Document Summary
Compound action potential in the frog sciatic nerve. Purpose: this exercise is designed to familiarize the student with the basic principles of nerve conduction. Performance objectives: at the end of the exercise the student should be able to: Measure the conduction velocity of the frog sciatic nerve. Determine if a nerve is able to conduct electrical signals in two directions. Define resting potential, action potential, compound action potential. Explain what is meant by compound action potential. Draw a picture of the laboratory setup used for this exercise. Find and dissect the frog sciatic nerve for placement in a nerve chamber. Describe the dissection of the frog sciatic nerve. Explain the procedure and significance of a single and double pith of the frog. The interior of a neuron at rest is negatively charged with respect to its exterior. Membrane potential (rmp) is a measure of this difference in charge across a cell"s membrane.
