man to witness a live cell under a microscope was Antonie Phillips van Leeuwenhoek‚ who in 1674 described the algae Spirogyra and named the moving organisms animalcules‚ meaning "little animals". Leeuwenhoek probably also saw bacteria. In 1839‚ Theodor Schwann and Matthias Jakob Schleiden suggested that cells were the basic unit of life. In 1858‚ Rudolf Ludwig Virchow concluded that all cells come from pre-existing cells‚ thus completing the classical cell theory. Classical Interpretation of the Cell

disorder research paper is about neurofibromatosis‚ which is a genetically-inherited disorder in which the nerve tissue grows tumors that may cause serious damage by compressing nerves and other tissues. The disorder affects all neural cells such as the Schwann cells and melanocytes. The melanocytes function abnormally in this disease‚ resulting to disordered skin pigmentation. The tumors would be able to cause bumps under the skin‚ colored spots‚ skeletal problems‚ and other neurological problems. Neurofibromatosis
