Who experimented with the dissected leg of a frog?
Correct answer: D. Galvani
- A. Volta
- B. Jenner
- C. Salk
- D. Galvani
Explanation

About Neurons and Nerve Impulse
Neurons receive and transmit information through dendrites, the cell body and axons. The topic explains resting potential, depolarization, repolarization, refractory periods and saltatory conduction, followed by synaptic transmission through neurotransmitters. An action potential is distinct from the graded potential produced at a receptor.
