Generation III reactor. Model of the Toshiba ABWR, which became the first operational Generation III reactor in 1996. A Generation III reactor is a development of Generation II nuclear reactor designs incorporating evolutionary improvements in design developed during the lifetime of the Generation II reactor designs.
The tibial nerve passes through the popliteal fossa to pass below the arch of soleus. In the popliteal fossa the nerve gives off branches to gastrocnemius, popliteus, soleus and plantaris muscles, an articular branch to the knee joint, and a cutaneous branch that will become the sural nerve.elow the soleus muscle the nerve lies close to the tibia and supplies the tibialis posterior, the flexor digitorum longus and the flexor hallucis longus. The nerve passes into the foot running posterior to the medial malleolus.
The main muscle in this area of the leg is the gastrocnemius, which gives the calf a bulging muscular appearance. Some nerves of the sacral plexus innervate this area, namely the superficial fibular nerve, the deep fibular nerve and the tibial nerve. The anterior tibial, posterior tibial, and the fibular arteries supply blood to the lower leg. These blood vessels supply oxygen and nutrients to the surrounding structuresâbones, muscles and nerves. The lower leg constitutes a major portion of a person's overall mass.
