans can have is a posteriori (i.e. based on experience).
The main anatomic structures of the posterolateral aspect of the knee are the lateral (fibular) collateral ligament (LCL) , the popliteus tendon and the popliteofibular ligament.
1 Popliteal artery: A branch of the femoral artery, the popliteal artery branches further to supply blood to the knee, thigh, and calf. 2  It ends at the anterior and posterior tibial arteries. 3  Posterior tibial artery: This branch of the popliteal artery supplies oxygenated blood to the leg and sole of the foot.n Depth: Vessels. Once blood is oxygenated in the lungs, it returns to the heart and is then pumped throughout the body. A web of blood vesselsâarteries, veins, and capillariesâcirculate blood to organs, muscles, bones, and other tissues.
