He performed experiments at the University of Bologna involving electric charges on frogs. A charge was applied to the spinal cord to a frog‚ and caused the frog to produce muscular spasms. The charges could make frogs jump even if the legs were no longer attached to the frog. Galvani believed that he was seeing animal electricity‚ the life force within the muscle of a frog (Corrosion Doctors).

isolated frog muscle could be made to contract when the sciatic nerve was irritated with a metal object‚ conducted the first muscle experiments between 1661 and 1665.

The kymograph‚ which was invented in the late 1840’s lead to the revolution of experimental physiology because it enabled muscle contractions to be analyzed and recorded. The muscle cell or fiber is the basic unit of a muscle. The frog gastrocnemius

Deforestation‚ overpopulation‚ science and ethics‚ urban expansion and global warming are just five of the main reasons humans can be to blame for the extinction and endangerment of animals.

so it doesn’t have to worry much about competition from other animals. As I learned from Jurassic Park‚ frogs can change its sex if there are many other frogs of the same sex in the same area.

The Northern Leopard Frogs live up to 12 years. I’d say in "frog years" one year would be thirty frog years‚ and 7 dog years. That’s crazy.
