Question

Silver nitrate solution was used to study nervous tissue by
A. Camilio Gorgi
B. Robert Hooke
C. Antonie Van Leeuwenhoek
D. None of the above

Answer 1

It was called the black reaction. The method was discovered in 1873. This was the study on the organization of the nervous system. Using this technique, we could come to know about the double impregnation term.

Complete answer:
Nervous tissue the network formed by our brain cells. There was an experiment conducted to visualize the nervous tissue under the light microscopy.

Let us learn the inventions by the scientists in the options.

Option A- Camilio Gorgi: Gorgi method/stain was named after Camilio Gorgi. He discovered the silver staining technique to visualize nervous tissue under the light. According to him-immersing, the formaldehyde-fixed brain tissue into an aqueous solution of potassium dichromate for 2 days. Then drying the block with filter paper. Followed by the immersion of block in the 2% aqueous solution of silver nitrate for 2 days and dehydrating it immediately with ethanol will give the detailed ultrastructure of the brain cells.

Option B -Robert Hooke: He was the one who discovered the Law of Elasticity and the cell. He named the cells so.

Option C -Antonie Van Leeuwenhoek: He is the father of microbiology. He is known for his work in microscopy. He started the era of microbiology. He was the one to know about the unicellular organisms first.

So the answer is option A: Camilio Golgi

Note: Nervous tissue is found in the brain, spinal cord and the nerves. They control the coordination in our body. It stimulates muscle relaxation and contraction. It plays a major role in controlling our emotions, reasoning and memory. It makes up the CNS and PNS of the nervous system.
