In 1655 Hooke was employed by Robert Boyle to construct the Boylean air pump. Five years later, Hooke discovered his law of elasticity, which states that the stretching of a solid body is proportional to the force applied to it. -
Robert Hooke wrote about Micrographia and he used it to study all kinds of microscopic creatures. In 1665 he published his book Micrographia which detailed his observations and included drawings. In summary, Hooke is important to the study of cells because he greatly improved the microscope, microscopy, and coined the term "cell" as we use it today. -
The particles that he saw
under his microscope were motile and,
assuming that motility equates to life and in a letter October 9, 1676 he stated that they were living organisms. -
Scientist were able to see microscopic life particles and organism under the microscope. The invention of the microscope allowed scientists and students to study the microscopic creatures in the world we cannot see. When learning about the history of the microscope it is important to understand that until these microscopic creatures were discovered, the causes of illness and disease were theorized but still a mystery. -
living organisms are made up of cells, they are the basic structural/organizational unit of all organisms, and all cells come from pre-existing cells. -
He created the Black Reaction in 1873 and unlike the procedures that were available before its invention, the black reaction was able to reveal neurons in their entirety.
-
Santiago Ramón y Cajal became
the main supporter and indefatigable champion of the neuron theory. His neuroanatomical investigations contributed to the
foundations of the basic concepts of modern
neuroscience. -
Camillo Golgi created the black reaction technique, which enabled scientists to stain and view the structure of neurons, the specialized cells that compose the nervous system. -
1820-1896
A tissue that seemed to
belie cell theory nervous tissue. Because
of its softness and fragility, it was difficult to
handle and susceptible to deterioration. But
it was its structural complexity that prevented a simple reduction to models
derived from the cell theory -
1820-1896
Joseph von Gerlach was a German professor of anatomy at the University of Erlangen. He was a native of Mainz, Rhineland-Palatinate. Gerlach was a pioneer of histological staining and anatomical micrography.
In 1858, at the University of Erlangen in Erlangen, Germany, Gerlach created a staining technique that yielded evidence to support his reticular theory.
