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.
They join the posterior tibial veins in the upper calf. TIBIAL/PERONEAL TRUNK This short vein segment is located in the upper calf, where the posterior tibial and peroneal veins join. POPLITEAL (POP) The popliteal vein begins as the anterior tibial vein joins the tibial/peroneal trunk in the upper calf.
