Who Discovered Mitochondria

 Who Discovered Mitochondria
It is difficult to give one specific individual the credit for who discovered mitochondria. The entire course of development from the initial sighting to the eventual classification of the so-called power plant of the cell had a slow but steady progress, spanning over a century of research conducted by a succession of brilliant scientific minds. The history of mitochondria’s discovery began in 1857, when Swiss anatomist and physiologist Albert von Kolliker revealed the presence of granule-like structures in muscle cells. Kolliker’s claim was substantiated by other scientists at the time who had observed that the granules also appeared in other cell types. Then in 1886, a cytologist named Richard Altman employed a dye technique to identify the granules. Terming them “bioblasts,” Altman hypothesized that these organelles were the basic units of cell activity. It would be in 1898 that Carl Benda would rename the bioblast as “mitochondria,” taken from the Greek words “mitos”...

It was Richard Morton who first called the disease chickenpox. The work of William Heberden in 1767 showed how different chickenpox was from smallpox. The works of these people were crucial in bringing to light facts about chickenpox. Their studies allowed doctors to devise treatments for the disease. Signs and Symptoms The disease is caused by the varicella zoster virus (VZV). The most conspicuous symptom is a skin rash. These appear...

The Ebers Papyrus reflects a comprehensive Egyptian knowledge of the basics of heart failures and diseases and simple measure on how to treat them. With this fact, it would be safe to assume that the first heart doctor was an Egyptian.
