studying the anatomy of frogs and electrophysiology. In the 1780’s‚ he began to experiment with animal electricity. One day‚ Galvani was experimenting at the University of Bologna with frogs and test charges. It was known that if you applied a charge to the spinal cord of a frog‚ that it would cause the frog to have muscular spasms throughout it’s body. He found that the electric current supplied by a Leyden jar‚ would be powerful enough to causes the leg muscles of a frog to twitch or contract

creature is noted in the lines‚ “She had no quarrel with the snakes. They kept down the rats and the frogs.” The narrator’s hint at the importance of the ecological food chain in the lines cannot be overlooked.

First of all we have to defreniate between the musle stenght and muscles power. Musle stenght: Muscular strength defined as the ability of a muscle /group of muscles to contract with maximal force. Muscular strength describes how strong a muscle is or how much force it can exert. Exercise professionals often measure muscular strength by determining the maximum weight a person can lift at one time. There are 2 components to gain muscles strength; 1) The neural component (short-term). 2) The hypertrophic

In fairy tales we see this in every story that happens. There are clear cut morals that resound from the pages of these tales‚ one of which being ‘The Frog King‚ Or Iron Heinrich’ we see how a girl tries to sway a from out of a deal‚ “The princess thought‚ ‘What is this stupid frog saying?

The muscle physiology of skeletal muscle was observed by using electrical‚ physical‚ and neural stimulations of an isolated gastrocnemius muscle from Rana pipiens. The gastrocnemius receives signals from the action potentials of the sciatic nerve. The muscle contraction is caused by the binding of a neurotransmitter once the action potential reaches the neuromuscular junction. Stimulation of the muscle and the sciatic nerve allows for recording and measuring of these properties. We observed twitch

The Anatomical and Physical Features of Frogs Abstract: People have always wondered how frogs have the capability to live in both wet and dry environments. So why not dissect a frog to find out how. Frogs have both physical features like their skin that allows them to breath in water. They also have anatomical features like humans that allow them breath air just like us. Introduction As many people have learned throughout elementary and middle school amphibians are animals that have the

Discovery of New Poison Dart Frog Biologists have discovered a new species of dart frog in the headwaters of the Rio Cano in Panama. This newly found frog has been named Andinobates geminisae after Geminis Vargas. Geminis Vargas is the wife of Marco Ponce who supported him toward the discovery of the new dart frog species. The new dart frog is very small about 12.7 millimeters in length and it is about the same size of a fingernail. Although the new dart frog is very small in size; it contains
