A17 Frog Heart Intracellular Action Potentials


This BSL PRO lesson examines and records action potential from cardiac tissue in an amphibian. The lesson procedure and template were developed for BSL 4.0.1 or above.

Experimental Objectives

  1. To make an intracellular electrical recording in cardiac tissue.
  2. To observe and understand the electrical properties of myocardial cells in the vertebrate heart.
  3. To develop an understanding of the ionic basis of the electrical signals in cardiac tissue.
  4. To study the effects of pharmacological probes on the cardiac action potential.
