The vertebral and basilar arteries supply blood to several structures in the brain including: the occipital cortex, the brainstem consisting of the midbrain, pons and medulla, the cerebellum and the thalamus. Atherosclerosis or hardening of the arteries is the primary cause of vertebrobasilar disease. The narrowing of the vertebral or basilar arteries caused by atherosclerosis creates vertebrobasilar insufficiency (VBI), or an insufficient delivery of blood flow to the posterior structures of the brain.
Pork loin is lean and high in protein. Pork is full of protein, but not all cuts of pork are lean and healthy. Protein is a major structural component of cells, tissues and organs. It also builds muscle mass and provides energy when carbohydrates and fat are not immediately available.
Pork isn't fundamentally much different than any other animal meat. Because pork meat doesn't tend to show the marbling common in beef -- this occurs when fat deposits form in the muscles themselves and makes the meat less lean -- it's easier to trim fat from pork than from beef.rotein Digestion. The first component of pork that your digestive tract starts breaking down is the protein. Assuming you eat a lean pork cut, the majority of the calories in the meat will come from protein, which is the molecule that makes up the muscle and large portions of nonmuscle cells.
