AH Biology 1.4d Part 1 - Nerve Impulse Transmission - Generation of a Nerve Impulse

Video tutorial of Advanced Higher Biology Unit 1 - Cells and Proteins, Key Area 4 Communication and Signalling. In this video I talk through the first part of nerve impulse transmission where nerve impulses are generated. We discuss action potentials, depolarisation, repolarisation and the importance of sodium and potassium ion channels.
