Two major theories were proposed regarding the nervous system: the reticular theory by Josef van Gerlach‚ and the neuron doctrine theory.1 Eventually‚ in 1873‚ an Italian scientist named Camillo Golgi discovered a staining technique that allowed the neurons and the fibers

information presented in this module along with additional outside research to answer the questions: 1. Describe how applied microbiology is used to improve aspects of life and the environment. Microbiology is the study of microorganisms (VanMeter‚ VanMeter‚ & Hubert‚ n.d.‚ p.3). These are all of the things not visible to the human eye. With the study of microbiology‚ it enables us to find things such as viruses and bacteria. This is helpful because sickness and certain outbreaks can be prevented
