Question

leonardo davinci conducted experiments on fog to find the importance of spinal cord. give another example??

Answer 1

Answer:

The earliest surviving anatomical drawings by Leonardo relate to this debate. Dating from circa 1487, they show what is thought to be his only experiment on living animals, in which he pierced the spinal column of a frog. On one sheet, next to a drawing of the base of the skull, Leonardo describes what he did,

… the frog retains life for some hours when deprived of its head and heart and all its bowels. And if you puncture the said nerve [spinal medulla] it immediately twitches and dies. All nerves of animals derive from here [spinal cord]. When this is pricked, the animal dies at once.
