Frog Heart Preparation

Overview

This laboratory procedure module explains the process of isolating and mounting a frog heart for the study of cardiac cell excitation. It includes a video demonstration of the procedure to guide student to be able to understand, and on his own, isolate and mount a tissue without supervision at the laboratory.

Introduction

 

An isolated frog heart preparation is useful in the study of cardiac cell excitation. The small size of the frog's heart means that drugs applied to the outside of the heart will peneterate the myocardium and modify the functions of the heart's cardiac chambers. Thus, the effect of the autonomic neurotransmitter substance together with their modification by other drugs can be studied by addition of these agents to the heart.

 

Objectives

 

Student should be to able to isolate and mount the tissue.
