This engaging and fully-resourced lesson looks at the myogenic nature of cardiac muscle and explores the roles of the SAN, AVN and Purkyne tissue (bundle of His) in the initiation and control of heart action. The PowerPoint and accompanying resources have been designed to cover point 3.1.2 (g) of the OCR A-level Biology A specification. The lesson begins with the introduction of the SAN as the natural pacemaker and then time is given to study each step of the conduction of the impulse as it spreads away from the myogenic tissue in a wave of excitation. The lesson has been written to make clear links to the cardiac cycle and the structure of the heart and students are challenged on their knowledge of this system from topic 3.1.2. Moving forwards, students are encouraged to consider why a delay would occur at the AVN and then they will learn that the impulse is conducted along the Bundle of His to the apex so that the contraction of the ventricles can happen from the bottom upwards. The structure of the cardiac muscle cells is discussed and the final task of the lesson challenges the students to describe the conducting tissue, with an emphasis on the use of key terminology Due to the detailed nature of this lesson, it is estimated that it will take about 2 hours of A-level teaching time to cover the detail
