The serous pericardium, in turn, is divided into two layers, the parietal pericardium, which is fused to and inseparable from the fibrous pericardium, and the visceral pericardium, which is part of the epicardium. Both of these layers function in lubricating the heart to prevent friction during heart activity.The visceral layer extends to the beginning of the great vessels (the large blood vessels serving the heart) becoming one with the parietal layer of the serous pericardium.oth of these layers function in lubricating the heart to prevent friction during heart activity.

They are designed for health professionals to use, so you may find the language more technical than the condition leaflets. Wernicke-Korsakoff syndrome (WKS) is a spectrum of disease resulting from thiamine deficiency, usually related to alcohol abuse. Wernicke's encephalopathy was originally described by German neurologist Karl Wernicke in 1881 as a classic triad of symptoms (mental confusion, ataxia and ophthalmoplegia).
Wernicke's encephalopathy is a degenerative brain disorder caused by the lack of thiamine (vitamin B1). It may result from alcohol abuse, dietary deficiencies, prolonged vomiting, eating disorders, or the effects of chemotherapy.ymptoms include mental confusion, vision impairment, stupor, coma, hypothermia, hypotension, and ataxia. Korsakoff's amnesic syndrome-a memory disorder-also results from a deficiency of thiamine, and is associated with alcoholism. The heart, vascular, and nervous system are involved.
